1.Why can electric bending machines achieve such high precision? This is inseparable from its driving principle: Direct drive, no intermediate variables: The all-electric bending machine uses a servo motor and a ball screw to directly drive the slider to move. This structure does not have the problems such as oil temperature changes, oil viscosity and leakage that exist in hydraulic systems, and these are precisely the main reasons for the precision drift of hydraulic presses. Closed-loop control: The system monitors the positions of the servo motor and the slider in real time through a high-resolution encoder and feeds the data back to the controller. Once a minor deviation is detected, the controller will immediately issue an instruction for correction, forming an accurate closed-loop control. No mechanical clearance: The precise ball screw and rigid structure design ensure an extremely small backlash, further guaranteeing positional stability.   2. Understand the accuracy indicators: positioning accuracy vs. repeat positioning accuracy When evaluating a bending machine, there are two related but distinct concepts: Positioning accuracy: It refers to the overall error between the actual position reached by the slider and the target position required by the instruction. It is more like an "absolute" precision. Repeat positioning accuracy: It refers to the consistency of the slider when it returns to the same target position in multiple attempts. This is a more important "relative" accuracy indicator. A vivid metaphor: Imagine shooting at a target. High positioning accuracy means that all bullet holes are concentrated near the aiming point (bullseye). High repeat positioning accuracy means that all bullet holes are closely clustered together, even if they may not be on the bullseye. For bending processing, the repeat positioning accuracy is often more important than the absolute positioning accuracy. Once the perfect bending position is found through the first piece's debugging, the machine must be able to precisely return to that position tens of thousands of times to ensure that the angles of all workpieces in mass production are consistent.   3. Factors affecting actual accuracy Even if the repeat positioning accuracy of the machine itself is very high, the following factors still need to be considered in actual production Eccentric loading processing: When the bending force is unevenly distributed at both ends of the worktable, it may cause slight torsional deformation. High-end electric bending machines will adjust the positions at both ends in real time through an automatic Y-axis compensation function to counteract this effect. Mold and machine tool rigidity: Any minor elastic deformation will affect the final outcome. Both the machine tool itself and the upper and lower dies used must have sufficient rigidity. Ambient temperature: Although the electric bending machine is not sensitive to temperature, extreme temperature changes in the workshop may still have a minor impact on the mechanical structure.   4. How to verify this indicator? When communicating with suppliers, you can ask questions like this to get reliable answers: May I ask what the exact repeat positioning accuracy listed in your official technical specification is? On what standards (such as ISO, JIS) is the test based?" Was this precision data measured in a cold or hot machine state? High-performance machines should maintain accuracy throughout the entire operating temperature range. Could you provide a third-party test report or demonstrate it on the spot during the test run? Summary ±0.0004 inches (±0.01 millimeters) can be regarded as the reference line for high-performance all-electric bending machines. Many top manufacturers can even offer an accuracy of ±0.0002 inches (±0.005 millimeters) or higher.   if you have more ideas, please contact us!

1. Accurately convey core values and address the "pain points" of factories When promoting, it is necessary to explain the direct economic benefits it can bring in a language that factory owners and production managers can understand. "One machine replaces multiple lines", saving space and initial investment Promotional point: There is no need to purchase separate punch presses and laser machines, reducing the floor space occupied by the equipment, power configuration and basic investment. Tell the factory owner: "You only need one investment to establish a complete sheet metal processing unit, which is particularly suitable for new factories with limited factory space or those planning new production lines." Minimize processes to the extreme to enhance efficiency and delivery time The promotional point: It eliminates the process of transferring, re-clamping and secondary positioning between the punch press and the laser machine. The sheet is clamped once to complete all processing. Tell the production manager: "The delivery time of your products can be shortened by 30% to 50%." Because there is no intermediate flow or waiting time, it is particularly suitable for small-batch and multi-variety urgent orders. Break through design limitations and empower high value-added products Promotional points: The mold-free nature of lasers enables them to easily cut any complex shapes and inner cavities. The high efficiency of stamping allows for rapid processing of louvers, bumps, threaded holes, etc. Tell R&D/designers: "You can freely design complex products without being restricted by molds." Laser cutting creates elegant curves, and stamping instantly forms functional structures, making your products more unique and competitive in the market. Reduce reliance on highly skilled operators Promotional point: One device, one set of programming software (usually integrating stamping and laser functions), and one operator can complete the entire process from programming to production, reducing management and labor costs.   Second, innovate business models and lower application thresholds The high initial investment is the main reason why many small and medium-sized factories are deterred. It needs to be resolved through a flexible business model. Financial leasing and installment payments Cooperate with financial institutions to offer flexible installment or lease plans for factories, converting huge capital expenditures into manageable monthly operating costs. "Trade-in" program Encourage factories with old single-function punch presses or laser machines to upgrade their equipment, use the old equipment to offset part of the purchase price, and accelerate equipment iteration. Establish demonstration factories and experience centers Establish demonstration sites in industrial zones to allow potential customers to witness the efficient operation of the equipment with their own eyes. They can also bring their own samples for on-site sampling and convince them with actual results. Cooperate with the sheet metal industry chain Cooperate with sheet material suppliers, spray painting factories, etc. to provide their customers with packaged solutions of "equipment + materials + post-treatment", increasing their appeal.   Third, promote technological popularization and enhance usability to remove usage obstacles Make the factory feel that it is "user-friendly, daring to use and easy to use". Develop more intelligent and integrated software The software should be capable of automatically identifying the features of the drawings, intelligently recommending whether to use stamping or laser processing (for example, small round holes and holes of the same batch should be stamped, and complex contours should be processed with laser), and automatically generating the optimal processing path to reduce programming difficulty. Provide strong technical training and support We offer a full range of training from programming, operation to maintenance. Establish a rapid response local service team to provide 7x24-hour technical support and solve the factory's worries. Modular and upgradable design Provide the basic model and reserve the upgrade interface. Factories can first purchase configurations that meet current needs. In the future, based on business development, they can add automated modules such as automatic loading and unloading, sorting and palletizing to reduce initial investment.   Fourth, accurately identify the target industry and customer group Not all factories are suitable for immediate purchase. It is necessary to find the right breakthrough point. Core target customers Sheet metal processing service center: They are the most ideal target users for composite machines because their business is to undertake various scattered and high-demand sheet metal parts. Equipment manufacturers specializing in multi-variety and small-batch production: such as those in industries like chassis and cabinets, elevators, food machinery, medical devices, environmental protection equipment, and intelligent warehousing equipment. Innovative enterprises in a period of rapid growth: They have high requirements for production flexibility and product iteration speed, and are willing to invest in advanced equipment to build core advantages. Potential market Replacement market: The target is those factories that are still using old-fashioned single-function equipment and have encountered production efficiency bottlenecks. Use the high efficiency of multifunctional machines to convince them to carry out "production upgrades".   if you have more ideas, please contact us!

In simple terms, laser cutting is not a "constant power consumption" operation. Its total power consumption mainly depends on the power of the laser itself, auxiliary equipment, and cutting process parameters.   I. Core Reason: Why do different materials have different power consumption? The essence of laser cutting is to use a high-energy-density laser beam to heat the material to its melting or vaporization point, while using an auxiliary gas to blow away the molten material, thereby forming a cut seam. Due to the different physical and chemical properties of various materials, the energy required to complete this process varies greatly. The absorption rate of materials Different materials have different absorption rates for lasers of different wavelengths. For instance, fiber lasers (with a wavelength of approximately 1.06μm) have a high absorption rate for metallic materials, but an extremely low absorption rate for certain non-metals, such as transparent plastics and glass. Materials with low absorption rates require higher laser power to initiate and maintain the cutting process, which means that the laser needs to output more energy and consume more electricity.   The melting point and vaporization point of the material Cutting metals (such as steel and aluminum) : It requires extremely high energy to melt them. Stainless steel is more difficult to cut than carbon steel because of its poor thermal conductivity and the viscosity of its molten material. Aluminum and copper, due to their high reflectivity and high thermal conductivity, require an extremely high initial power to penetrate, resulting in huge power consumption. Cutting non-metallic materials (such as acrylic, wood, and fabric) : CO2 lasers (with a wavelength of approximately 10.6μm) are typically used, as these materials have a good absorption rate at this wavelength. Their melting or ignition points are much lower than those of metals, so usually lower laser power is required and the total power consumption is also smaller.   Material thickness This is one of the most crucial factors. The thicker the material, the deeper the penetration depth required, and the laser needs to cut at a higher power and a slower speed. The energy consumed for cutting a 20mm thick steel plate is much higher than that for cutting a 1mm thick steel plate of the same type.   The role and consumption of auxiliary gases Oxygen: It is used when cutting carbon steel and undergoes an exothermic reaction with the metal. This part of the reaction heat helps with the cutting, thus reducing the demand for laser energy. Nitrogen: It is used when cutting stainless steel or aluminum, serving to protect and ensure high-purity cutting. It does not provide additional heat and relies entirely on laser energy to melt the material, thus requiring a higher laser power. At the same time, air compressors or nitrogen generators themselves are also major power consumers. Compressed air: An economical option, but its cooling effect may increase the loss of some laser energy. Ii. Analysis of Power Consumption Composition The total power consumption of a laser cutting machine comes from three major parts:   Laser: This is the main power-consuming unit. But it doesn't always operate at full power. During standby, perforation, low-speed cutting and high-speed cutting, its output power changes dynamically, and thus the power consumption is also different. Motion system: including servo motors, drivers, guide rails, etc., it is responsible for moving the laser head. The power consumption of this part is relatively stable. Auxiliary system Cooler: The greater the power, the higher the cooling demand, and the greater the power consumption of the cooler. Air compressor/air supply system: It provides clean and dry air for the optical path and gas path, with considerable power consumption. Exhaust fan/dust collector: It can extract the smoke and dust generated during cutting, with relatively high power. Numerical control system (CNC) : Low power consumption.     if you have more ideas, please contact us! Tel: +86 -18855551088 Email: Info@Accurl.com Whatsapp/Mobile: +86 -18855551088

Choosing the right CNC press brake machine can make a big difference in your production efficiency, bending accuracy, and overall profitability. With so many options on the market—each offering different features, tonnage capacities, and automation levels—it’s easy to feel overwhelmed. This guide will help you understand what really matters when selecting a CNC press brake, so you can make a smart investment that fits your business needs.   I. Core Considerations (Basis for Selection) 1. Processing Requirements Analysis (First ask yourself the question) Material properties Material: Is it mainly low-carbon steel, or stainless steel, aluminum, copper, etc.? The tensile strength of different materials varies, which affects the tonnage calculation. Plate thickness: What is the thickness range of the plates you bend most frequently? For example: 0.5mm - 6mm Sheet size: What are the maximum processing length and width? For example: 3m x 1.5m Product process requirements Bending Angle: Usually 90°. Is it necessary to bend obtuse angles, acute angles or complex shapes? Precision requirements: How high are the tolerance requirements for angles and dimensions? (For example: ±0.5° or ±0.1mm Production batch size: Is it a small batch with multiple varieties or a large batch with a single product? This is related to the demand for the degree of automation. The complexity of the parts: Is it necessary to have complex functions such as multi-axis movement of the rear stopper, winding, and dead edge pressing?   2. Key machine parameters (To pay attention to when reading the equipment manual Nominal pressure (tonnage) : This is the core capability of the bending machine. It must be calculated based on your thickest and hardest material. Simple calculation formula: P = (650 * S² * L)/V P: Required pressure (tons) S: Plate thickness (mm) L: Bending length (m) V: The width of the lower die slot (mm), usually taken as 8 times the thickness of the plate. For example, when bending a 3mm thick and 3-meter-long low-carbon steel plate using a 24mm wide lower die, the required pressure is approximately (650 * 3² * 3) / 24 ≈ 731 tons. Therefore, it is more reliable to choose a machine with a capacity of around 100 tons. It is recommended that the tonnage selected be 20% to 30% higher than the calculated value in case of emergency. The length of the workbench: It determines the maximum length of the sheet that can be bent. Please select based on the maximum size of your product. Common sizes include 2.5m, 3m, 4m, etc. Throat depth: It refers to the depth from the bending line to the inner side of the frame. This determines whether the folded side will hit the machine body when bending "box" type workpieces. The deeper the throat opening, the wider the processing range. Column spacing: The distance between the frames on both sides. The sheet to be bent must be able to be delivered to the rear stopper position through this spacing. This parameter is very important for processing workpieces with bends in the middle, such as "large door frames".   3. Numerical Control System and Automation Configuration (Determining Efficiency and ease of use) Brand of numerical control system International well-known brands: such as Accurl, have stable systems, powerful functions and good operation logic. Selection suggestion: Choose based on the operator's learning cost and budget. Whether the interface is intuitive and whether programming is convenient are important considerations. Y-axis (slider travel control) : The core axis that controls the bending depth (Angle). It is usually an electro-hydraulic servo system. The number of Y-axes determines whether the slider can remain parallel at different positions. For machines with long countertops, at least two Y-axes (one at each end) are required to ensure accuracy, and high-end models may have three or more. X-axis (forward and backward movement of the rear stopper) : Controls the bending position. The travel of the X-axis determines the minimum margin that can be bent. The rear stopper of high-end models is divided into multiple sections, which can avoid the already bent edges. R-axis (rear stopper moving up and down) : It is used to avoid complex workpieces or achieve special processes. Z-axis (left and right movement of the rear stopper) : Usually, the rear stopper beam is divided into two sections, left and right, which can move independently and is used for folding beveled or asymmetrical workpieces. Automated selection and matching (significantly enhancing efficiency) Deflection compensation: When the long table surface is bent, the slider and the table surface will undergo slight deformation due to force, resulting in inaccurate middle angles. The deflection compensation function (hydraulic or mechanical) can automatically counteract this deformation and is a key configuration to ensure the bending accuracy of long workpieces. It is strongly recommended to be equipped with it. Automatic mold changing: For working conditions where mold changes are frequent, it can greatly save preparation time. Robots or automatic loading and unloading: Suitable for large-scale and repetitive production, achieving "unmanned" workshops. Ii. Equipment Type Selection Upward movement type (arch frame type) : The slider moves downward in the upward direction. The mainstream type features good rigidity and high precision, and is suitable for the vast majority of application scenarios. Downward movement type: The worktable moves upward. The body has a low center of gravity, good stability and a small floor area, but the operating space is relatively cramped. Iii. On-site Verification and After-sales Service Sample testing: Be sure to bring your typical products and plates (especially the thickest, longest, and most demanding ones) to the manufacturer or existing customers for on-site testing. Check the accuracy and straightness of the bending Angle. Test the programming convenience of the numerical control system. Feel the noise and vibration when the machine is running. Inspect after-sales service: Ask the manufacturer if there are service outlets in your location, how long the response time is, and whether the supply of spare parts is sufficient. Good after-sales service can greatly reduce downtime losses.   if you have more ideas, please contact us! Tel: +86 -18855551088 Email: Info@Accurl.com Whatsapp/Mobile: +86 -18855551088

From digital drawings to perfect parts: Follow us to see how an Accurl bending machine completes complex sheet metal parts In the world of sheet metal processing, behind every complex chassis, bracket or casing, there is a transformation journey from flat to three-dimensional. Today, let's act as your guides and step into the workshop together, following an Accurl CNC bending machine to see how it gradually transforms an ordinary metal sheet into a precise three-dimensional part.   Protagonist: Accurl high-end series CNC bending machine   The first stop: Seamless arrival of data The journey begins in the digital world. The operator can easily import the pre-written CNC program into the self-developed ECU control system of the Accurl bending machine via local area network or USB. You will see: a clear 3D graphic simulation on the screen, previewing the entire bending process in advance. This can not only detect possible interference and errors, but also optimize the bending sequence to ensure absolute safety. This is the starting point of intelligent manufacturing.   Stop Two: Intelligent Preparation - The "Brain" Commands the "Hands and Feet" After the program is loaded, the "intelligence" of the device begins to manifest. You will see: The operator only needs to click once on the control console, and the automatic mold changing device at the back of the machine starts to operate, precisely moving the required upper and lower molds to the working position. Meanwhile, the hydraulic clamping deflection compensation system automatically adjusts the pressure according to the tonnage and length of this processing, ensuring that the bed remains absolutely straight even under force, laying a foundation for perfect precision.   The third stop: The Art and Science of the First Production Now, the operator places the first laser-cut sheet in position. You will see: The operator uses the Accurl high-precision rear stopper system in conjunction with the R-axis (rear stopper lifting) to quickly set the initial position. To handle the multiple bends of this complex part, the C-axis that comes standard with the Accurl bending machine begins to come into play. It controls the depth to which the upper die enters the lower die, that is, it controls the bending Angle. In programming, the system has automatically calculated and compensated for the rebound amount according to different material and Angle requirements. When non-90-degree bending is required, you will see that the X-axis (front and back of the rear stopper) and C-axis of the equipment configuration operate in coordination. By precisely controlling the stopper position and bending depth, complex bevel bending can be easily achieved. Overcoming complexity: On this bracket, there is a "Z" -shaped bend that requires two positioning. You will witness the precise movement of the rear stopper, with the sheet material skillfully flipped over. Under the guidance of the machine, the operation is smooth and accurate, without any jerks.   The fourth stop: Absolute Consistency in Repetition After the first piece passed the inspection perfectly, it entered the mass production stage. You will see: This is the moment when the Accurl bending machine truly demonstrates its value. Thanks to the outstanding rigidity of its integral welded fuselage, the frame undergoes almost zero deformation under continuous heavy loads. Result: The 1st piece, the 50th piece, the 500th piece... Every corner of each part maintains an astonishingly consistent Angle and size. This is the "copy and paste" precision brought by the rigid structure, which greatly reduces the quality inspection cost and the rate of non-conformity.   if you have more ideas, please contact us!

In the field of sheet metal processing, purchasing a bending machine is a long-term investment. When making a purchase, many people focus on tonnage, control systems and functions, but they overlook the most fundamental factor that determines the machine's lifespan and accuracy - the rigidity of the machine body. Just as the stability of a skyscraper depends on its foundation, the long-term performance and lifespan of a bending machine are entirely built on the "cornerstone" of the machine body's rigidity. Today, we will delve into why rigidity is so important and how Accurl's integral welded body can offer you unparalleled and lasting advantages.   I. Challenges under Pressure: Why Rigidity Is the "Lifeline" of Bending Machines? When the bending machine applies hundreds of tons of force to bend high-strength metals, this tremendous force also fiercely combats within the machine. If the rigidity of the machine body is insufficient, the following problems will occur, directly shortening the machine's lifespan: 1- Elastic Deformation and "arching" Effect: Phenomenon: Under a huge load, the bed and the slider will slightly bend like a bow, causing the middle part to be more "concave" than the two ends. This is what is called "flexible deformation". Consequence: It directly leads to a large Angle in the middle and a small Angle at both ends of the bent workpiece, forming a troublesome "boar-shaped bend", and completely losing control of the precision of long workpieces. 2- Metal Fatigue - The Invisible Structural Killer: Phenomenon: Each time the machine is bent, it undergoes a stress cycle. A frame with insufficient rigidity is like an iron wire that has been repeatedly bent and will develop micro-cracks at stress concentration points. Consequence: After millions of cycles, these micro-cracks gradually expand, eventually causing irreversible damage or even cracking to the fuselage structure, leading to the premature scrapping of the entire machine. This is the most fatal blow to the bending life. 3- Loosening at the connection and loss of precision: Phenomenon: The traditional split-type fuselage (connected by high-strength bolts) may experience slight loosening or creep at the connection points under long-term impact loads. Consequence: This loosening will disrupt the original parallelism between the slider and the worktable, resulting in inconsistent bending angles, poor verticality of the workpiece, and the need for frequent adjustments, leading to a sharp increase in maintenance costs.   Ii. Accurl's Solution: The Engineering Philosophy of Integral Welded Machine Bodies Facing these challenges, Accurl resolutely abandoned the lower-cost split structure and fully adopted a heavy-duty integral welded body. This is not merely a piling up of materials, but a commitment to ultimate precision and lasting reliability. Exploring Its lasting advantages Advantage One: Resist deformation and lay the foundation for precision Technical core: The integral body of Accurl is made of high-quality steel plates. The stress distribution is optimized through computer finite element analysis (FEA), and reinforcement design is carried out in key parts (such as the slider guide rail mounting surface and the cylinder mounting seat). The value we bring to you: Even under the maximum load, the deformation of the fuselage is controlled within an extremely small range. This provides a perfect platform for the Accurl standard hydraulic deflection compensation system to function. The two work together to ensure extraordinary straightness and angular consistency on the entire length of the workpiece. Advantage Two: Eliminate fatigue and achieve an extremely long service life Technical core: The integral welded structure eliminates the stress concentration points at the split connections. The stress is evenly distributed throughout the entire sturdy frame. After the welding is completed, the machine body will undergo stress relief annealing treatment to completely release internal stress, thereby greatly enhancing the fatigue strength. The value we bring to you: Your Accurl bending machine can withstand over ten million high-intensity working cycles while maintaining its main structure as stable as new. This means a longer service life of equipment, higher residual value of second-hand equipment, and lower depreciation cost per piece of processing. Advantage 3: Always parallel, with lower maintenance costs Technical core: As it is a complete rigid whole, there is no risk of loose connections. The slider and the worktable are connected through a precisely machined guide rail system and maintain permanent parallelism on a rigid reference. The value we bring to you: You don't have to worry about the precision issues caused by the loose body. The equipment can maintain the precision standards at the factory for a long time, reducing unplanned downtime and maintenance time, making your production smoother and more predictable. Advantage Four: A stable platform, unleashing the potential of automation Technical core: In the automated bending unit, the robot has extremely high requirements for positioning accuracy and repeatability accuracy. The integral rigid body of Accurl provides a stable platform that remains motionless. The value it brings to you: When you upgrade integrated robots or automatic mold changing systems in the future, the rigid body can ensure that the automation unit always operates at the highest efficiency, avoiding positioning errors or collision risks caused by minor changes in the main unit, and protecting your expensive investment in automation.   if you have more ideas, please contact us!

Through automation, intelligence and high-speed technologies, they bring revolutionary advantages over traditional punch presses or early CNC turret punch presses. These advantages are mainly reflected in aspects such as production efficiency, processing capacity, cost control and flexibility. 1.Extremely high production efficiency and speed This is the most direct manifestation of "efficiency". High-speed operation: The stamping frequency of modern high-efficiency turret punch presses is extremely high (up to 1,000 times per hour or even more), and the positioning speed of the X/Y axes is also extremely fast, significantly reducing the processing time of individual parts. Quick die changing: Most high-efficiency turret punch presses are equipped with an Auto-Tool Indexing function. The die station on the turret can rotate automatically, quickly moving the required dies to the stamping position, eliminating the downtime caused by manual die changing. Some high-end models even feature multi-station turrets (such as 20-station, 30-station or more), allowing for the installation of more molds to handle complex parts without the need for mold changes in the middle. Reduce non-processing time: The efficient numerical control system (CNC) optimizes the stamping path, reducing the idle travel time of the punch on the sheet metal.   2. Strong complex processing capabilities One-time molding: Multiple processes such as punching, stretching, forming, embossing, tapping, louver, and ribbing can be completed in one clamping. A complex part may only require one set of programs to complete and does not need to be transferred to other machine tools for secondary processing. Special molds can be used: Multi-Tool or Auto-Indexing Tool can be equipped. A mold station contains multiple small molds that can be automatically selected for use, greatly expanding processing capacity without occupying additional workstations. Repositioning technology (Reresting) : for parts with dimensions larger than the turret spacing, the machine tool can hold the sheet metal, move it and then reposition it to achieve "step punching" processing, thereby machining holes and contours larger than the theoretical stroke of the machine.   3. Outstanding precision and consistency High-precision positioning: Utilizing precise servo motors and linear guides, the positioning accuracy of the punch in the X and Y directions is extremely high (up to ±0.1mm or higher), ensuring that the position of each hole and contour is accurate without error. Eliminate human error: The entire processing procedure is controlled by CNC programs and is fully automated. As long as the program is correct, each processed part will be exactly the same, with stable and reliable quality, making it very suitable for mass production.   4. Significant automation and flexibility Easy to integrate with automated units: High-efficiency turret punch presses are the ideal core for building flexible manufacturing units (FMCS) or automated production lines. It can be easily connected to automatic loaders (Loader), unloaders (Unloader) and stackers (Stacker), achieving unmanned production (Lights-Out Manufacturing) for several hours, significantly reducing labor costs and improving equipment utilization. Quick task conversion: When changing processed products, simply call the new processing program in the CNC system without the need for complex mechanical adjustments. This "soft switch" makes the production of small batches and multiple varieties very economical and efficient.   5. Reduce overall operating costs (TCO) Labor saving: With a high degree of automation, one operator can manage multiple devices simultaneously, reducing the reliance on skilled workers and labor costs. Reduce material waste: CNC systems usually come with automatic Nesting software, which can optimize the layout of parts on the sheet, maximize material utilization, and reduce waste. Improve equipment utilization: Due to its high speed, short mold changing time, and the ability to operate automatically, the actual effective working time of the equipment is reduced. Energy conservation: Compared with large laser cutting machines, turret punch presses usually consume less energy when processing thin plates with dense hole arrays.   6. Improve the working environment and safety High safety: Modern equipment is equipped with multiple safety protections, such as light curtains, safety fences, interlock devices, etc., to ensure that operators are isolated from high-speed moving components. Low noise and pollution: Compared with traditional stamping, high-efficiency turret punch presses usually operate in closed or semi-closed environments, resulting in less noise. At the same time, unlike laser cutting, it does not produce smoke and dust, making the working environment cleaner.   if you have more ideas, please contact us!

I. Core Working Principle (Interaction between Laser and Material) 1. Energy Absorption and conversion The laser generates an extremely fine, highly bright and monochromatic laser beam. This laser beam is transmitted through optical fibers to the handheld welding torch. After collimation and focusing, it irradiates the surface of the metal workpiece. Metallic materials can absorb the energy of lasers (especially in the infrared band, such as 1064nm, for which metals have a relatively high absorption rate), and instantly convert light energy into thermal energy. - Melting and molten pool formation: In the tiny area irradiated by the laser (the focal diameter is usually only a few tenths of a millimeter), the energy is highly concentrated, the temperature rises sharply, and the metal melts or even vaporizes rapidly. As the welding torch moves, the laser beam moves synchronously, and the molten metal area also moves and cools and solidifies at the rear. This continuously flowing area of liquid metal is called the "molten pool". - Weld formation: The metal at the front end of the molten pool keeps melting, while the metal at the tail end keeps cooling and solidifying, thus forming a continuous and uniform weld seam. Due to the highly concentrated laser energy, the heating and cooling speeds are extremely fast, thus the heat-affected zone is very small and the workpiece deformation is also minimal. Ii. System Composition and Collaborative Work A complete handheld laser welding machine is not merely a gun; it is a system mainly consisting of: 1. Laser: The "heart" of the system, usually a fiber laser is adopted. Because of its high efficiency, good beam quality, relatively small size and maintenance-free nature, it is very suitable for handheld applications. The power range is usually between 1000W and 2000W, and it is suitable for welding materials of various thicknesses. 2. Cooling system: When the laser is in operation, it generates a large amount of heat and requires a matching chiller for cooling to ensure the stable and long-term operation of the laser. 3. Control system: The "brain" of the machine, integrated within the main unit. It is used to set and adjust parameters such as laser power, frequency, and duty cycle, and monitor the operational status of the entire system. 4. Handheld welding gun: This is a key component for achieving "handheld" operation. It contains: - Collimating mirror: Converts the divergent laser emitted from the optical fiber into parallel light. - Focusing mirror: Focuses the parallel laser beam onto the surface of the workpiece to form a high-energy-density spot. - Protect the lenses: Prevent spatter generated during welding from contaminating and damaging the internal optical lenses. - Indicator light: Usually a red LED or low-power laser, it is used to indicate the position of the current laser focus, facilitating the operator's aiming. - Wire feeding system (optional) : Many handheld welding torches are integrated with or equipped with external wire feeding machines, which automatically and precisely feed the welding wire into the molten pool when it is necessary to add welding wire during welding. - Protective switch: Light will only come out when the switch is pressed to ensure safety. 5. Supporting workbench: including platforms for placing workpieces, fixtures, etc.   f you have more ideas, please contact us!

In today’s manufacturing industry, fiber laser cutting machines have become an essential tool for metal processing. Among them, the 2kW fiber laser cutting machine stands out for its balance of power, efficiency, and cost-effectiveness. But how exactly does it work, and why do so many workshops rely on it?   1. Principle of Laser Generation   Light Source: A fiber optic cable doped with ytterbium or other rare earth elements is used as the gain medium. A semiconductor pump source (such as a diode laser) excites the rare earth ions within the fiber, causing high-energy level transitions and releasing light of a specific wavelength (typically near-infrared light at 1070–1080 nm). Fiber Amplifier:   The laser is repeatedly reflected and amplified within the flexible fiber, forming a high-power density, high-beam-quality continuous or pulsed laser beam.   2. Laser Transmission and Focusing   Fiber Transmission:   The laser is transmitted through the flexible fiber to the cutting head, eliminating the need for complex mirror systems (unlike CO₂ lasers), resulting in minimal energy loss (<5%) and suitability for long-distance transmission. Focusing System:   Collimating lenses and focusing lenses (typically aspherical lenses) within the cutting head focus the laser beam into an extremely small spot (diameter approximately 0.01–0.1 mm), achieving power densities of 10⁶–10⁸ W/cm².   3. Material Cutting Mechanism Main physical processes in metal cutting: Absorption and Heating: Metal surfaces have high absorption rates for fiber laser wavelengths (especially for highly reflective materials like copper and aluminum; anti-reflective coatings can further enhance efficiency). Light energy is absorbed by electrons and converted into thermal energy, causing the local temperature of the material to instantly rise to its melting point or boiling point (e.g., approximately 1500°C for steel). Melting and vaporization:   Melting cutting (suitable for carbon steel, stainless steel): Laser energy melts the material, and auxiliary gases (such as nitrogen, oxygen) blow away the molten metal.   Sublimation cutting (suitable for thin sheets or high-precision requirements): The laser directly vaporizes the material without requiring auxiliary gases (such as extremely thin metals or non-metals). Role of auxiliary gases:   Oxygen (O₂): Reacts exothermically with molten metal (oxidation), accelerating cutting and improving the quality of carbon steel cut surfaces, but may produce an oxide layer.   Nitrogen (N₂): Inert protection, preventing oxidation, suitable for materials requiring clean cuts such as stainless steel and aluminum.   Formation of the cut seam:   The laser beam moves relative to the material (controlled by a CNC system) to form a continuous cut seam. Dynamic adjustment of the focal position (e.g., automatic focusing cutting head) to accommodate different material thicknesses.   4. CNC System and Motion Control CNC Control: Pre-set cutting paths (e.g., DXF files) are converted by a computer into mechanical motion commands, driving servo motors to control the movement of the cutting head or worktable (X/Y/Z axes). Dynamic Precision:   High-precision guideways and linear motors ensure positioning accuracy (±0.05mm) at cutting speeds of up to 50m/min.     5. Advantages and Limitations of 2kW Power   Advantages:   Can cut thicker materials (e.g., carbon steel ≤20mm, stainless steel ≤12mm, aluminum ≤10mm).   Faster speed (30%–50% faster than a 1kW laser machine). Lower energy consumption (electro-optical conversion efficiency of 30%–50%, significantly higher than CO₂ lasers at 10%).   Limitations:   Special processing is required for highly reflective materials (e.g., copper, gold) (e.g., adjusting pulse frequency).   Extremely thick materials (e.g., carbon steel >25mm) may require multiple cuts or alternative methods such as plasma/flame cutting.   6. Key components and technologies   Fiber laser: 2kW single-mode or multi-mode fiber lasers from brands such as IPG and SPI.   Cutting head: Brands such as Precitec and Raytools, including protective lenses, gas nozzles, and capacitive height adjustment systems.   Cooling system: Water-cooled units maintain stable laser temperature (±1°C).   Dust removal system: Ventilation or filtration devices handle cutting fumes.   7. Typical Application Scenarios   Industries: Sheet metal processing, automotive parts, aerospace, electronic enclosures, etc.   Materials: Carbon steel, stainless steel, aluminum alloy, brass, titanium alloy, etc.   Processing types: Flat cutting, drilling, and irregular contour cutting. Translated with DeepL.com (free version) Summary： The 2kW fiber laser cutting machine uses high-energy fiber laser beams, precision optical systems, and CNC technology to achieve efficient, high-precision cutting of metal materials. Its core advantages lie in its high power density, low energy consumption, and low maintenance costs, making it particularly suitable for processing medium-thickness metal plates. In practical applications, the power, focal position, and auxiliary gas type must be adjusted according to the material characteristics to optimize cutting quality.   If you have more ideas, please contact us!

When operating a press brake, corner bending is one of the most challenging processes. Compared with straight-line bending, corners place higher demands on precision, tooling, and operator experience. If not handled correctly, several problems may occur that affect both product quality and production efficiency.   1. Angle deviation (inaccurate Angle） Reason: Improper mold selection (such as the V-groove width not matching the material thickness). The excessive opening of the lower die leads to an increase in springback. Insufficient pressure or too fast bending speed. Material properties (such as obvious rebound of stainless steel and high-carbon steel). Solution: Adjust the pressure and compensation Angle (correct the rebound through trial folding). Select an appropriate mold and reduce the bending speed to increase plastic deformation. 2. Bending dimensional error (length or position deviation) Reason: Inaccurate positioning of the back gauge or mechanical wear. The boards are placed unevenly or the reference surfaces are not close together. Programming data input errors (such as bending sequence, size). Solution: Calibrate the rear stopper and check the accuracy of the servo system. Use laser detection or clamp-assisted positioning.   3. The bent line is twisted or uneven The reason is that the burrs on the edge of the sheet were not treated, resulting in uneven stress during bending. Mold wear or misalignment of the upper and lower molds (parallelism deviation). Internal stress of materials (such as unannealed cold-rolled plates). Solution: Deburr and ensure the board is smooth. Adjust the parallelism of the mold and replace it if necessary.   4. Indentations or scratches on the surface of the workpiece Reason: There are impurities or damages on the surface of the mold. The protective film of the material was not removed or the mold was not cleaned adequately. Excessive bending pressure causes metal adhesion. Solution: Clean the mold and use a dedicated polishing mold or PE protective film. Adjust the pressure or switch to a soft mold (such as polyurethane).   5. Springback Reason: The material has a high elastic modulus (such as aluminum and stainless steel). The bending radius is too large or the Angle is too small. Solution: Adopt the compensation method (excessive bending). Use a mold with correction function or add a flattening step.   6. Bending cracks or fractures Reason: Poor ductility of the material (such as hard aluminum alloy, high carbon steel). The bending direction is parallel to the rolling direction of the material. The bending radius is too small (lower than the minimum bending radius). Solution: Increase the bending radius or anneal the material. Adjust the bending direction (perpendicular to the rolling direction).   7. Damage to equipment or molds Reason: Overloading bending (such as thickness exceeding the die's load-bearing range). The mold collided or was not fixed correctly. Solution: Operate strictly in accordance with the equipment tonnage and mold specifications. Regularly check the tightness of the mold.   8. Cumulative error of multiple bends Reason: Multiple positioning causes the reference to shift. The bending sequence is unreasonable (for example, bending at a large Angle first and then interfering with a small Angle). Solution: Optimize the bending sequence (from inside to outside, from complex to simple). Use multi-axis rear stoppers or robot-assisted positioning.   9. Warping or deformation of the sheet Reason: Uneven distribution of bending force (such as no support in the middle of long plates). Release of residual stress in materials. Solution: Add support blocks or bend in multiple steps. Select the material after stress release. 10. Operational safety issues Risk: Hand pinching (near the mold area). The sheet rebounds or slips off. Protection: Use safety devices such as gratings and two-hand start buttons. Train operators to standardize procedures.   If you have more ideas, please contact us!
