  • Why is the CNC turret punch press the intelligent heart of modern sheet metal processing?
    Why is the CNC turret punch press the intelligent heart of modern sheet metal processing? May 29, 2025
    I. Core Technology: The unique design principle of the turret punch press The core of a CNC turret punch press lies in its turret structure - a rotating tool magazine that can accommodate dozens of sets of molds. Unlike traditional single-punch presses, the turret design enables automatic die switching through program control, allowing the equipment to complete multiple processes such as punching, forming, and stretching in a single clamping. The turret is usually divided into two layers, with the upper die installed on the upper layer and the lower die fixed on the lower layer. Through precise synchronous rotation and positioning, the perfect alignment of the dies at the moment of stamping is ensured. The precision servo drive system is the nerve center of modern turret punch presses. It controls the high-speed and precise positioning of the sheet in the X-Y plane, the Z-axis movement trajectory of the punch, and the rotation Angle of the turret. The high-dynamic servo motor, in combination with the linear guide rail, enables the metal sheet to move at a speed exceeding 100 meters per minute, while maintaining the positioning accuracy within ±0.1mm. This combination of speed and precision is beyond the reach of manual operation or traditional machinery. Safety design is another major highlight of the turret punch press. Modern equipment adopts the "human-machine separation" principle - when the equipment is in operation, the operator stays away from the working area, and the equipment automatically stops when the operator approaches. In combination with the light curtain protection and the two-hand start button, the equipment achieves the intrinsic safety of "human-powered machine stops and motorized human-powered machine stops", completely eliminating the risk of hand injury caused by traditional punch presses. Ii. Technological Innovation: Intelligent control systems empower efficient production The innovation of touch interaction interfaces has greatly enhanced operational efficiency. The new generation of turret punch press adopts a 21.5-inch FHD full high-definition vertical screen and supports 10-point capacitive touch control. Operators can operate smoothly even when wearing gloves. The 178° full-view screen ensures that the processing status can be clearly observed from all angles. The closed rigid chassis design effectively resists the ubiquitous dust and oil stains in the metal processing environment, ensuring the long-term stable operation of the electronic system. The introduction of adaptive control technology has endowed the turret punch press with the ability to "think". Similar to the ACM adaptive monitoring system of OMAT Company, it can collect the spindle load data in real time and dynamically adjust the processing parameters. When abnormal vibration or sudden load changes are detected, the system can automatically slow down or shut down to avoid costly mold damage. Practical application data shows that this technology can save approximately 38% of the time for contour processing, 34% for slot hole processing, and extend the mold life by up to 40%. The modular programming platform has significantly lowered the technical threshold. Modern turret press control systems offer a graphical programming interface. Operators only need to import CAD drawings, and the system can automatically generate and optimize the stamping path. For complex and irregular-shaped holes, the software will automatically decompose the continuous contour into a series of small line segments and achieve this through high-speed step punching. This "what you see is what you get" programming approach enables operators without a mechanical background to quickly master the use of the equipment, providing an efficient employment channel for new immigrants and technology transition personnel. Iii. Automation Integration: Building an unmanned sheet metal factory The robot collaborative system has greatly enhanced the capabilities of the turret punch press. Through an integrated solution similar to Siemens' Sinumerik Run My Robot, industrial robots can be directly controlled by the CNC system to achieve full-process automation of automatic sheet material loading, finished product stacking and mold replacement.   This deep integration not only reduces the hardware configuration requirements, but also optimizes the robot's motion trajectory accuracy through a unified data flow, making the entire working unit coordinated as one.   The combination of the automatic mold changing system (ATC) and the automatic pallet exchange system (APC) has created a continuous production environment. When the equipment is processing the current workpiece, the robot has already clamped the next sheet in the preparation area. When special molds are required, the turret automatically rotates to the target workstation, and the entire process only takes 2 to 3 seconds. This seamless connection has raised the equipment utilization rate from the traditional 50-60% to over 85%, truly achieving a continuous production mode of "factory with lights off". Iv. Industry Application and Economic Value: The Core Carrier of sheet metal processing The application scope of CNC turret punch presses is astonishing: from 1mm thick electronic chassis panels to 12mm thick protective plates for construction machinery, from stainless steel kitchen equipment to aluminum alloy elevator decorations, its processing capacity covers almost all metal plates that require holes and shapes.   Factories equipped with turret punch presses are often simultaneously configured with CNC laser cutting machines and CNC bending machines, forming a complete sheet metal processing production line. The salary level in the industry confirms its technical value. In North American manufacturing, the starting salary for technicians operating fully automatic turret punch presses can reach $18 per hour, and for junior positions, it is no less than $15 per hour. The salaries offered by domestic high-end sheet metal enterprises for skilled turret punch press programming operators are also significantly higher than those for ordinary positions, which reflects the market's urgent demand for compound sheet metal technical talents. V. Future Trends: The Integration of Digitalization and Flexibility Digital twin technology is transforming the operation mode of turret punch presses. By fully simulating the stamping process in a virtual environment, engineers can optimize die selection, sheet metal layout and stamping sequence before actual production. Systems such as hyperMILL® VIRTUAL Machining can generate digital twins of real machine tools. Collision checking and motion optimization are completed in the virtual space to ensure the success of actual processing in one attempt. Users can upgrade from small format to large format and expand from thin plate processing to thick plate processing without replacing the entire machine, significantly enhancing the return on investment. Edge computing and the Internet of Things endow devices with predictive maintenance capabilities. By real-time monitoring of the main motor current, the positioning accuracy of the turret and the impact waveform of the punch, the system can provide early warnings of potential faults such as guide rail wear and mold fatigue. This shift from "regular maintenance" to "on-demand maintenance" has elevated the availability of equipment to a new level. If you have more ideas, please contact us!

  • CNC Punching Machine Capabilities: What Thickness Can It Really Handle?
    CNC Punching Machine Capabilities: What Thickness Can It Really Handle? Apr 30, 2025
    The processing capacity of a CNC punching machine is influenced by multiple factors such as material type, machine tool model, mold design and process parameters. The following is the thickness range and key points of CNC punching machine processing sorted out after comprehensive search results: 1.The conventional processing thickness of a common CNC punching machine - Low-carbon steel: Usually 0.8 to 3.5mm, with a recommended thickness of less than 3.5mm; If special processes (such as roof cutting or concave cutting design) are adopted, it can be processed to 6mm. Stainless steel: The recommended thickness is 0.8 to 2.5mm. However, due to the rapid tool wear and high scrap rate, CNC punching machines are generally not preferred for processing. - Aluminum/copper plates: The recommended thickness is 0.8 to 4.0mm. However, it should be noted that soft materials are prone to sticking to the mold, so coating punches should be used or the mold gap should be adjusted.   2. The processing capacity of the special CNC punching machine for thick plates Carbon steel plate: Some dedicated models for thick plates (such as the NCPH series) can process up to 16mm in thickness and have a nominal stamping force of 3150KN, making them suitable for processing thick plates such as automotive longitudinal beams. - Other materials: such as copper, aluminum and other soft metals. By optimizing the mold gap (increasing by 5% to 20%) and tonnage calculation, it can be processed to 12.7mm (such as 1/2 inch).   3. Key factors affecting processing thickness Tonnage requirement: For punching thick materials, a higher tonnage is needed. The calculation formula is: land inches × material thickness × shear factor ×25. For example, a hole with a diameter of 2 inches and a thickness of 6.35mm requires more than 39 tons of force, which exceeds the capacity of ordinary machine tools. - Mold design: - Mold clearance: For thick materials, the mold clearance should be increased (for example, for low-carbon steel, it should be adjusted from 15% to 20%) to reduce demolding issues. - Punch material: Powder metallurgy punches are recommended to enhance impact resistance, and a coating is added to reduce the risk of soft materials adhering to the mold. - Maintenance and processing: Blunt tools will increase the required tonnage and need frequent grinding to extend their service life; Shearing designs (such as roof shears) can reduce tonnage requirements.   4. Special models and process expansion - Fully automatic CNC punching machines (such as DHSKC-Q series) : The maximum processing thickness is 6mm, supporting complex shapes such as round holes and special-shaped holes, suitable for industries like electronics and medical devices. - Turret punch press (such as COMA-567) : Optimized for thin plates, suitable for carbon steel plates under 2mm, with limited processing capacity for thick plates. Laser cutting alternatives: For ultra-thick materials (such as ≥16mm) or high-precision requirements, laser cutting is superior, but it is more costly and not suitable for materials with fast heat conduction, such as aluminum and copper.   5. Practical application suggestions - Material selection: Prioritize materials such as low-carbon steel and aluminum plates that are easy to machine. For stainless steel, carefully assess the cost of the cutting tools. - Equipment selection: For thick plate processing, dedicated models (such as the 16mm thick plate CNC punching machine from Qingdao Kelida) should be selected, and they should be equipped with high-precision servo systems and ball screws. - Process optimization: Use multi-station molds and automatic programming software (such as CAD to directly generate codes) to enhance efficiency. At the same time, pay attention to the design of hole spacing to avoid mold strength issues.   Summary Ordinary CNC punching machines are suitable for low-carbon steel plates of 3.5mm or less or aluminum/copper plates of 4mm or less. The special model for thick plates can be extended to 16mm carbon steel. The actual processing should be combined with the material properties, equipment capabilities and process adjustments. When necessary, laser cutting or cold stamping dies can be used as supplementary processing. If you have more ideas, please contact us!

  • Accurl Press Brake Setup & Installation Guide
    Accurl Press Brake Setup & Installation Guide Mar 28, 2025
    The bending machine is the most expensive to install. Analytical sketch The operator must be fully familiar with its components. If the part has already been manufactured, it may not be necessary to modify the design, but ultimately the operator must understand that: Material type and density. Flange dimensions and tolerances. Necessary Angle and Angle tolerances. Angle inside the arc. Blank size. In the absence of any of these data, supervisors will need to make educated assumptions. The part is now at risk of being inaccurate. An important initial step is to obtain detailed drawings.   Tool selection The sketch is used to select the tool. There are several options for you to choose from: air bending, bottom bending, coinage or custom use. For example, if the layout requires a bottom tool and the internal arc length is equal to the metal density. For that particular type of machine, you should use a tool with at least the same precision as the tool manufacturer recommends. No matter how accurately the bending machine is installed, worn equipment will not produce the right product.   Calculated tonnage It should be easy for the operator to estimate the tonnage required. Regarding air bending, there seem to be tonnage charts available. A reasonable calculation for bottom bending is nearly three times the air bending tonnage. Stamping requires about eight times the bending tonnage of air. The supplier will provide tonnage estimates for custom application tools. Do not attempt to bend until you have determined the tonnage required and compared it to the tonnage provided.   Select a bending machine If you have only one press in your workshop, you can skip this step. If you have more than one press, make sure that the press you choose is best for the task at hand. The center of the press has a tonnage per inch limit. Multiply the length of the side panels by 0.6 to find the tonnage per inch of the press, then start dividing your estimate by the tonnage of the machine. For items 12 inches wide, the maximum tonnage of the machine center should not be higher than 25 tons. 25 tons over 12 inches will produce compression overload. This is a bad decision because it could permanently damage the ram. When using tonnage control (manual and CNC), be sure to use only the amount required for the torsion parts and do not exceed the tonnage threshold in the middle. Also, keep in mind that overload of the bender is only allowed when the bottom is compacted, cast, or air bent with dedicated tools. Select tool location If the required tonnage exceeds the concentrated weight limit at the center of the system, you may be able to complete the task off-center. However, you should first verify that the bender supplier allows eccentric loading to proceed. Eccentric work is acceptable as long as you follow the manufacturer's guidelines.

  • Is Nitrogen or Oxygen Better for Laser Cutting?
    Is Nitrogen or Oxygen Better for Laser Cutting? Mar 21, 2025
    In laser cutting, the choice of nitrogen (N₂) and oxygen (O₂) mainly depends on the type of material to be cut, cutting quality requirements, and cost effectiveness. The following is a comparative analysis of the two and suggestions for applicable scenarios:   The applicability of nitrogen (N₂) Advantages: 1. No oxidation cutting - Applicable materials: stainless steel, aluminum, titanium alloy, brass and other non-ferrous metals or high reflective materials. - Effect: Nitrogen as an inert gas can prevent the oxidation reaction between the material and oxygen during the cutting process, and the edge of the incision is smooth and no oxide layer, reducing the need for subsequent grinding or painting.   2. High surface quality - Clean cutting surface, suitable for precision machining with strict surface requirements (such as medical equipment, electronic product parts).   3. Avoid slag residue - High purity nitrogen (more than 99.9%) can effectively blow molten metal under high pressure, reducing slag adhesion.   Cons: 1. High cost - Large nitrogen consumption (high pressure, high flow), and high purity nitrogen is expensive, especially for thick plate cutting costs significantly increased. 2. The cutting speed is slow - No exothermic reaction, completely dependent on laser energy to melt the material, cutting speed is lower than oxygen assisted cutting.   Second, the applicability of oxygen (O2) Advantages: 1. Exothermic reaction accelerates cutting - Applicable material: carbon steel (such as low carbon steel, medium carbon steel) - Principle: Oxygen reacts with high temperature metal oxidation (Fe + O₂ → FeO + heat), releasing additional heat energy and significantly increasing cutting speed (30% to 50% faster than nitrogen).   2. Good economy - Low oxygen cost, and due to reaction heat release can reduce laser power requirements, suitable for high-volume carbon steel processing.   3. Advantages of thick plate cutting - For thick carbon steel plates (such as more than 20mm), oxygen assistance can effectively penetrate and maintain cutting efficiency.   Cons: 1. Oxidation problem - The edge of the cut will form an oxide layer (black or yellow), requiring subsequent treatment (such as grinding, painting), affecting the surface quality. 2. Not applicable to non-ferrous metals - Aluminum, stainless steel and other materials cut in oxygen tend to produce high melting point oxides (such as Al₂O₃), resulting in poor cutting quality or even failure. Iii. Other precautions 1. Gas purity requirements - Nitrogen: ≥99.9% (recommended for stainless steel cutting more than 99.99%). - Oxygen: purity ≥99.5% to avoid impurities affecting reaction efficiency. 2. Gas pressure and flow Nitrogen usually requires a higher pressure (e.g., 20 to 30Bar) to blow away the melt. - Low oxygen pressure (e.g. 10 to 15Bar), but subject to material thickness adjustment. 3. Alternatives - Air cutting: the lowest cost, but only suitable for thin carbon steel or the quality of the scene is not high, the incision oxidation is obvious. - Mixed gas: Some scenarios use nitrogen-oxygen mixture (such as cutting galvanized sheet), balancing speed and oxidation problems. In SUMMARY: - Nitrogen: If the cutting material is non-ferrous metal such as stainless steel or aluminum, or the incision finish is required (such as appearance parts and precision parts). Choose oxygen: if cutting carbon steel and pursuing efficiency and cost advantages, especially suitable for thick plate processing. - Trade-off between economy and quality: nitrogen is preferred for high value-added products, oxygen is preferred for high-volume carbon steel processing. Flexible gas selection according to specific needs can significantly improve laser cutting efficiency and control costs.   If you have more ideas, please contact us!

  • What materials can a fiber laser cut?
    What materials can a fiber laser cut? Mar 07, 2025
    Fiber laser cutting machine with its high power density, high precision and high efficiency characteristics, widely used in the processing of a variety of materials, especially good at metal cutting. The following is the main material classification and precautions for its application: First, metal materials (main application areas) 1. Carbon steel (Mild steel) - Excellent cutting effect, can handle a wide range of thickness (usually up to 30mm, high power models up to 50mm or more) - Smooth incision, controllable oxidation layer, suitable for automobile manufacturing, mechanical processing, etc. 2. Stainless Steel - Suitable for thin sheet to medium thick plate (common thickness 0.5~20mm), oxidation cutting or nitrogen protected cutting (to avoid oxidation). - Commonly used in food machinery, medical equipment and other industries with high surface quality requirements. 3. Aluminum and aluminum alloys - Cutting challenges: High reflectivity can cause laser damage, requiring the use of anti-reflective coatings or dedicated models. - The applicable thickness is usually thin (≤10mm), and it is widely used in aviation and electronics industries. 4. Copper (pure copper, brass, bronze) - High reflectivity, high power laser (≥2000W) and nitrogen assisted cutting. - Commonly used for precision components such as electrical components and radiators. 5. Other metals Titanium alloy: common in the aerospace field, requires inert gas protection to prevent oxidation. Nickel alloys (such as Inconel) : high temperature resistant materials, suitable for energy and chemical equipment. - Galvanized sheet: commonly used in the construction industry, pay attention to zinc vapor emissions when cutting. Two. Non-metallic materials (limited application) The fiber laser wavelength (1.06μm) has a low absorption rate for non-metals, and it is generally not recommended to cut the following materials, but there are still individual cases: 1. Some plastics: such as ABS, acrylic (the edge may be carbonized), need low power, high-speed cutting. 2. Composite material: carbon fiber reinforced material (CFRP) can be cut, but it is easy to layer, requiring fine parameter adjustment. 3. Precautions: - Cutting non-metals may produce toxic gases (such as chlorine), requiring strict ventilation. - Non-metallic cutting is more recommended CO2 laser (wavelength 10.6μm, higher absorption rate).     Third, not applicable materials  1. Wood, leather, cloth: easy to burn, serious edge coking, low efficiency. 2. Glass and ceramics: brittle materials, laser thermal stress is easy to lead to fragmentation. 3. When high reflective materials are not processed: such as mirror copper and aluminum, special processes are required to prevent damage to the laser head. Four. Key influencing factors 1. Laser power: High power (such as 6000W or more) can improve cutting thickness and efficiency. 2. Auxiliary gas: - Oxygen: enhanced carbon steel cutting ability (oxidation reaction heat release). - Nitrogen: used for non-oxidation cutting of stainless steel and aluminum, the gas purity is high. 3. Material surface state: Oil, coating or rust may affect the cutting quality.   Sum up The core advantage of fiber laser cutting machine is metal processing, especially the efficient cutting of stainless steel and carbon steel; Specific configuration is required for highly reflective metals (copper, aluminum); Non-metal cutting capacity is limited, need to choose carefully. In practical applications, parameters should be adjusted according to material characteristics and safety specifications should be strictly observed.
