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!

I. Mechanical Injuries (the most common and diverse forms) The upper and lower dies squeeze and hurt the hand Dangerous scenario: When positioning or picking up and placing small workpieces after adjustment, if the hand accidentally enters the closed area of the mold (there is a risk of cutting if the stroke is ≥10mm). Typical case: Improper gesture when bending small parts (Figure 2), the finger was caught between the upper die and the workpiece, resulting in a comminuted fracture. Protection: Mandatory use of photoelectric protection devices (light curtains), automatic shutdown when hands enter the hazardous area. Physical isolation barriers are installed in the mold area. 2. Workpiece impact and dropping Risk of double-person operation: When bending large items, they need to be lifted in coordination. If the workpiece becomes unstable and falls, it may hit the foot or head (Figure 1). The burrs on the edge scratched the arm. Material stacking risk: The workpiece to be processed is stacked too high and overturns, or is scratched by sharp corners when turned around. Protection: Heavy items require hoisting equipment. Wear anti-crush shoes and safety helmets; The workpiece is reprocessed after deburring. 3. Accidents during mold loading and unloading Loose fastening bolts of the upper mold cause the mold to fall, or the lower mold is not padded with support wood, resulting in a rolling accident. Protection: Operate strictly after locking the machine (LOTO program); Anti-fall brackets are designed in the mold installation area. Ii. Electrical Injuries (with the highest fatality rate) 1. Electrical leakage caused by illegal renovation Non-standard circuit modification (such as direct connection of the neutral wire to the PE terminal) causes the equipment casing to carry a 220V voltage, significantly increasing the risk of electric shock. Protection: Comply with the national standard "single power connection" principle; A third-party electrical safety certification is required after the renovation. 2. Aging of circuits and short circuits Cable damage and negative pressure ventilation in the electrical cabinet drawing in cutting fluid/dust (as shown in the illustration) can cause an internal short circuit or fire in the electrical cabinet. Protection: The protection grade of the electrical cabinet is ≥IP54; Inspect the insulation condition of the lines every day; Leakage protection devices should be installed for wet zone operations. 3. Grounding failure of the equipment Poor grounding causes the metal frame to become electrified. During the rainy season or in damp workshops, it is easy to form an electric shock circuit. Protection: Test the grounding resistance (≤4Ω) weekly; Insulating rubber pads are laid on the operation console.   Iii. Parameter Errors and Mold Out-of-control 1. The pressure setting exceeds the limit The pressure suddenly increased beyond the limit value of the mold (such as setting a 300T parameter for a 200T press), causing the mold to crack and fragments to fly. Protection: Hierarchical management of parameter permissions; The system has a built-in pressure-mold matching database. 2. Overheating of the mold and lack of maintenance Continuous bending of thick stainless steel plates causes the mold temperature to rise by more than 150℃, and the annealing deformation of the material leads to mold jamming. Protection: Early warning by mold temperature control sensor; Cool and lubricate every 2 hours.   Iv. Human and Environmental Factors 1. Collaboration failure The foot switch operated by two people is not synchronized: When one person steps on it, the other is still adjusting the workpiece, causing the workpiece to shift and injure the lower jaw (Figure 3). Protection: Enable the "Double Confirmation" startup program (two people press keys simultaneously); Train collaborative gesture commands. 2. Fatigue and distraction When working in consecutive shifts for more than 4 hours, the rate of accidental button touches increases by 40%. Wearing gloves when handling small items makes it easy to get caught in. Protection: Mandatory rotational rest every 90 minutes; Do not use gloves when bending small items. 3. Environmental hazards After slipping due to the oil stains on the ground, my hand fell into the mold area. Insufficient light misjudges the positioning of the workpiece. Protection: 5S management (especially immediate cleaning of oil stains); The illuminance in the operation area is ≥300 lux. Summary： The safety of bending machines requires equal emphasis on technical protection (hardware) and behavioral management (software). Urgent priority: Photoelectric protection + electrical compliance transformation to avoid immediate life-threatening risks; Long-term management: Each shift's "Hazard Source Board" (Figure 4) indicates the risk points of the day, and combines the SHARP analysis method to quantify the nodes of human error. Operators must keep in mind: "Do not put your hands in the mold area, keep your eyes on the workpiece, and do not take chances" - any negligence of 0.1 seconds may cause irreversible damage.   If you have more ideas, please contact us!
