1. High cutting precision: The laser cutting machine offers a positioning accuracy of 0.05 mm and a repeatability of 0.03 mm.
2. Narrow kerf: The laser beam is focused into a tiny spot, achieving high power density at the focal point; the material rapidly heats up to the point of vaporization, creating a hole. As the beam moves linearly relative to the material, these holes form a continuous, narrow kerf, typically 0.10–0.20 mm wide.
3. Smooth cut surfaces: The cut surfaces are free of burrs, with surface roughness generally controlled within Ra 6.5.
4. High cutting speed: Cutting speeds can reach 10 m/min, and maximum positioning speeds can reach 30 m/min-significantly faster than wire-cut EDM.
5. Excellent cutting quality: It is a non-contact process; the heat-affected zone at the cut edge is minimal, resulting in virtually no thermal deformation of the workpiece and avoiding the edge collapse often caused by mechanical shearing. Secondary processing of the cut edge is usually unnecessary.
6. No damage to the workpiece: The laser cutting head does not touch the material surface, ensuring the workpiece remains free of scratches.
7. Unaffected by workpiece shape: Laser processing offers great flexibility, allowing for the cutting of arbitrary shapes, including tubes and other irregular profiles.
8. Versatile material processing: Capable of cutting a wide range of materials, such as plastics, wood, PVC leather, textiles, and acrylic (Plexiglass).
9. Savings on tooling investment: Laser processing requires no molds, eliminating costs associated with mold wear, repair, and replacement time; this reduces processing fees and overall production costs, making it particularly suitable for large-scale products.
10. Material savings: Computer programming allows for the nesting of different product shapes, maximizing material utilization rates.
11. Faster sample turnaround: Laser processing can begin immediately after product drawings are finalized, enabling the rapid production of physical prototypes.
12. Safety and environmental friendliness: Laser processing generates minimal waste and low noise; it is a clean, safe, and pollution-free process that significantly improves the working environment.
