Due to the transmission characteristics of the laser, the laser cutting machine is generally equipped with multiple CNC working tables, and the entire cutting process can be fully CNC controlled. During operation, the operator only needs to change the NC program, and the machine can cut parts of different shapes, which can perform two-dimensional cutting and three-dimensional cutting.
The laser with a power of 1200W cuts 2mm thick low-carbon steel plate, and the cutting speed can reach 600cm/min. Cutting 5mm thick polypropylene resin board, the cutting speed can reach 1200cm/min. The material does not need to be clamped and fixed during laser cutting.
The laser cutting incision is narrow and narrow, the two sides of the slit are parallel and perpendicular to the surface, and the dimensional accuracy of the cut parts can reach ±0.05mm.
The cutting surface is smooth and beautiful, and the surface roughness is only tens of microns. Laser cutting can be used as the last process, without mechanical processing, parts can be used directly.
After the material is laser cut, the width of the heat-affected zone is very small, the performance of the material near the slit is almost not affected, and the deformation of the workpiece is small, and the cutting accuracy is high. The geometry of the slit is good, and the cross-sectional shape of the slit presents a relatively regular rectangle.
During laser cutting, there is no direct contact between the cutting torch and the workpiece, and there is no tool wear. For processing parts of different shapes, there is no need to change the "tool", only the output parameters of the laser need to be changed. The laser cutting process has low noise, small vibration, and little pollution.
Compared with oxyacetylene cutting and plasma cutting, there are many types of laser cutting materials, including metal, non-metal, metal-based, and non-metal-based composite materials, leather, wood, and fiber.
