Laser cutting machine is the processing of sheet metal parts to significantly improve the productivity of advanced equipment, with the processing of parts of high precision, short processing cycle, as well as processing without the traditional stamping die replacement can be processed any complex parts and other advantages, so more and more switchgear manufacturing enterprises to adopt.
Laser cutting is the use of focusing mirrors to focus the laser beam on the surface of the material to melt the material, while the compressed gas used for the laser beam coaxial blow away the melted material, and make the laser beam and the material along a certain track for relative movement, so as to form a certain shape of the cut. Laser cutting technology is developing rapidly and is increasingly being used as an advanced processing method, especially for cutting steel plates.
The obvious advantages of laser cutting technology over other methods are.
(1) good cutting quality narrow kerf width (generally 0.1-0.5mm), high precision (general hole centre distance error 0.1-0.4mm, contour size error 0.1-0.5mm), good surface roughness of the kerf (generally 12.5-25μm), the kerf generally does not require further processing can be welded.
(2) Fast cutting speed For example, using 2kW laser power, the cutting speed of 8mm thick carbon steel is 1.6m/min; 2mm thick stainless steel cutting speed is 3.5m/min, the heat-affected zone is small and the deformation is extremely small.
(3) Clean, safe, no pollution.
(4) from a technical and economic point of view is not suitable for the manufacture of metal sheet metal parts of the mould, especially the outline shape is complex, the batch is not large, the general thickness of less than 12mm mild steel, less than 6mm thick stainless steel, in order to save the cost of manufacturing moulds and cycle.
