Laser cutting machine sheet metal processing techniques

The technique of laser cutting machine sheet metal processing: 1, laser quenching. Also called laser phase transformation hardening, is to use after focusing laser beam to the surface of steel material, make its temperature rise rapidly to the phase transition point above, when after you remove laser processing, as a result of rapid heat conduction of is still in the low temperature of lining material, make the surface under the fast cooling to the martensite phase transformation point, hardening layer. With heating speed, quenching hardness, quenching position control, without the advantages of quenching medium. 2, laser cutting engraving. Laser seals machine, high pressure boiler tube, stranded tungsten wire, electric car accessories, high pressure boiler pipe, seamless tube, powder metallurgy, shuangli fused technology, laser processing surface is to use laser beam above the substrate surface heated to melting temperature, when the laser beam due to base material after you remove the internal cooling of thermal conductivity and make the melting layer surface fast cooling and surface treatment technology of solidification. Particularly suitable for gray cast iron and nodular cast iron surface strengthening, can improve the wear resistance. 3 welding, laser cutting. Compared with other welding methods, do not need the electrodes and the fill material, can be localized heating, ensure rapid heating. Has nothing to do because of no mechanical contact, when welding the ruled out the possibility of material to be welded parts, welding area is almost not affected by pollution. Can the high melting point, refractory metal, or different thickness, different metal materials for welding. And bit for example using laser welding diamond saw blades, can lift the combination of matrix and diamond bit as intensity, and high geometric accuracy, can be suitable for dry cutting, overcome the phenomenon of cutter tooth loss.
