Laser region manipulation rupture
In the laser area, a laser with high efficiency relative density of energy is used to carry out the scanner on the surface of ductile raw materials, so that the raw materials will emit a small groove when exposed to heat, then release a certain working pressure, the ductile raw materials will crack along the small groove. Q power switch laser generator C02 laser generator are commonly used in laser area. Manipulative fracture is caused by the steep temperature spread all over the groove when laser is used to carve groove, which causes part of welding stress in ductile raw material causes the raw material to break along the small groove.
Characteristics of fiber laser cutting
Compared with other thermal laser cutting methods, the general characteristics of fiber laser cutting are faster cutting speed higher quality. In fact, it can be summed up as follows.
High cost performance of laser cutting
Due to the small light spot, high specific energy faster laser cutting speed, fiber laser cutting can obtain good laser cutting quality.
① The results show that the incision is thin narrow, both sides of the slit are parallel vertical to the surface. The precision of laser cutting parts is ± 0.05mm.
② The surface of laser cutting is bright beautiful, the roughness is only tens of microns. Even fiber laser cutting can be used as the final process. The price of pipe cutting does need to be machined, the parts can be applied immediately.
③ After the raw materials have been cut by fiber laser, the total width of thermal hazard zone is large, the characteristics of raw materials around the slit are almost unaffected. Moreover, the deformation of the product workpiece is small, the laser cutting precision is high, the geometric shape of the slit is good, the cross-section of the slit shows a relatively standard square.
Fiber laser cutting, oxyacetylene laser cutting plasma cutting are adopted. The raw material of laser cutting is 6.3mm thick high carbon steel plate.
