With the rapid development and wide application of laser technology, fiber laser cutting machine has entered our life from the industrial field. In our applicable process, more and more different materials are cut. However, when using fiber laser cutting machine to cut different materials, the cutting method should also be adjusted appropriately. Now let's see with Xiaobian what are the different cutting methods of different metals?
1、 Stainless steel cutting
Generally, nitrogen is used to cut stainless steel metal plates to prevent oxidation and burr free edges. It can be welded directly without post-treatment. According to the characteristics of stainless steel materials, it can accelerate the fluidity of liquid and make the cutting efficiency higher and faster. The effect of cutting with oxygen may be worse than that with nitrogen, resulting in blackening and unsmooth end faces.
2、 Carbon steel cutting
Because carbon steel contains carbon, its light reflection is not strong, and its absorption beam is very good. Carbon steel is the most suitable for laser cutting machine processing among all metal materials, and its effect is the best. Therefore, carbon steel laser cutting machine has an unshakable position in carbon steel processing. The application of carbon steel is becoming more and more extensive. The maximum thickness of carbon steel plate can be cut by modern fiber laser cutting machine up to 20mm. The slit of carbon steel cut by oxidation melting cutting mechanism can be controlled within a satisfactory width range, and the slit of thin plate can be narrowed to about 0.1mm.
3、 Aluminum and alloy cutting
Aluminum cutting belongs to the melting laser cutting mechanism, and the auxiliary gas used is mainly used to blow away the molten products from the cutting area, which can usually obtain better cutting quality. For some aluminum alloys, attention should be paid to prevent the occurrence of intergranular microcracks on the slit surface.
4、 Copper and brass cutting
Like aluminum, copper and brass are high reflection materials, which need to be cut by laser cutting machine with "anti reflection device". Brass with thickness less than 1mm can be cut with nitrogen; Copper with thickness less than 2mm can be cut.
