LaserCutterKnowledge

The role of laser cutting machine using auxiliary gas is mainly as follows: 1) Most of them use air, or oxygen, and nitrogen. The first purpose is to blow away the residual slag to achieve the best cutting effect. 2) While using the gas to chase away the metal slag, protect the lens and prevent the slag from sticking to the lens, affecting the cutting quality. 3) Using nitrogen cutting, it can effectively achieve the effect of smooth and clean cutting surface, no burr and no dross. 4) Using oxygen cutting, oxygen can support combustion and react with materials to increase cutting speed.

Laser quenching technology solves many problems that cannot be solved by conventional heat treatment processes. It has been widely used in metallurgy, automobiles, molds, hardware, light industry, machinery manufacturing and other industries. How much do you know about laser hardening? Laser quenching, also known as laser heat treatment, laser hardening, is the use of focused laser beams to rapidly heat the surface of metal materials to cause them to undergo phase transformation, forming a martensite hardened layer. Laser fusion hardening and laser impact hardening. Technical characteristics Laser quenched martensite grains are finer, dislocation density is higher, hardness is higher, and wear resistance is better. Minimal deformation, even no deformation, suitable for high-precision parts processing. In some cases, it can be used as the final processing procedure of materials and parts. Tempering is not required, compressive stress is obtained on the quenched surface, and c
