激光加工是用光作热源的热加工。我们所说的激光加工,主要是指利用激光进行钻孔、切割、焊接、热处理、划线、去重等这一些加工。对于激光加工说来,钻孔、切割、焊接,的原理都一样。都是用光学系统把激光束聚焦成一个直径仅有几微米到几十微米的光 Laser processing is the use of light as a heat source of thermal processing. We say laser processing, mainly refers to the use of laser drilling, cutting, welding, heat treatment, scribing, to some of these heavy processing. For laser processing, drilling, cutting, welding, the principle is the same. Are the optical system to focus the laser beam into a diameter of only a few microns to tens of microns of light
