Laser cutting machine cutting process
Nov 25, 2016

Laser cutting machine in the process of cutting, beams focused by a lens of the cutting head into a very small focus, focus high power density, including cutting head is fixed on the z axis. At this time, the beam input far more than are materials reflecting, parts of conduction and diffusion of heat, quickly heated to melting and vaporization temperature of materials at the same time, a high-speed airstream from the coaxial or non-concentric side will melt and vaporize the material, out cutting hole is formed. With the focus and the relative motion of the material, the width of the hole forming a continuous narrow kerf, material cutting.

At present, the laser cutting machine is used in the outer optical part flying optical system. Emitted from the laser beam reflector 1, 2, 3 to the cutting head on the focusing lens, focusing on the material surface form the spot. Reflective lenses 1 fixed to the fuselage still; beam reflectors x 2 along with the beam movement to movement; reflectors on the z axis 3 and y to the z shaft movement movement. It is easy to see from the diagram, in the process of cutting, as the beam x movement, part of y to the z axis movement, the length of the light path is changing.
