Laser cutting machine laser drilling auxiliary process to improve the accuracy of laser drilling, sometimes need to adopt some auxiliary process procedure and process measures, including the following: (five o 'clock
A)
A positive pressure on the surface of workpiece, or with a low pressure on the opposite side of the workpiece, can help remove vaporized material during the process of punching and increase the discharge of liquid phase.
(
2)
Safe place under the workpiece loading a photoelectric detector, can timely detect the workpiece through or not.
(
3)
Using liquid membrane or metal platinum covers artifacts, can make the taper hole is reduced, and prevent the liquid splashes.
(
4)
In order to prevent melt accumulated in the hole, can put the vaporization temperature below the melting temperature of the material processed materials on the back of the processed workpiece.
(
5)
Using laser as a machining tools on the workpiece pores, then use other methods to achieve the required accuracy.
At present commonly used with carborundum mechanical processing, with the punch aperture finish machining, metal wire, chemical etching method and so on.
