PCD Fiber Laser Cutting Machine

The principle of laser cutting PCD is that a laser beam with extremely high energy density irradiate the surface of polycrystalline diamond, and part of the light energy is absorbed by the surface and converted into heat energy. The local temperature of the irradiation spot rises rapidly to tens of thousands of degrees, which makes the polycrystalline diamond material melt or even vaporize locally and form pits.

The manufacturing process of PCD tool is described in the following figure:

Application of PCD fiber laser cutting machine:

PCD laser cutting machine is developed for super hard materials, mainly used for diamond, PCD composite sheet, PCBN, CBN, ceramics, CVD and other cutting and processing.

PCD laser cutting machine can process multi-blade grinding head, multi-blade milling cutter, drill bit, tooth cutter, special-shaped grinding head, PCD cutter, CBN cutter, PCBN cutter, etc. The finished products can be used in the processing of spherical cutter, ball milling cutter, forming cutter, chamfer cutter, round nose cutter, drill bit, tap and other super hard cutting tools.

Advantages of PCD fiber laser cutting machine:

1.High working efficiency and good quality.

2.The world's top imported fiber laser, stable performance.

3.Low cost, energy saving and environmental protection. No special consumables during cutting.

4.Easy operation. Optical fiber transmission, no need to adjust the optical path.

5.The movement is stable and the speed is fast. Because of optical fiber is the high efficiency, the stable and high-speed linear motor improves the processing quality of products.

6.Software and hardware cooperate to prevent damage of products and equipment caused by misoperation.

7.The accuracy is high. It can effectively reduce the errors caused by artificial feeding and mechanical positioning.
