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.And 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.
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:

Moresuperhard recommends ceramic bond diamond grinding wheels for the rough grinding of the cylindrical surface of the diamond layer on PDC cutters. These wheels demonstrate excellent efficiency and cost-effectiveness compared to traditional resin bond wheels.
PCD tools offer excellent hardness and wear resistance for machining difficult materials, but grinding them poses unique challenges. This article explores common issues such as chipping, high surface roughness, dimensional deviations, burning, and grinding wheel wear. Learn practical solutions to optimize grinding parameters, wheel selection, and machine accuracy to improve tool life and reduce costs.
