Polycrystalline Diamond Tool Blade Thickness

Under normal circumstances, the layer thickness of the PCD composite sheet is about 0.3 to 1.0 mm, and the total thickness after adding the cemented carbide layer is about 2 to 8 mm. The thinner PCD layer thickness is conducive to the EDM of the blade. The 0.3mm thick PCD composite sheet introduced by DeBeers can reduce the grinding force and increase the cutting speed of the electric spark. When the PCD composite sheet is welded to the cutter body material, the thickness of the cemented carbide layer should not be too small to avoid delamination caused by the difference in stress between the bonding surfaces of the two materials.
