How to choose the Pcd cutting tool materials?
(1) reasonable choice between PCD granularityPCD granularity choice related to cutting tool processing conditions, such as the design used in the finishing or superfinishing knives, should choose high strength, good toughness, good shock resistance, fine grain of PCD.Coarse grain of the PCD cutting tool can be used for general rough machining.The granularity of PCD material for tool wear and damage performance significantly.Research shows that: the greater the PCD grain sizes, the stronger the cutting tool wear resistance.By De Beers, 002 and 025 two SYNDITE SYNDITE PCD cutting tool machining SiC base composite material of tool wear test results show that the grain size of 2 microns SYNDITE 002 PCD material is easy to wear.(2) the reasonable choice between PCD blade thicknessUnder normal circumstances, the PCD compact layer thickness is about 0.3 ~ 1.0 mm, with carbide layer after the total thickness of about 2 ~ 8 mm.Thinner PCD is advantageous to the blade with a thick layer of edm.De Beers company came out with the 0.3 mm thick of PCD compact can reduce grinding force, improve the edm cutting speed.PCD compact and blade material, when welding the hard alloy layer thickness cannot be too small, in order to avoid the difference between the two materials in combination with surface stress caused by the stratification.
