Abstract

The invention discloses a grinding wheel for machining a PCD blade. The grinding wheel comprises a grinding wheel base body, wherein a grinding layer is sequentially arranged on the grinding wheel base body, a wear-resistant layer is arranged on the grinding wheel base body, and the grinding layer comprises components, by weight, 40-45 parts of polycrystalline diamond powder, 7-11 parts of SiC whisker, 2-4 parts of hafnium boride, 3-6 parts of titanium boride, 0.5-1 parts of cobalt boride, 0.5-1 parts of tin oxide, 0.2-0.4 parts of iron oxide, 3-10 parts of pore-forming agent, 4-6 parts of resin. The grinding wheel has the advantages that while the same surface grinding quality is guaranteed, the higher feeding speed can be provided, machining efficiency is improved, when the finishing effect similar to that of an existing grinding wheel is achieved, consumption of a single grinding wheel is smaller than that of a grinding wheel in the prior art, the peripheral grinding wheel is sharper than the grinding wheel in the prior art, and the service life can be prolonged by about 40%.

Description

technical field [0001] The invention relates to the technical field of superhard tools, in particular to a grinding wheel for processing PCD blades. Background technique [0002] In recent years, the mechanical processing industry has developed in the direction of high speed, high efficiency and high precision. PCD cutters are made by welding PCD composite sheets to carbide or steel cutter bodies. PCD blades have high cutting efficiency and high precision of workpieces. It has high characteristics and shows excellent cutting performance in high-speed cutting of metal materials. It has been widely used in industrial fields such as automobiles, aviation, aerospace, and building materials. However, the high hardness and high wear resistance of PCBN inserts make it difficult to sharpen the tool, mainly reflected in the low material removal rate, large wear of the grinding wheel, low sharpening efficiency, and serrated cutting edge. The sharpening process of PCD tools has become...
