Description

technical field [0001] The invention belongs to the technical field of precision grinding, and in particular relates to a grinding wheel with controllable roughness and a grinding process. Background technique [0002] With the rapid iteration of the cutting tool industry, cemented carbide has become the main raw material for cutting tools due to its extremely high hardness, strength and wear resistance. Among them, solid carbide cutting tools are the mainstream at present. As raw materials for the early processing of cutting tools, the requirements for processing precision of cemented carbide rods are getting higher and higher, which are mainly reflected in high surface roughness, high brightness, and high shape. precision etc. [0003] In the grinding process to improve the precision of cemented carbide rods, the adjustment of surface roughness machining accuracy is generally achieved through matching grinding wheels and grinding processes. The common index requirements o...
