Abstract

The invention discloses a diamond grinding wheel with high wear resistance and long service life and a preparation method. The diamond grinding wheel manufactured through the method comprises a grinding wheel base body and a grinding material layer. The grinding wheel base body is made of steel, aluminum and other materials, and the grinding material layer is made of diamond which is of a hexahedron lattice structure and has the particle size of 150-500 microns. The prepared finished grinding wheel is high in mechanical strength, good in wear resistance and long in service life, can realize high-quality grinding machining of materials with high hardness, high viscosity and other attributes, and has a very good application prospect in the fields of casting grinding, cutting and the like.

Description

technical field [0001] The invention relates to the field of preparation of abrasive materials and abrasive tools, in particular to a diamond grinding wheel with high wear resistance and long service life and a preparation method thereof. Background technique [0002] With the vigorous development of aerospace, rail transit, automobiles and ships, and high-end clocks and watches, the hardness and brittleness of materials used in key components have also gradually increased, resulting in a sharp increase in the difficulty of grinding. For the processing and manufacturing of such parts, the grinding method was generally used in the early days, that is, grinding with grinding powder; the disadvantage is that a large amount of dust and sewage will be generated during the grinding process, which will cause serious pollution to the environment, and the consumption of grinding powder is large, Low utilization. [0003] With the advancement of grinding technology, the method of usi...
