Abstract

The invention discloses a ceramic bond diamond grinding wheel, wherein the matrix is an aluminum matrix, the abrasive layer is an annular working layer, which is formed by thirty to fifty ceramic bonding agent diamond blocks obliquely embedded on the end surface of the matrix. The angle between the line, which is the top end of the ceramic bond diamond block and the center of rotation, and the side of the ceramic bond diamond block is 30-35 degrees. According to the ceramic bond diamond grinding wheel, advantages are as follows: the manufacturing cost is reduced by using one or more of a largenumber of auxiliary abrasive, such as silicon carbide, boron carbide, aluminum oxide, and brown fused alumina to replace the expensive synthetic diamond; the heat transfer and heat dissipation effectof the ceramic bond wheel body, and the chip removal effect during the grinding by the grinding wheel are greatly improved, by bonding the ceramic bond diamond blocks; so that the invention has the characteristics of good cooling effect, good chip removal effect, no blockage, continuous sharpness, and high self-sharpening.

Description

technical field [0001] The invention relates to the technical field of grinding wheel preparation, in particular to a diamond grinding wheel. Background technique [0002] For the grinding of stainless steel parts, due to the high toughness of stainless steel, small thermal conductivity, and small elastic modulus, the grinding wheel often sticks and clogs during the grinding process, and a large amount of cutting heat is generated, resulting in burns on the machined surface, resulting in work hardening and deformation of the workpiece. As the quality of today's products is getting higher and higher, it is difficult for traditional grinding wheels for grinding stainless steel to grind high-quality stainless steel parts with high efficiency. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the purpose of the present invention is to provide a kind of diamond grinding wheel for stainless steel, improve from the structure of grinding ...
