Grinding abrasive wheel

Abstract

The invention discloses a grinding abrasive wheel. The grinding abrasive wheel is composed of an abrasive wheel body, a grinding layer at the outermost end and a through hole which is formed in the center of the abrasive wheel body, the grinding layer is composed of a plurality of grinding blocks arranged at intervals, each grinding block comprises the the following raw material components of, inparts by weight, 20-35 parts of titanium steel, 1-10 parts of zinc borate, 1-10 parts of dimethyl silicone oil, 5-15 parts of nano silicon nitride, 5-15 parts of polypropylene, 5-15 parts of a nano mesoporous molecular sieve, 1-10 parts of magnesium oxide, 5-10 parts of ferric pyrophosphate and 1-5 parts of cobalt, and a plurality of chip removal grooves are formed in the end faces of the grindingblocks. According to the grinding abrasive wheel, the grinding performance of the abrasive wheel is greatly improved, the hardness is high, the abrasion resistance and the buffering effect are good,the better cooling and chip removal effects are achieved, and the grinding quality of the abrasive wheel is further improved.

Description

technical field [0001] The invention relates to the technical field of grinding processing, in particular to a grinding wheel. Background technique [0002] As a grinding tool, the grinding wheel is playing an increasingly important role in the industrial field. When performing rough grinding, semi-finishing, fine grinding, grooving, cutting, etc. on the surface of metal or non-metallic workpieces. Due to the high-speed rotation, it needs to withstand a large impact force. When the grinding wheel cylindrical grinding meets the contact surface between the grinding wheel and the part, the part will have unevenness, and the parallelism, flatness, and roughness cannot meet the technical requirements: it is due to the large arc shape of the grinding wheel blade, the large frictional resistance, and the grinding area. The temperature is high, the parts are prone to thermal deformation due to high temperature, and the vertical pressure process is unstable, resulting in uneven pre...

Problems solved by technology

When the grinding wheel cylindrical grinding meets the contact surface between the grinding wheel and the part, the part will have unevenness, and the parallelism, flatness, and roughness cannot meet the technical requirements: it is due to the large arc shape of the grinding wheel blade, the large frictional resistance, and the grinding area. The temperature is high, the parts are prone to thermal deformation due to excessive temperature, and the vertical pressure process is unstable, resulting in uneven pressing density, heavy load on the substrate, and grinding wheel debris cannot be discharged in time, and the grinding wheel is prone to blockage, which directly affects the grinding process. cutting quality
