Problems solved by technology

The rubber sheet grinding wheel itself has less loss, but the cutting efficiency is low, and the cutting heat generated is indeed high, leaving ablation marks and burrs on the incision section of the workpiece, and also causing the resin bond of the sheet grinding wheel to be carbonized, which makes the sheet grinding wheel prone to Brittle crack damage, short service life, and the hardness and self-sharpening are not ideal

Abstract

The invention provides a slice resin grinding wheel and a preparation method thereof and belongs to the field of grinding tools. The slice resin grinding wheel solves the problems that existing slice resin grinding wheels are easily subjected to brittle fracture and damage and are short in service lives and not ideal enough in rigidity and self-sharpening performance. The slice resin grinding wheel comprises a grinding body and a reinforcing piece placed in the grinding body so as to enhance rotation strength of the grinding body. The grinding body comprises, by weight, 30-40 parts of white fused alumina, 65-75 parts of microcrystal fused alumina, 5-20 parts of green silicon carbide, 5-10 parts of resorcin-formalin, 10-20 parts of phenolic resin powder, 8-15 parts of cryolite powder and 10-20 parts of pyrite powder. The invention further provides the preparation method of the slice resin grinding wheel. The slice resin grinding wheel has the advantages of being low in production cost, high in rigidity, good in self-sharpening performance and long in service life.

Description

technical field [0001] The invention relates to a sheet resin grinding wheel and a preparation method thereof, belonging to the field of abrasive tools. Background technique [0002] Many workpieces often need to be ground and trimmed with grinding wheels after the processes such as casting, welding, processing and maintenance are completed. Grinding wheels are porous objects composed of abrasives and bonds. Abrasives, bonds and pores are the three basic components of grinding wheels. Due to the hardness of the abrasives, the bonding layer between the abrasives is very thin, resulting in almost rigid contact between the abrasives, so the grinding wheel has high rigidity, grinding ability and grinding efficiency, but this grinding wheel makes the grinding of the workpiece The surface is prone to scratches, and it is difficult to obtain better surface processing quality. With the different abrasives, bonding agents and grinding wheel manufacturing processes, the characteris...
