Problems solved by technology

[0004] Due to the special requirements of the bearing on the surface and the nature of the material itself, the selected abrasive must have high hardness and high control performance. In terms of controlling the size of the grinding workpiece, the traditional resin grinding wheel has excellent control performance, but the traditional The hardness of the resin grinding wheel is not enough, and the original resin grinding wheel has no precedent for bearing grinding

Abstract

The invention relates to a rubber grinding wheel special for bearings, and further provides a method for producing polishing wheel pieces. The rubber grinding wheel special for bearings comprises butadiene styrene rubber, sulfur, zinc oxide, resin powder, stearic acid, promoter M, pine tar, aluminum oxide and abrasive materials. The method for producing the polishing wheel pieces comprises the following steps of material weighing, material mixing, forming and vulcanization. The rubber grinding wheel made through the method is short in final temperature time because a thermal insulation time delay technology is adopted when the vulcanization point is reached, and accordingly the hardness of the grinding wheel is improved, the shape keeping performance of the grinding wheel is good, control over the size of a ground workpiece is greatly improved, and the application of the resin grinding wheel is extended; compared with the prior art, the rubber grinding wheel has the advantages of being durable and low in cost.

Description

technical field [0001] The invention relates to a special rubber grinding wheel for replacing imported bearings and a production method thereof, belonging to the field of mechanical accessories. Background technique [0002] Grinding wheel is the most important type of abrasive tool in grinding process. The grinding wheel is a porous body made by adding a binder to the abrasive, compacting, drying and firing. Due to different abrasives, bonding agents and manufacturing processes, the characteristics of grinding wheels vary greatly, which has an important impact on the processing quality, productivity and economy of grinding. The characteristics of the grinding wheel are mainly determined by factors such as abrasive, particle size, bond, hardness, structure, shape and size. [0003] Abrasives are the main raw material for making grinding wheels, which are responsible for cutting work. Therefore, the abrasive must be sharp and have high hardness, good heat resistance and ce...
