Abstract

The invention relates to a resin grinding plate for ultraprecise processing of bearing balls, which is mainly prepared by carrying out pressure molding and high-temperature curing on a grinding material composed of white alundum and green silicon carbide, and resin composed of phenolic resin and polyamide resin. The volume density s 2.8-3.2 g / cm<3>, the hardness is HRC 50-65, and the uniformity of hardness is HRC + / -3; and the product has flat surface and does not deform. The resin grinding plate is used for an ultraprecise grinding process of precise bearing balls. The resin grinding plate provided by the invention has the advantages of high density, high hardness and favorable toughness, and enhances the production efficiency by 100% as compared with the cast iron plate plus chromium oxide in the traditional technique. The processing precision of the product is high; the dimensional tolerance is lowered by 20% as compared with the Chinese Standard, and the geometric tolerance is lowered by 10%; and no pollution is generated in the working process.

Description

technical field [0001] The invention relates to an abrasive material, namely an ultra-precision machining resin abrasive plate for bearing balls and a manufacturing method thereof. Background technique [0002] Bearings are the key components of machinery, and bearing processing represents the level of mechanical processing in a country. In recent years, with the rapid development of aerospace, high-speed rail, wind power, and nuclear power, the technical level of high-precision bearings has become higher and higher. Bearing balls are the key parts of bearings, therefore, the development of high-speed, high-precision grinding of bearing balls is a crucial high-end technology. The bearing ball processing equipment is mainly based on the precision grinding plates used for fine grinding and super fine grinding. [0003] Bearing ball ultra-precision machining resin grinding plate is mainly used for processing high-precision bearing steel balls and bearing ceramic balls. The gr...
