Abstract

Disclosed are a diamond resin grinding plate and a manufacturing method thereof. The diamond resin grinding plate comprises a base material and a diamond grinding body, the base material is a superfine micro-powder resin cementing material, the base material and the diamond grinding body are ring belts with the same circle center and are bonded together at an interval, superfine micro-powder is distributed on the ring belt for grinding the same, diamond materials are distributed on the ring belt for grinding the same, and the diamond resin grinding plate is formed through compression molding and high-temperature hardening, so that the diamond resin grinding plate is smooth in surface and free of deformation and is used for superfine grinding processes of precision bearing balls. The superfine micro-powder in the superfine micro-powder resin cementing material is one or two of superfine white corundum micro-powder and superfine green silicon carbide micro-powder, and a resin cementing material is one or two of phenolic resin and polyimide resin. The advantages of the diamond resin grinding plate are obvious, and the base material is the superfine micro-powder resin cementing material, so that the diamond resin grinding plate has two functions as a superfine micro-powder resin grinding plate and a diamond micro-powder resin grinding plate, cost is greatly saved for manufacturers, and consumption of diamond microparticles is reduced.

Description

technical field [0001] The invention relates to a grinding material, namely a diamond resin grinding plate and a manufacturing method thereof. Background technique [0002] Bearings are key components of machinery, and bearing processing represents the level of a country's machining. 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. Bearing ball processing equipment is mainly precision grinding plates used for lapping and super-finishing. The grinding plate of the bearing is an annular circular plate, and the working surface of the circular plate is arranged with an annular groove, and the bearing steel ball is placed in the groove, and the bearing steel ball is polished by the rotati...
