Abstract

The invention discloses a high-precise ball highly-efficient grinding and polishing processing method, in the processing devices for realizing the processing method, a V-shaped groove is formed by a pyramidal face abrasive surface of the outer of an inner plate of a lower grinding plate and a pyramidal face abrasive surface of the inside of an outer plate of the lower grinding plate, a loading pressure device acts on a ball billet through an upper grinding plate, three processing contact points of the grinding ball are formed by the V-shaped groove and the upper grinding plate, the upper grinding plate, the outer plate of the lower grinding plate and the inner plate of the lower grinding plate share a same rotary shaft; a rotating shafts of two plates among the upper grinding plate, the outer plate of the lower grinding plate and the inner plate of the lower grinding plate are driven by an electric motor; relative orientation changing is carried out on a ceramic ball through adjusting the velocity combination of the omega[B] and omega[C], so that the grinding trails are distributed on the face of the ball uniformly, thus grinding the surface of the ceramic ball uniformly. In the invention, the higher processing precision and processing efficiency can be realized, and the processing device has simple structure and low manufacturing cost.

Description

technical field [0001] The invention relates to a grinding / polishing processing method of a spherical part, in particular to a precision grinding / polishing processing method of a high-precision ceramic ball in a high-speed, high-precision ceramic ball bearing, and belongs to the processing technology of a high-precision spherical part. Background technique [0002] High-precision balls are important components in roundness meters, gyroscopes, bearings and precision measurement, and are often used as the benchmark for precision measurement, and play a very important role in precision equipment and precision machining. Especially in ball bearings, it is a key part of ball bearings. The accuracy of bearing balls (spherical deviation, ball diameter variation and surface roughness) directly affects the technical indicators of ball bearings such as motion accuracy, noise and life. Affect the performance of equipment and instruments. Compared with the traditional bearing steel bal...
