Description

technical field [0001] The invention relates to a grinding device for spherical parts, in particular to a precision grinding / polishing device for high-precision ceramic balls in high-speed and high-precision ceramic ball bearings, and belongs to the technical field of high-precision spherical parts processing. 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 ball material (GCr15), advanc...
