Description

technical field [0001] The invention relates to a high-precision sphere processing equipment. 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 it is widely used in ball bearings and is a key part of ball bearings. The accuracy of the bearing ball (spherical deviation, ball diameter variation and surface roughness) directly affects the technical indicators such as the motion accuracy, noise and life of the ball bearing, and then affects the performance of equipment and instruments. Compared with the traditional bearing steel ball material (GCr15), advanced ceramic materials such as silicon nitride have wear resistance, high temperature resistance, corrosion resistance, non-magnetism, low density (about 40% of bearing steel), and s...
