Embodiment Construction

[0027] The present invention will be further described below.

[0028] A high-efficiency grinding / polishing process for high-precision ceramic balls. The process includes the following processes: rough grinding, semi-finishing, finishing, super-finishing, and polishing, specifically:

[0029] (1), coarse grinding

[0030] The processing conditions are as follows: equipment: double-disc self-rotating eccentric V-groove grinding machine. Grinding Disc: Fixed abrasive grinding disc. Abrasive: diamond; abrasive particle size: W25; mass percentage of abrasive in the grinding disc is 20% to 80%, for example, 50% is used, and the rest is binder; load pressure: 10 (N / ball). Speed ​​combination: Ω C : 70(rpm);Ω B :Ω B =Ωc. Grinding liquid: water.

[0031] (2), semi-finishing

[0032] The processing conditions are as follows: equipment: double-disc self-rotating eccentric V-groove grinding machine. Grinding Disc: Fixed abrasive grinding disc. Abrasive: diamond; abrasive partic...

Abstract

The invention relates to an efficient grinding/polishing process of high-precision ceramic balls, which comprises the following steps: (1) rough grinding; (2) semi-finish grinding; (3) finish grinding; (4) super-finish grinding; and (5) polishing, wherein a double-disc self-rotating eccentric V-shaped slot grinding machine is adopted in the steps (1)-(2), and a grinding machine with double self-rotating grinding discs is adopted in the steps (3)-(5). In the invention, not only can higher processing accuracy and processing efficiency be realized, but also processing equipment has simple structure, and the manufacturing cost is lower.

Description

technical field [0001] The invention relates to a grinding process for spherical parts, in particular to a precision grinding / polishing process for high-precision ceramic balls in high-speed, high-precision ceramic ball bearings, and belongs to the processing technology for high-precision spherical parts. 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), advanced ce...
