Abstract

The invention relates to a ceramic ball lapping method based on a combined-type fixation abrasive material grinding disc. The method comprises the following steps of: 1): a manufacturing procedure of the combined-type fixation abrasive material grinding disc: (1.1) selecting a cast iron grinding disc as a basic structure, and processing an annular groove on the cast iron grinding disc; (1.2) preparing ingredients of a fixation grinding apparatus; (1.3) manufacturing a combined-type fixation grinding disc; (1.4) forming a V-shaped groove on the upper end of the combined-type fixation abrasive material grinding disc according to the diameter of a ceramic ball to be processed, wherein the V-shaped groove takes the annular groove filled with a fixation abrasive material as a centre; and (2) arranging the combined-type fixation abrasive material grinding disc on a lower plate of a lapping machine, wherein an upper plate adopts the cast iron grinding disc or the combined-type fixation abrasive material grinding disc; placing the ceramic ball to be processed in a raceway of the lower plate; and starting the lapping machine so as to realize finish machining on the ceramic ball. The lapping method provided by the invention has the advantages of improving the utilization ratio of the fixation abrasive material, reducing the difficulty in forming a processing groove on the grinding disc and finishing, reducing the production cost, reducing the processing non-cutting time, and improving the processing efficiency.

Description

technical field

[0001] The invention relates to the technical field of ceramic ball grinding, in particular to a grinding method for ceramic balls. Background technique

[0002] With the development of industrial technology, performance requirements such as high speed, high precision and high reliability have been put forward for machine tools and instruments. Compared with traditional bearing steel, alumina ceramics have low density, high hardness, high elastic modulus (high stiffness), wear resistance, low thermal expansion coefficient, good thermal and chemical stability, insulation, and non-magnetic properties. The comprehensive performance is considered to be the best material for manufacturing bearing rolling elements, and it has achieved great success in the application of ceramic ball bearings (steel bearing rings, ceramic material rolling elements.). Ceramic ball bearings have long service life (2 to 5 times that of steel bearings), high speed, good overall precisi...
