Staggered roller-type super-precise polishing device of precise ball and processing method of same

Abstract

The invention discloses a staggered roller-type super-precise polishing device of a precise ball and a processing method of the same, wherein the precise ball is placed between an upper layer and a lower layer of polishing rollers which are staggered, the polishing rollers are coated with soft polishing cushion covers, and rotation speeds of the upper layer and the lower layer of polishing rollers are combined and changed according to a function relationship as controlled by a control device, so that a rotation direction of the precise ball sandwiched by the upper and lower layers of polishing rollers can be changed continuously. In addition, loads are added and a polishing liquid is sprayed in order to realize uniform polishing of the surface of the precise ball sandwiched by the upper and lower layers of polishing rollers. The staggered roller-type super-precise polishing device of the precise ball and the processing method of the same provided by the invention have a simple and compact structure, low production cost and easily-realized functions, can conveniently realize precise polishing processing to the precise ball by the soft polishing cushion sleeves and can realize the uniform and whole-enveloped polishing of the precise ball in order to obtain a super-precise ball with high superficial quality and no damage.

Description

technical field [0001] The invention relates to the technical field of precision ball polishing, in particular to an interlaced roller ultra-precision polishing device for precision balls and a processing method thereof. Background technique [0002] As an important component in bearings, roundness meters, gyroscopes and precision measurement, precision balls are in huge demand and are widely used in precision machinery, aerospace, military defense, petrochemical and other fields. Precision balls have extremely high processing requirements for their shape accuracy and surface quality. [0003] As the final processing process of precision balls, polishing is mainly to reduce the surface roughness of the ball, remove surface pitting, scratches and other defects, reduce or eliminate sub-surface damage, and maintain or further improve the sphericity. [0004] At present, the processing methods of precision balls mainly include V-shaped groove ball processing method, active cont...
