Shaft and bearing the processing characteristics

1 shaft machining characteristics

Shaft is generally cylindrical, surface roughness requirements are relatively high, so the surface must be grinding shaft, grinding the workpiece (shaft) Shaft rotation direction should be the direction of rotation when the actual work is consistent. If the shaft surface roughness after grinding also meet the requirements, need for grinding or polishing. Shaft material after heat treatment should be sufficient hardness for grinding and polishing.

(2) processing characteristics bush holes

Roller bearing materials are usually softer inner cylindrical surface should not be processed by grinding method can be used boring, boring diamond, scraping or grinding process.
Grinding should not be used with the shaft with research methods, and should use a special, dimensions and bearing the same hole size pestle.

Scrapers used for part of the bush bearing, with a wide blade scraper machine scraping. When hand-scraped, scratched should be shallow.

Inner surface of the complex shape of the bush, should be based on the specific shape using a special method of boring.
