Ball bearing is produced by special steel ball mill, mainly through the following process:
1, production of embryos: use a variety of techniques to produce a variety of globular rough.
2, grinding: match the rough into the rough dimensions of spherical, upper and lower two concentric circular, section with multiple dimensions are the same as a triangle grooved disc grinding, adding oil, coarse Abrasives; disc under disc rotation, fixed on. More than grinding the coarse grinding machine. Depending on your needs, coarse grinding can have multiple road.
3, cleaning: every time you complete a coarse grinding, is to stick to the surface of oil and coarse abrasive residual wash.
4, fine grinding: the rough input completed rough grinding fine grinding machines; join the low-viscosity oils and fine abrasives, grinding to a standard size.
5, polished: the process is similar to coarse grinding, fine grinding.
And then the heat treatment, some blast processing, some are not. Last operation is Polish, the General is a combination of Yan grinding and polishing liquid, so that the bearing steel ball manufacture.
