2) Cold Rolling Forming

Cold rolling process is a can improve material utilization, improve the metal tissue density, linear flow to keep the metal advanced process method, which is a non-chip processing methods. Theoretically, cold rolling forming products were not subject to direct heat treatment and turning grinding. Currently, the cold rolling process is mainly used in small deep groove ball bearings, the main process is:
Rough forging (ring) - Turning (except Channel) - Rolling (groove and chamfer) the entire path - Polishing end faces
Using cold Backing bearings process and forging molding process, the accuracy of the product in addition to precision equipment affected by the outside, but also by mold accuracy.
3) Turning Molding
In the bearing industry, the traditional molding techniques is the use of dedicated turning lathe, a centralized method to complete forming process. However, this method is difficult to adjust the equipment used, low precision machine tools, material utilization is low, so the process method is being phased out.
With the development of science and technology, the rapid development of CNC turning machines and increasingly sophisticated. Currently, a number of complex shape, high precision products are increasingly using CNC turning molding technology.
In summary, the ferrule molding should be directed toward the metal material utilization, high efficiency, high precision molding direction. Therefore, high-speed upsetting technology, cold rolling technology, CNC turning molding technology will be more and more applications.
