1 Cold Rolling Forming:

      Cold rolling process is one that enhances material utilization, improving metal tissue density, to maintain the advanced technology of metal flow linear method, which is a non-chip processing method. In theory, cold rolling forming products for turning without heat treatment and grinding can be directly processed. At present, the cold rolling process is mainly used install, medium and deep groove ball bearings, the main process as follows:

  Forging blank (ring) - Turning (except Channel) - Rolling (groove and chamfer) the entire diameter - Polishing the surface at both ends

  By cold rolling process and forging forming process, the product of precision equipment, precision affected by the addition, but also by the mold accuracy.

(2) Forging forming

Metal forging process can be eliminated by the inherent defects, improve metal structure, a reasonable distribution of the metal flow lines, metal tightness is good. Forging molding process is widely used in bearing molding; you can complete from the small diameter of ~ 20mm diameter 5000mm products to the processing of large products. Forge common molding methods: hot forging process, cold process, warm forging process, forging our country to the main.

  Processing equipment because of its shape forging process is divided into different: free forging process, forging process presses, flat forging machine upsetting forging process and high-speed machine forging process.

    3 Turning forming

  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 are low, and so the process method is being phased out.

  With the scientific and technological development, CNC turning machines and the rapid development of increasingly sophisticated. Currently, a number of complex shape, high precision products are increasingly used CNC turning molding technology.
