Production Process:
1.Heading:
In the first step, heading machines cut wire into short lengths and form it into spherical shapes between dies.
2.Deflashing:
The flash line, a ridge left by the forming dies, is removed as balls roll between heavy,cast iron plates.
3.Soft Grinding:
Similar to deflashing, except that a grinding stone is used to improve precision.
4.Heat-treating:
Carbon steel balls are next carburized and hardened. Heat treatment imparts the desired hardness and case depth.
5.Descaling:
This step removes the residues and by-products from the heat-treating process.
6.Hard Grinding:
Slow, meticulous grinding assures proper sizing and sphericity, with tolerances as closeas ±.0001".
7.Lapping:
Several proprietary lapping processes can bring balls to the requirements of ISO 3290 Grade10 - 48.
8.Finishing:
Proprietary chemical and mechanical processes give the balls their final micro-smoothed finish, for increased wear resistance and product longevity.
