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