Production process:  

 Heading: In the first step, heading machines cut wire into short lengths and form it into spherical shapes 

 Deflashing: The flash line, a ridge left by the forming dies, is removed as balls roll between heavy,

 cast iron plates.

Soft Grinding: Similar to deflashing, except that a grinding stone is used to improve precision.

 Heat-treating: Carbon steel balls are next carburized and hardened. Heat treatment imparts the

 desired hardness and case depth.

 Descaling: This step removes the residues and by-products from the heat-treating process.

 Hard Grinding: Slow, meticulous grinding assures proper sizing and sphericity, with tolerances

 as closeas ±.0001".

Lapping: Several proprietary lapping processes can bring balls to the requirements of ISO 3290

Grade10 - 48. 

Finishing: Proprietary chemical and mechanical processes give the balls their final micro-smoothed finish,

for increased wear resistance and product longevit
