Production Line :

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

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 longevity.
