Usage:

Our products are being widely exported to Europe, the USA, Japan, South Korea, Middle Asia, and Southeast Asia.

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.
