ISO 9001 & IATF16949 of our own factory named-Huatong
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.
