Do you know how a ball is made?

Published:2012-08-05
  1. Heading: In the first step, heading machines cut wire into short lengths and form it into spherical shapes between dies.
  2. Deflashing: The flash line, a ridge left by the forming dies, is removed as balls roll between heavy, cast iron plates.
  3. Soft Grinding: Similar to deflashing, except that a grinding stone is used to improve precision.
  4. Heat-treating: Carbon steel balls are next carburized and hardened. Heat treatment imparts the desired hardness and case depth.
  5. Descaling: This step removes the residues and by-products from the heat-treating process.
  6. Hard Grinding: Slow, meticulous grinding assures proper sizing and sphericity, with tolerances as close as ±.0001".
  7. Lapping: Several proprietary lapping processes can bring balls to the requirements of ISO 3290 Grade 10 - 48.
  8. Finishing: Proprietary chemical and mechanical processes give the balls their final micro-smoothed finish, for increased wear resistance and product longevity.
  9. Inspection: All products pass through at least two 100% inspection stages, using proprietary, automated inspection processes.
