The Manufacturing process for balls - Balls for Bearings

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.
