ontheir products. However, differences in composition, heat treatment and other variables occur and these can affect service performance. Ball users can improve ball performance and cost by monitoring ball quality and service performance on a regular basis. This grinding ball quality control programme includes inspection.
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.

in still air or furnace. The heat treatment cycle shall be established by means of process qualification to meet the requirement of the hardness and microstructure. VI. Finish: All casting shall be properly fettled, tumbled and dressed. All surfaces shall be thoroughly cleaned. VII. Freedom From defects: All the balls must be free.
The ball production process is divided in five different steps: heading, flashing, heat treatment, grinding and lapping. After an inspection check upon reception to check its suitability, the raw material certified by the supplier is worked on high-speed casting machines. The second step of the production process involves rolling.
