The Production

The ball production process is divided in five different steps: heading, flashing, heat treatment, grinding and lapping.

Heading

After an inspection check upon reception to check its suitability, the raw material certified by the supplier is worked on high-speed casting machines.

Flashing

The second step of the production process involves rolling the pieces between discs with concentric grooves to eliminate signs of casting and to increase the precision of the ball.

Heat treatment

Heat treatment, where necessary, gives the balls the maximum possible hardness and the best technical characteristics that can be achieved with the materials used.

Grinding

Successively several careful grinding processes using ceramic grinding wheels give greater dimensional precision and prepare the balls the next, final lapping process.

Lapping

This procedure gives the ball a perfectly shiny, compact and defect-free surface, with very low surface roughness, much lower than that required under ISO 3290.
