Precision Spheres | Production of precision ball bearings

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.
