If technical and design specifications so require, once the turning stages have been completed and before being ground, the parts can be sent for heat treatment or surface finishing by

• heat treatments (at our long-standing and extremely reliable partners), or
• vibrofinishing by tumbling (directly at our premises

Surface finishing by tumbling consists in the use of ceramic stones with a very fine mixture that are made to vibrate - inside special machines called tumblers - in contact with the surface of mechanical parts.

This is a far from aggressive, gentle friction; yet it is enough to bring the surface of hydraulic and mechanical components up to superfinish roughness levels, able to fully meet even the most stringent design specifications.
