Heat treatments and vibrofinishing
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.
