Superfinishing

What is the Superfinish?

It is a physical/chemical process to optimize the surface finish of a part, decreasing the roughness values (Ra and Rz).
It does not remove material, the dimensions of the part are not altered.
Isotropic: it works in all directions, contrary to traditional machining techniques.

What are the advantages?

Reduces friction between two metals in contact
Reduces temperature due to less friction
Reduces material fatigue
Removes fragmented metal particles in the machining and case hardening processes of the workpiece
Power increase
Extends component life

Before and after application of superfinish treatment

Which parts can be treated?

Principalmente se aplica en cajas de cambio, árboles de levas y todo tipo de piñones, así como todo tipo de piezas metálicas que esten mutuamente en contacto unas con otras y en constante movimiento, generando roce permanente entre ellas.

How is it done ?

It is a process that lasts 8 hours, in which the pieces that we want to treat are put in a vibration equipment together with a special non-abrasive ceramic material and different chemical products.
