Grinding of a mechanical part is an operation intended to improve its surface state.

Grinding is performed on a machine tool designed especially for this purpose: the grinding machine. The aim is to rectify, or make a surface approach a perfect shape (in general: plane, cylinder or cone).

Grinding is often used to prepare friction surfaces, for example the seating of a shaft that rotates in a journal bearing or in a sealing ring. It can also be used to give the part a particular shape after the mould has been previously machined to the complementary shape. 

In the case of cylindrical grinding, the part rotates about itself in parallel with the axis of the grinder.

We have 4 centreless machines and 1 centred machine for external grinding of between Ø 3 and Ø 120mm.
