Grinding consists of a series of precision mechanical operations performed on mechanical parts and components in order to bring each individual detail within the usually extremely stringent hundredths/ thousandths tolerance required by the project. Mechanical grinding, both traditional and CNC, centre, centreless, internal and flat. In applications such as hydraulics, the hundredths and/or thousandths tolerances must necessarily be adhered to, in order to ensure tightness and fluid flow at very high pressure.

Roughness: on lathes we reach Ra 0.8, while on grinders we start at Ra 0.8 and progressively reduce to far lower figures.
