Surface finishing degree and dimensional accuracy are crucial in most applications and they depend on the production process which has been chosen. In the case of stock removal machining they mainly depend on the finishing process. The most widespread finishing process is grinding.. A modern grinding machine should be capable of achieving high surface roughness, tight tolerances and, last but not least, should have a complex structure but at the same time be easy to use. Stability and rigidity of a machine tool are given by its basement as well as by other structural components it consists of. Starting from an optimal design, these should be made employing good quality cast iron, cast following strict rules and undergoing proper thermal treatments. Gioria is certainly up to this, as well because it was born at the beginning of the sixties exactly as a cast iron foundry.
