Precision hard turning is a form of machining, a material removal process, which is used to create rotational parts by cutting away unwanted material. The turning process requires a turning machine, work piece and cutting tool. Hard Machining Process for improved metal removal rates in turning operation. It is concerned with designing machines, fixtures, and other structures that have exceptionally high tolerances, are repeatable, and are stable over time. The component we manufacture as a geometrical tolerances such as roundness, parallelism and flatness of above 5 micron and surface finish within 5 micron and surface finish at 0.2 Ra.
