Compared with grinding, hard turning state has the following characteristics:

High efficiency, good economic returns, the same volume of metal removed, the Hard Turning often use a larger cutting depth and higher speeds, while grinding is only a small depth of cut, or prone to grinding burn, Trail the component caused by large deformation, metal removal hard turning may be 3 to 4 times grinding, grinding energy consumption is only 1/5; turning in a single setup to complete multi-surface processing (such as cylindrical, bore, face, stairs, grooves, etc.), grinding can not; at the same processing efficiency, the investment is only grinder lathe 1/3 ~ 1/2, small footprint, low cost of auxiliary systems.

Is a clean process Hard turning tool with basic without using cutting fluids, thus saving the associated cutting fluid transport means and processing means, saving investment costs; cutting fluids generally contain toxic and hazardous substances, pollute the environment, it also undermines the health of the operator. Do not use cutting fluid Hard turning is a clean process.
