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

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

Is a clean process in Hard Turning tool with basic without using cutting fluid, thus saving the associated cutting fluid transport means and processing means, saving investment costs; cutting fluids typically 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.
