Manufacturer, operator of the superhard tools using hard turning effect do not know enough, generally considered only grinding hard materials;

That the tools cost too much. Hard turning initial tooling costs higher than normal carbide tools (such as pcbn ten times more expensive than ordinary carbide), but its share in the cost per part is lower than the ground, and the benefits than the average carbide is much better;

Mechanism of super hard tool is not enough;

Specification super hard tool is not sufficient to guide the production practice.

Therefore, in addition to the mechanism of super hard tool depth study, but also the need to strengthen the training super hard tool of knowledge, experience demonstrates the success and strict practices to make this efficient, clean production and processing methods applied to more practical.
