A study of NC limit traction technology in the scope of cutting hard materials

In this paper, we discussed the usage of limit traction technology within the traditional inner circle-cutting machine with computer numerical control to achieve a flexible, fast cutting and rapid withdrawal knife function. Such a system will improve the production efficiency and reduce the edge collapse and corner collapse defects. Control circuit in the system is simple, scalable, and can be widely used in a variety fields of hard materials cutting and processing.
