For solving the automatic chip wraping problem, there have the high requirements for the PCBN PCD cutting tools and the superhard tools with chip breaker is necessary.

Problems caused by Automatic Chip Wrapping            

1) Scratch on workpiece surface;

2) Chip winding on workpiece surface;           

3) The tool life is not stable;

4) The secondary positioning is not accurate due to chip wrapping;       

5) Chip conveyor can't discharge chip normally;          

6) The manipulator cannot work normally;            

7) The automatic detection system does not work.          

CBN PCD Tool Requirements for Automatic Machining            

1) Improve chip breaking requirements;

2) improve processing efficiency;            

3) Increase tool life and reduce tool change frequency;
