The main reasons for the chamfering of the high light machine are as follows:

1.High precision machine itself has better accuracy requirements;

2.High light machine should have good rigidity;

3.High light knife and feed speed;

4.Part structure and fixtures;

5. Excessive cutting heat and low cutting speed.

6. Cutting tools and cooling, cutting tool factors include cutting tool materials (common diamond cutting tools), cutting tool angle design, and tool holder dynamic balance. The cooling factors are: coolant, whether it has high-pressure cooling.
