Fourth, the use of precision ceramic blades 1. Blade shape and specification selection (1) the greater the blade tip angle, the higher the blade tip strength, in order to strengthen the blade tip strength, in the use should try to use the blade sharp angle blade . (2) For ceramic inserts with chipbreakers, the front angle should not be too large. The larger the rake angle of the insert, the lower the strength of the cutting edge, and it is easy to collapse during the cutting process. (3) The ceramic blade has high compressive strength. The tool structure with flat blade and negative rake angle can exert this advantage, avoiding bending stress and improving the impact resistance of the tool.
