AN METHOD FOR CUTTING FORM OF CHIP BREAKER ON PCD/PCBN USING LASER AND AN INSERT FOR CUTTING HEAD

摘要

The present invention is a method for processing a chip breaker shape on the upper surface of the PCD / PCB using a laser, the pulse repetition frequency of 100 ~ 300 Hz, the pulse width of 0.05 ~ 0.15 mS, the energy per pulse of 0.1 ~ 0.3 J, 50 ~ It is characterized by processing the chip breaker shape at a feed rate of 70 mm / min, the amount of cutting movement of 0.01 ~ 0.2 mm.;According to the present invention as described above, by cutting the chip generated by processing the chip breaker shape on the PCD or PCBN by precisely controlling the processing conditions of the laser there is an effect that can be prevented in advance any problems caused by chip generation. .;Cutting, Machining, Inserts, Chip Breakers, Holders, PCD, PCBN.
