Study on Chip Morphology of Electric Hot Minipore Drilling

Abstract:

Based on the electric hot drilling and ordinary drilling to drill small hole for hard-to-cut materials stainless steel, the chip morphology and microstructure were studied, the cutting deformation coefficient of the ordinary drilling is bigger, and the chip is not easy to discharge from spiral groove, while the cutting deformation coefficient of electric hot drilling is small, the chips are discharged smoothly along the spiral groove, experimental results show that the electric heating drilling improves capacity of chip breaking, and reduces drill fracture result from the chip obstruction, so it improves the service life of the drill bit.
