Properties of hardened layer of drilled deep holes
Original language description
Surface quality of deep hole after drilling may be evaluated by topography characteristics and surface layer characteristics. The article deals with hardness variation with distance beneath the surface of drilled deep holes. The bars of 32CrMoV10-12 steel with length of 500 mm were bored by the gun drilling system with different diameters of 6.5 mm and 8 mm. Microhardness of machined surface was measured by using microhardness tester LECO LM 247 AT and the Vickers indentor with a 50 g load and 10 s dwell time. The changes of microhardness and depth of hardened layer according to the hole length and diameters were discussed.
