Abstract
0Cr17Ni4Cu4Nb stainless steel has problems such as severe work hardening, serious tool wear and difficulty in heat dissipation in the deep hole processing. Thus the super-long deep hole drilling of 0Cr17Ni4Cu4Nb stainless steel was studied. The material and geometric parameters of drilling bit were selected reasonably. The super-long deep hole drilling test of 0Cr17Ni4Cu4Nb material was designed and carried out. The drilling process and reason for the axis deviation were investigated. The experimental results show that reasonable parameters of drilling bit and drilling process can better control the hole axis deviation. It provides technical parameters and experience for actual production.
