摘要

Abstract

During the gun drilling process of 34CrNiMo6 steel

the drilling temperature is high

the chip removal path is long

and the tool wear is severe. In response to the problems of poor surface quality and difficult control of processing quality in deep hole drilling of the difficult-to-machine material 34CrNiMo6 steel

an experimental study on the deep hole drilling of 34CrNiMo6 steel with machine-clamped gun drills was carried out. The influence mechanism of the spindle speed and feed rate of the machine tool on the processing quality was studied

and the torque and the axial force Fz in the Z direction were quantified by combining the DEFORM-3D simulation software

achieving the optimization of the drilling process. The experimental results show that when the spindle speed n = 1600 r/min and the feed rate f = 40 mm/min

the surface roughness and straightness of the deep hole are relatively good

the processing process is stable

and the chip removal effect is good.
