数控线切割机运丝机构的断轴问题长期影响机床稳定工作。我们从七七年开始对运丝机构的工作状态,传动轴的受力情况等方面作了分析,并作了相应的改进。运丝机构传动轴断裂的主要原因是疲劳破坏。疲劳破坏往往会在材料所承受的拉应力
CNC wire cutting machine thread cutting mechanism of long-term impact on the stability of the work machine. From the beginning of the seventies and seven seven, we made an analysis on the working status of the wire transport mechanism and the stress on the drive shaft, and made corresponding improvements. The main reason for breaking the shaft of the wire transmission mechanism is fatigue failure. Fatigue damage often leads to tensile stresses on the material
