刀台是立车刀架的末端环节 ,其性能好坏、刚度高低和自动化水平都直接影响着整机的性能、加工精度和生产率。因此 ,广泛开展转位刀台的研究 ,具有现实意义。电动转位刀台解决了以往转位刀台传动链长 ,占据机床内腔空间位置大 ,滑枕和刀台刚度低及夹紧力小等缺点 ,对机床的数控 The knife is the last link of the vertical turret, its performance is good or bad, stiffness level and automation level have a direct impact on the machine’s performance, machining accuracy and productivity. Therefore, it is of practical significance to carry out a wide range of research on indexable cutting tools. Electric rotary table knife to solve the previous indexing knife chain length, occupy the machine cavity space position, ram and knife stiffness and low clamping force shortcomings, the CNC machine tools
