线切割新工艺正在被广泛地采用,由于此机床尚未定型,各厂根据实际需要进行了不少的改进,正在日趋完善,但还存在着一些问题。例如,钼丝筒的联轴节的结构设计,至今还存在着不少问题,据我们了解,钼丝筒的电机主轴经常会断裂,虽然各厂采取了不少措施,改进装配工艺,加大电机的容量,即采用较大直径的主轴,均不能从根本上解决主轴断裂问题。
New technology of wire cutting is being widely used. Since this machine tool has not been finalized yet, various improvements have been made to the actual needs of the factories and are being perfected. However, there are still some problems. For example, the structural design of the coupling of the molybdenum wire tube has so far still many problems. According to our understanding, the main shaft of the molybdenum wire tube often breaks. Although various measures have been taken by the factories to improve the assembly process and increase Motor capacity, that is, the use of a larger diameter of the spindle, can not fundamentally solve the problem of spindle fracture.
