一、问:精密型线切割机既然已达到微米级加工水平,是否可代替机械座标磨削加工?答:这是国内某些用户在考虑和选购机床时经常要问到的一个问题,也是国内外有关学者比较关注的一个问题。从目前国内外的一些实践和试验结果来看,基本上确立了下述的原则和结论,(见表1)。1)对于一般制品数量少、加工尺寸公差,形状精度不太严格的模具,采用线切割加工是比较有成效的。如果制品的数量大、加工公差严格、形状精度要求高时,采用座
First, Q: Since the precision wire cutting machine has reached the micron level of processing, can replace the mechanical coordinates of grinding? A: This is some domestic users in the consideration and purchase of machine tools often have to ask a question, It is also a problem that scholars pay more attention to at home and abroad. From the current domestic and foreign practices and experimental results, basically established the following principles and conclusions (see Table 1). 1) For a small number of general products, processing size tolerances, shape precision is not too strict mold, the use of wire cutting is more effective. If the number of products is large, the processing tolerance is strict, high precision requirements, the use of seat
