数控线切割机在加工模具的过程中,一般只能加工直刀口(即型腔壁垂直于凹模平面),当然加工斜刀口的线切割机也有单位搞过。但较难制造,难于推广。为了保证凸凹模之间较小的配合间隙,凹模落料就有困难,凹模往往容易胀裂,造成报废,为了解决这个困难,就需要 CNC wire cutting machine in the process of processing the mold, the general can only be machined straight knife (ie cavity wall perpendicular to the die plane), of course, oblique knife cutting machine also engaged in the unit. But more difficult to manufacture, difficult to promote. In order to ensure the punch and die with a smaller gap between the die die blanking difficulties, die tends to crack easily, resulting in scrapped, in order to solve this difficulty, you need
