数控线切割工艺问世以来,不但在提高模具生产质量和缩短制造周期等方面收到显著效果,而且在解决工装制造的其他技术问题方面也起到重要作用。通过增设适当的辅助装置,数控线切割还可以进行一般机床难以实现的特形零件的加工。经过几年的实践,我们在利用线切割加工特形零件方面取得一些经验,简介如下。1 切割回转零件如图1中2所示,工件是一碾轧合金工装中的关键零件。其工作部位尺寸精度要求如图2所示,材料 Since the advent of NC wire cutting technology, it has not only achieved remarkable results in improving the quality of mold production and shortening the manufacturing cycle, but also played an important role in solving other technical problems in tooling manufacture. By adding appropriate auxiliary devices, CNC wire cutting can also be difficult to achieve in general machining of special shape parts. After several years of practice, we have some experience in the use of wire cutting special shape parts, as follows. 1 cutting rotary parts shown in Figure 1, 2, the workpiece is a rolling mill key components in the tooling. The size of its work site accuracy requirements shown in Figure 2, the material
