一、概述: 在生产实践中,经常碰到一些大厚度工件需要线电极切割。例如,80mm以上的厚冲模,100mm以上的直坒奇形零件,还有应力试验以及某些国防产品中厚达150mm的零件要求加工出0.15mm宽的窄缝狭槽等。但目前广泛使用的数控线电极切割机床,由于丝架的跨距较小,不能满足上述工艺要求。如能用小机床实现大厚度切割,这对于进一步扩大数控线电极切割的 First, an overview: In production practice, often encounter some large thickness of the workpiece needs wire cutting. For example, thick dies above 80 mm, straight-bladed odd-shaped parts over 100 mm, stress tests, and parts with thicknesses of up to 150 mm in some national defense products require narrow slot slots of 0.15 mm wide. But currently widely used CNC wire electrode cutting machine, due to the smaller span of the wire frame, can not meet the above process requirements. If you can use a small machine to achieve large thickness cutting, which is to further expand the NC wire electrode cutting
