目前国内生产的数控线切割机的传丝机构大部分是单丝筒式,另一种是双丝轮式。我们对这两种结构进行比较,扬长避短,在一台旧的双丝轮式线切割机上做了如下改进: 1.去掉三根硬质合金棒电极(包括导电用的和断丝报警用的).避免与钼丝直接摩擦。 2.导电方式改由轴端进电。具体做法
At present, most of the transmission mechanism of CNC wire cutting machine in China is a single wire barrel type, the other is double wire wheel type. We compare these two structures to avoid weaknesses and make the following improvements on an old twin wire wheel cutting machine: 1. Remove the three carbide rod electrodes (including conductive and wire break alarms). Avoid direct friction with molybdenum wire. 2. Conductive way into the shaft end by electricity. specific methods
