小改造一台ＤＫ７７２５Ａ型线切割机丝架上下出水板与塑料管的接头如图１。因为有一转角，塑料管在转角处扁了，水流不通畅，直接影响加工的速度和加工精度。使用一段时间后，水中杂质沉淀，使得转角处经常堵塞，加工中因无水短路断丝。为了解决这一问题，用６ｍｍ铜管做... Small transformation A DK7725A wire cutting machine wire frame up and down the water board and plastic pipe joints shown in Figure 1. Because of a corner, the plastic tube at the corner of flat, the water flow is not smooth, a direct impact on the processing speed and processing accuracy. After using for a period of time, impurities in the water precipitate, making the corner often blocked, processing short circuit due to water short circuit. In order to solve this problem, with 6mm brass do ...
