今年初有一批废旧飞机轮的材料改割方块，但加工时却难以切割。经过摸索分析，排除了工作液、参数调整的问题，认为是材料导电性能较差，电蚀产物导电更差且粘结在工件上不易冲出，影响切割。有一次割了锡青铜工件约三万多平方毫米再割该种方块工件，竟切割很顺畅。后来换了水 Earlier this year, there was a batch of materials for cutting off used aircraft wheels, but cutting was difficult at the time of processing. After groping analysis, ruled out the working fluid, the problem of parameter adjustment, that is poor conductivity of the material, the conductivity of the electrical erosion worse and sticking on the workpiece is not easy to punch out, affecting the cutting. Once cut a tin bronze workpiece about thirty thousand square millimeters and then cut the square pieces of the workpiece, actually cut very smoothly. Later changed the water
