电解加工是近二十年发展起来的一门新的加工工艺。由于它具有一系列优点,被广泛用于汽车、拖拉机、航空和宇航等工业部门,用来完成各种异形零件、型孔、整体叶轮、叶片、炮管膛线以及各种模具的加工。由于电解加工是在阴极和工件之间只有0.1—0.3毫米的间隙上加低的直流电压(10伏至20伏),流过大电流(几千安培至几万安培),同时通过电解液的电化学作用实现加工。因此,在这样小的间隙中,如果混进有导电的微粒或不导电的绝缘物、以及工艺参数选择不合理、进给速度太快和机床刚性不好等等原因,往往就在加工间隙中产生各种故 Electrolytic processing is a new process developed in recent 20 years. Because of its range of benefits, it is widely used in the automotive, tractor, aerospace and aerospace industries to complete a wide range of profiled parts, holes, integral impellers, vanes, gun barrel rims, and a variety of mold processes. Since electrolytic machining adds a low DC voltage (10 V to 20 V) to the gap of only 0.1-0.3 mm between the cathode and the workpiece, a large current (thousands of Amperes to tens of thousands of Amperes) flows through the electrolyte Electrochemical processing. Therefore, in such a small gap, if mixed with conductive particles or non-conductive insulation, and the choice of process parameters is not reasonable, the feed rate is too fast and the machine is not good rigidity and other reasons, often in the processing gap Produce a variety of so
