It is indicated from the results that effected by the highfrequencygroup pulse power, higher machining quality is obtained by choosing higher main pulse frequency.
结果表明，在高频群脉冲电源作用下，选择较高的主脉冲频率，可获得良好的加工质量。

Meanwhile, a new electrochemical machining power supply is introduced in detail-a power supply for highfrequencygroup pulse electrochemical machining used in the micro-machining.
另外，还详细介绍了一种新型电解加工电源：用于微小型零件加工的高频群脉冲电解加工电源。
