电火花成型表面的脉冲电化学光整加工技术基础实验研究

The Basic Experiment of EDM Surface Finished by Pulse Electrochemical Finishing Technology

在电火花成型表面上进行了脉冲电化学光整加工技术的实验研究。研究表明:脉冲电流密度、脉冲频率及极间间隙对表面光整效果有显著影响。通过实验给出了合适的工艺参数值。该工艺可将Ra1.6μm的普通电火花加工表面光整达到Ra0.042μm的表面。

The experiment shows that the pulse electrochemical finishing technology can improve the quality of the EDM surface and that the parameters, and the pulse current density, pulse frequency as well as the inner - electrode gap have remarkably effect on the finishing surface. The appropriate technological parameters are attained through this experiment and the EDM surface roughness is improved from Ra1.6μm to Ra 0. 042μm.
