【Abstract】 Pulse electrochemical finishing (PECF) was applied to the teeth surface finishing and a new finishing process for teeth surface was developed. Parameters of the process, such as working current density, moving speed of cathode, scanning times of cathode, flowrate of electrolyte etc. were studied by experiments and the optimized process parameters were obtained. A gear (module: m =3mm, number of teeth: Z =33) is finished by this method and the results show that the roughness of teeth surface is reduced from Ra1.1μm to Ra0.09μm and the brightness of the teeth surface is increased greatly.更多还原
