According to the requirements for the beam collimation system physical design of the rapid cycling synchrotron (RCS) of China Spallation Neutron Source (CSNS) , the primary collimator scrapers are made of 0.17±0.005mm thickness tungsten sheets. The machining of the tungsten sheet is very difficult because of high hardness and characteristics of the intrinsic brittleness of tungsten. In this paper, electropolishing processing methods is used for tungsten sheets processing. A special electropolishing device is designed according to the principle and process of electropolishing. The processing of tungsten sheets are finally completed after a series of experiments. And the rules of electropolishing for tungsten sheet processing are obtained according to the experimental results.
