Abstract: Aiming at the problems of complex structure, high quality and high price of the vibration polishing machine for electron backscatter diffraction sample preparation, a vibration polishing device based on the commercially available vibrating plate base was designed, and 2024 aluminum alloy and 2205 duplex stainless steel were selected for testing. The results show that the designed vibration polishing device had simple structure, simple operation and low price. The surface quality of the prepared electron backscatter diffraction sample was good, and the calibration rate of the electron backscatter diffraction test was high. It could accurately obtain the microstructure and orientation of metal materials.
