In order to analyze the material removal mechanism in the precision machining process of the cleavable brittle gallium oxide crystal, a diamond indenter was used in a model G200 nanoindenter to determine the nanomechanical properties of two main crystal faces (100) and (010) of β-Ga2O3, respectively. Based on the nanoindentation test, the crystal faces both have a "pop-in" phenomenon. The first pop-in loads are 4.31 mN and 5.42 mN, respectively. Based on the variable load nanoscratch test and atomic force microscopy, the crystal faces both have a "pile-up" phenomenon, and the plastic domain processing features appear in the middle of the scratching process. The scratching depths of the crystal faces are 96.5-576.8 nm and 84.6-421.6 nm, respectively
