The equipment used for this data is the VHX-600E ultra-depth of field microscope produced by keyence Company with a magnification of 20x. The observation objects are the surface macro morphology of the fitting parts of small-size specimens, the main parts include the interference fitting surface of the shaft diameter, the contact surface of the shaft shoulder and the fitting surface of the shaft sleeve. Through observation, the surface damage of the specimen under different rotation times can be determined, and the damaged part can be determined for further observation.
