本条数据采用的设备为ZYGO公司生产的NewView9000型3D表面光学轮廓仪，放大倍数为10x，对材料为45钢的废旧电机轴表面形貌进行测量，其测量部位为电机轴轴承位表面，获取其表面的机械加工痕迹的形貌数据，以建立电机轴轴承部位的粗糙模型。

The equipment used in this article is the NewView9000 3D surface optical profilometer produced by ZYGO Company with a magnification of 10x. The surface topography of the discarded motor shaft made of 45 steel is measured. The measuring part is the surface of the motor shaft bearing, and the topography data of the machining marks on the surface are obtained. To establish the rough model of motor shaft bearing position.
