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，对从废旧45钢电机轴上沿径向切割，在剖光后进行测量，测量部位为电机轴的内部截面，一方面为测量材料内部的杂质直径，另一方面为判断剖光表面是否满足硬度测量的要求。

The equipment used in this article is the NewView9000 3D surface optical profilometer produced by ZYGO Company with a magnification of 10x. It cuts the waste 45 steel motor shaft along the radial direction and measures the internal cross section of the motor shaft after profile. On the one hand, it measures the diameter of impurities inside the material. On the other hand, it is to determine whether the surface of the profile meets the requirements of hardness measurement.
