一、前言外立柱是 Z 3063钻床的关键件,毛重约900 kg。虽然形状简单,壁厚均匀,但由于有受力不平衡、上下滑动和旋转的摇臂与它配合,所以要求表面光洁度高,耐磨性好,硬度也要求较高,而且其不均匀度不应大于20H B。为了达到上述要求,将其材质定为高

First, foreword Column is the key part of Z 3063 drilling machine, gross weight about 900 kg. Although the shape is simple, the wall thickness is uniform, but due to the imbalance of force, up and down sliding and rotating rocker arm with it, so the requirements of high surface finish, good wear resistance, hardness also requires higher, and its non-uniformity is not Should be greater than 20H B. In order to achieve the above requirements, the material is set high
