我车间在3.4米立车上加工大于工作台直径的零件时(图1),采用如下两种方法控制零件高度: 一、如图2所示,在立柱上刻线来控制零件高度:以工作台面为基准,用划线盘把900毫米高度线刻在立柱2上,如图2a所示。然后,将板尺5左边接触找正好的零件,使板尺边缘与立柱上刻线重合,再用划针沿板 I workshop in the 3.4-meter vertical lathe processing more than table diameter parts (Figure 1), using the following two methods to control the height of the parts: First, as shown in Figure 2, engraved on the column to control the height of the parts: to work Bench top, with a scribe plate engraved 900mm height line on the column 2, as shown in Figure 2a. Then, touch the right side of the ruler 5 to find the right part, so that the edge of the ruler coincides with the engraved line on the column,
