在特殊零件上作精密线段的加工,采用刻刀刻线时,不易得到较规则整齐的线条。如果线段的基准是从一个孔中心出发,线段多,又是不等分的刻线,再加上线距的准确性高,就更难控制线段的准确性。 我厂加工X420K仿形锐的前比例尺和右比例尺(见图1和图2)时,是在民主德国OFD长度刻线机上 In the special parts for precision processing of the line, the use of engraved engraving, it is not easy to get more regular and neat lines. If the line is based on a baseline from the center of a hole, the line is more, but also unequal score, coupled with the high accuracy of line pitch, it is more difficult to control the accuracy of line segments. I plant processing X420K profile Rui before the former scale and right scale (see Figure 1 and Figure 2), is on the German Democratic OFD length scribing machine
