在金属切削加工过程中,我们经常遇到轴类及深孔类零件的切削加工,一般对台阶尺寸较长及深孔型零件不易测量,用钢皮尺又测量不准,而且加工效率较低,为此我厂采用了YDZ-1型车床纵向走刀测量装置。采用该装置一刀可准确加工出轴向长度尺寸,简称为“一刀准”。它具有使用简单方便,成本低, In the metal cutting process, we often encounter the shaft and deep hole parts of the cutting process, the general length of the step and the deep hole is not easy to measure the parts, steel tape measure is not allowed, and the processing efficiency is low, To this end I used the YDZ-1 lathe longitudinal walk measurement device. The device can be accurately processed with a knife axial length size, referred to as “a knife.” It has the use of simple and convenient, low cost,
