目前,许多单位普遍采用冷检方法来测量,验收普通车床主轴与尾座中心高,冷检是在机床处于静止常温状态下进行的。验收标准是尾座中心必须高于主轴中心+0.02毫米。冷检验收方法有两个弊端:一、采用冷检验收的机床所加工出来的零件,经我们多次测量,往往外径与内径同心度超差,一 At present, many units commonly used cold inspection method to measure, acceptance of ordinary lathe spindle and tailstock center high, cold inspection is carried out in the machine at a standstill temperature. The acceptance criteria is that the tailstock center must be +0.02 mm above the spindle center. Cold inspection method has two drawbacks: First, the use of cold inspection machine received by the processing of parts, by our many measurements, often outside diameter and diameter concentricity difference, a
