类似长轴之类的工件,有时会因受到热处理和机械加工等工序的影响而变弯。一般,校直工序是把工件安装在校正压力机的中间,用压力机的滑块从上向下压至中心线(图1中0—0)以下的工件弹回量处。
Workpieces like the long axis sometimes bend as a result of processes such as heat treatment and machining. In general, the straightening process is to install the workpiece in the middle of the calibrating press and push it down from the top of the press slider to the center of the workpiece (0-0 in Fig. 1).
