我厂原有一台游标卡尺底版刻线机,由于工作台传动丝杆严重磨损,在500毫水的最大加工长度上的累积误差达到0.06毫米,已不能用于刻制长度超过80毫米的工件。刻线机一般都配备误差修正(补偿)机构,但过去由于缺乏在机床上直接测量工作台实际移动量的有效手段,修复工作难以进行。1987年9月在这台机床上安装了一套测量长度为500毫米,分辩率为0.001毫米的光栅数字显示测量系统,能直接显示出机床工作台的实际位移量。由于掌握了有效的数据,修复工作得以
I had a Vernier caliper original engraving machine, due to serious wear and tear on the table drive screw, the cumulative error of the maximum processing length of 500 milliliters of water reached 0.06 mm, can not be used to engrave the length of more than 80 mm of the workpiece. Grooving machines are generally equipped with error correction (compensation) mechanism, but in the past due to the lack of direct measurement of the actual movement of the table on the machine effective means of repair work difficult. In September 1987, a set of grating digital display measuring system with a measuring length of 500 mm and a resolution of 0.001 mm was installed on this machine tool, which directly shows the actual displacement of the machine table. Due to the availability of valid data, repair work was done
