测量数显系统在国内机械加工工艺中的应用逐渐广泛,但测量长度都在3米范围之内。我厂在上海市机床研究所协助下,已将该所试制成功的长磁栅测量数显系统应用在TR—100大型精密车床上。该系统测量长度在5米以上(由于受机床的限制,有效测量长度为4.3米),并首次进行长磁栅系统现场录磁的工艺试验,对机床误差实现了一定的补偿,从而提高了测量精度。在有效测量范围内,最大峰峰误差不大于0.03毫米,是 Measuring digital display system in the domestic mechanical processing technology gradually widespread, but the measurement length is within 3 meters. With the help of Shanghai Machine Tool Research Institute, our factory has successfully applied the trial production of long magnetic grid measuring digital display system to the TR-100 large-scale precision lathe. The measuring length of the system is more than 5 meters (due to the limitation of the machine tool, the effective measuring length is 4.3 meters), and the first time the long magnetic grid system magnetic recording process test, the machine error to achieve a certain degree of compensation, thereby enhancing the measurement Accuracy. In the effective measurement range, the maximum peak-to-peak error of not more than 0.03 mm, is
