光电控制微位移镗刀头

Electrophoto controlling tiny displacement of boring cutter head

本文讨论了镗刀头微量位移的实现及其信号传输方式，提出了一种光电控制电致伸缩微位移镗刀头执行系统，实验结果表明该系统补偿精度满足要求。

The realization of tiny displacement of boring cutter head and the way of displacement signal transmission are discussed in this paper. An executive system of electric- expanding and contracting tiny displacement of boring cutter head, which is electrophoto controlled, is proposed. The result of experiment shows that compensating accuracy of the system is satisfactory.
