双导向导轨即双导轨,它的两条导轨都具有导向性能。由于四个导轨面都是倾斜面,因而如何在修理中(指人工刮削)保证四个面即两条导轨的平直性尤其是平行性就比较困难。 就我所知关于这种导轨的修理工艺,大都比较繁杂,且不太可靠。通过反复总结和实践,我们摸索出一种新的办法,即简 Double guide rails are double guide rails, both of which have guide performance. As the four guide surfaces are inclined surface, so how to repair (referring to the manual scraping) to ensure that four planes that is the straightness of two rails, especially parallel is more difficult. As far as I know about the repair process of such rails, most of them are complicated and not reliable. Through repeated sum up and practice, we explore a new approach, Jane
