三、国外组合机床动力部件技术发展现状国外组合机床动力部件技术的发展,在1960年代中叶是相当缓慢的,直到六十年代末七十年代初,基本上没有太大的发展。在驱动方面仍然以液压、电气机械、气动液压为主。但六十年代中叶在动力部件上出现的一些新技术,例如动力部件的组合型式、气动液压驱动、静压支承、齿盘式分度定位、液压马达等,在目前获得了普遍应用。
Third, the status quo of foreign combination machine tool power components The development of foreign combination machine tool power component technology in the mid-1960s is quite slow until the late sixties and early seventies, basically not much development. In the drive is still hydraulic, electrical machinery, pneumatic-based. However, some new technologies that appear on the power components in the mid-1960s, such as the combination of power components, pneumatic and hydraulic drive, hydrostatic support, gear-plate indexing and hydraulic motors, are currently widely used.
