用于超高速加工的传动转数大多数情况下只能限制地被选用,因为机械式轴承的极限转数阻碍了优选。反之,主动式电磁轴承允许开辟较高的转数范围。
Transmission speed for ultra-high-speed machining can only be used for the most part, because the limiting revolutions of mechanical bearings are a deterrent. In contrast, active electromagnetic bearings allow to open up a higher range of revolutions.
