金属切削机床的主轴部件通常采用滚动轴承和滑动轴承(动压、静压和用空气润滑)做支承。上述轴承类型的应用范围取决于主轴的精度和速度参数,以及加工精度(加工另件的不圆度△r)见表1。
Metal cutting machine tool spindle components are usually used rolling bearings and plain bearings (dynamic pressure, static pressure and air lubrication) to support. The bearing type of application depends on the spindle accuracy and speed parameters, as well as machining accuracy (processing of other parts of the non-circularity △ r) in Table 1.
