机床主轴  机床上带动工件或刀具旋转的轴。通常由主轴、轴承和传动件(齿轮或带轮)等组成主轴部件。除了刨床、拉床等主运动为直线运动的机床外,大多数机床都有主轴部件。主轴部件的运动精度和结构刚度是决定加工质量和切削效率的重要因素。衡量主轴部件性能的指标主要是旋转精度、刚度和速度适应性。①旋转精度:主轴旋转时在影响加工精度的方向上出现的径向和轴向跳动(见形位公差),主要决定于主轴和轴承的制造和装配质量。②动、静刚度:主要决定于主轴的弯曲刚度、轴承的刚度和阻尼。③速度适应性:允许的最高转速和转速范围,主要决定于轴承的结构和润滑,以及散热条件。    20世纪40年代以前,大多数机床的主轴采用单油楔的滑动轴承。随着滚动轴承制造技术的提高,后来出现了多种主轴用的高精度、高刚度滚动轴承。这种轴承供应方便,价格较低,摩擦系数小,润滑方便,并能适应转速和载荷变动幅度较大的工作条件,因而得到广泛的应用。但是滑动轴承具有工作平稳和抗振性好的优点,特别是各种多油楔的动压轴承,在一些精加工机床如磨床上用得很多。50年代以后出现的液体静压轴承,精度高,刚度高,摩擦系数小,又有良好的抗振性和平稳性,但需要一套复杂的供油设备,所以只用在高精度机床和重型机床上。气体轴承高速性能好,但由于承载能力小,而且供气设备也复杂,主要用于高速内圆磨床和少数超精密加工机床上。70年代初出现的电磁轴承,兼有高速性能好和承载能力较大的优点,并能在切削过程中通过调整磁场使主轴作微量位移,以提高加工的尺寸精度,但成本较高,可用于超精密加工机床。
