数控金切机床高速主轴的性能，在相当程度上取决于主轴轴承及其润滑。滚动轴承由于刚度好、精度可以制造得较高、承载能力强和结构相对简单，《联系人；欧先生》

《邮箱：2479261344@.com》不仅是一般切削机床主轴的，也受到高速切削机床的青睐。从高速性的角度看，滚动轴承中角接触球轴承，圆柱滚子轴承次之，圆锥滚子轴承最差。
角接触球轴承的球(即滚珠)既公转又自转，会产生离心力Fc和陀螺力矩Mg。随着主轴转速的增加，离心力Fc和陀螺力矩Mg也会急剧加大，使轴承产生很大的接触应力，从而导致轴承摩擦加剧、温升增高、精度下降和寿命缩短。因此，要提高这种轴承的高速性能，就应想方设法抑制其Fc和Mg的增加。从角接触球轴承Fc和Mg的计算公式得知，减少球材料的密度、球的直径和球的接触角都有利于减少Fc和Mg，所以现在高速主轴多使用接触角为15°或20°的小球径轴承。可是，球径不能减小过多，基本上只能是标准系列球径的70%，以免削弱轴承的刚度，更关键的还是要在球的材料上寻求改进。
与GCr15轴承钢相比，氮化矽(Si3N4)陶瓷密度仅为它的41%，用氮化矽制作的球要轻得多，自然在高速回转时所产生的离心力和陀螺力矩也要小得多。与此同时，氮化矽陶瓷的弹性模量和硬度是轴承钢的1.5倍和2.3倍，而热膨胀系数仅为轴承钢的25%，这既可提高轴承的刚度和寿命，又使轴承的配合间隙在不同温升条件下变化小，工作可靠，加之陶瓷耐高温且不与金属发生粘咬，显然用氮化矽陶瓷制作球体更适合进行高速回转。实践表明，陶瓷球角接触球轴承与相应的钢球轴承相比速度能提高25%~35%，不过价格也要高一些。
