1、 CA6140 机床主轴数控加工工艺及夹具设计机床主轴数控加工工艺及夹具设计 摘摘 要要 随着我国国民经济的快速发展,数控机床在国内的应用越来越普遍,数控机 床作为高效率自动化装备越来越广大应用,数控技术是集计算机技术,自动控制 技术,测试控制技术,机械制造技术为一体的综合性高新技术,它将机械装备的功 能,可靠性,效率,质量及自动化程度等提高到一个新的水平。 数控机床的组成部件大致可以分为机械和电气两部分,机械部分通常称为机 床本体,它由对主轴组件的主运动系统,进给系统,支撑系统和自动换刀系统组 成。 主轴组件由主轴,主轴轴承和安装在主轴的传动件,密封件等组成。 主轴组件是机床实现旋转运动的执

2、行件,它直接带动工件或刀具参加表成形 运动是机床上的一个关键组件。 主轴组件是机床主要部件之一,它的性能,对整机性能有很大的影响,主轴直 接承受切削力,速度范围很大,所以对主轴组件的主要性能提出很高的要求。 在数控机床中，不论是数控车床、钻床还是铣床，其主轴是最关键的部件， 对机床精度起着至关重要的作用。 因此如何正确地设计机床主轴及其组件对机床加工精度的影响是至关重要 的。 关键词：关键词：数控机床；主轴组件；加工精度 CA6140 spindle of ncmachining process and fixture design ABSTRACT With the national eco
