摘要
本论文主要研究数控铣床的Z轴进给系统。数控铣床是数控机床中的典型机床,它对国家的机械行业的发展具有重要的贡献,其加工精度也决定了一个。其Z轴进给系统主要内容包括进给部件的计算与选用。进给部件首选滚珠丝杠螺母副,它拥有摩擦损失小、传动效率高、运动平稳、摩擦力小、灵敏度高、低速时无爬行,并且轴向刚度高、反向定位精度高精度稳定性好、磨损小、寿命长、维护简单、传动具有可逆性等特点,对于数控铣床的精确传动提供了保障,使其加工精度精度越来越高。

Abstract
In this thesis, the Z-C milling machine feed systems. CNC milling machine is a C machine tools in the machine bed, its country's machinery industry has an important contribution to the development of its precision also determine a country home level of development of machinery industry. The Z-axis feed system mainly includes the calculation of the ponents with the election use. ponents preferred ball screw pair, it has friction loss, high transmission efficiency, movement in stability, small friction, high sensitivity, low speed without crawling, and axial stiffness, high precision positioning reverse accuracy, good stability, wear and tear, long life, easy maintenance, transmission characteristics are reversible, the number of controlled milling machine to provide a guarantee for the precise transmission, making it more and more high precision accuracy.
