6、质量稳定,且自动化程度极高,可减轻工人地体力劳动强度,大大提高了生产效率,特别值得一提地是数控机床可完成普通机床难以完成或根本不能加工地复杂曲面地零件加工,因而数控机床在机械制造业中地地位愈来愈显得重要.b5E2RGbCAP1.2数控机床地组成分类及特点1.2.1数控机床地组成数控机床一般由控制介质、数控装置、伺服系统和机床本体组成.1.控制介质：以指令地形式记载各种加工信息；2.数控装置：接受输入地加工信息,经数控装置运算处理,向伺服系统发出相应地脉冲；3.伺服系统：把数控装置地脉冲信号转换成机床运动部件地机械位移；用于实
7、现数控机床地进给伺服控制和主轴伺服控制.p1EanqFDPw25/25个人收集整理仅供参考学习4.机械系统：包括,主轴部分、进给系统、刀库和自动换刀装置(ATC)、自动托盘交换装置(APC)等.1.2.2数控机床地分类数控机床地品种和规格繁多,分类方法不一.根据不完全统计,目前已有近500种数控机床.DXDiTa9E3d根据数控机床地功能和组成,一般分为以下几类：按坐标轴数分类：一般数控机床,数控加工中心机床,多坐标轴数控机床；按特点分类：点位控制数控机床,直线控制数控机床,轮廓控制数控机床；按有无测量装置分类：开环数控系统
8、,半闭环数控系统,闭环数控系统；按功能水平分类：经济型,普及型,高级型.1.2.3数控机床地特点数控机床较好地解决了复杂、精密、小批、多变地零件加工问题,是一种灵活地、高效能地自动化机床,尤其对于约占机械加工总量80%地单件、小批量零件地加工,更显示出其特有地灵活性.概括起来,数控机床有以
