3、术水平和现代化程度决定着整个国民经济的水平和现代化程度,数控技术及装备是发展高新技术产业和尖端工业（如：信息技术及其产业，生物技术及其产业，航空、航天等国防工业产业）的使能技术和最基本的装备。制造技术和装备是人类生产活动的最基本的生产资料，而数控技术则是当今先进制造技术和装备最核心的技术。当今世界各国制造业广泛采用数控技术，以提高制造能力和水平，提高对动态多变市场的适应能力和竞争能力。此外世界上各工业发达国家还将数控技术及数控装备列为国家的战略物资，不仅采取重大措施来发展自己的数控技术及其产业，而且在“高精尖”数控关键技术和装备方面对我国实行封锁和限制政策。全套图纸，加153893706数控机

4、床技术的发展自1953年美国研制出第一台三坐标方式升降台数控铣床算起，至今已有53年历史了。20世纪90年开始，计算机技术及相关的微电子基础工业的高速发展，给数控机床的发展提供了一个良好的平台，使数控机床产业得到了高速的发展。我国数控技术研究从1958年起步，国产的第一台数控机床是北京第一机床厂生产的三坐标数控铣床。虽然从时间上看只比国外晚了几年，但由于种种原因，数控机床技术在我国的发展却一直落后于国际水平，到1980年我国的数控机床产量还不到700台。到90年代，我国的数控机床技术发展才得到了一个较大的提速。目前，与国外先进水平相比仍存在着较大的差距。 总之，大力发展以数控技术为核心的先进制

5、造技术已成为世界各发达国家加速经济发展、提高综合国力和国家地位的重要途径。加工中心：是带有刀库和自动换刀装置的一种高度自动化的多功能数控机床。在中国香港，台湾及广东一代也有很多人叫它电脑锣。工件在加工中心上经一次装夹后，数字控制系统能控制机床按不同工序，自动选择和更换刀具，自动改变机床主轴转速、进给量和刀具相对工件的运动轨迹及其他辅助机能，依次完成工件几个面上多工序的加工。并且有多种换刀或选刀功能，从而使生产效率大大提高。加工中心由于备有刀库并能自动更换刀具，使得工件在一次装夹中可以完成多工序的加工。加工中心一般不需要人为干预，当机床开始程序后，它将一直运行到程序结束。关键词： 数控机床； 进
