6ES7953-8LP20-0AA0 中国数控机床从无到有，到现在已经成为大的机床消费国和生产国。

从洋务运动到新中国建立前，中国机床工业处于萌芽阶段。19 世纪洋务运动期间，曾国藩“访募覃思之士、智巧之匠”，“觅制器之器与制器之人”。1863年容闳受曾国藩委派，历时两年从美国采购了第1 批机床设备，开始将西方现代机床工具引入中国。随后，江南机器制造总局自制出一批机床。到20世纪上半叶陆续建立了重庆机床厂、长沙机床厂、中央机器厂等一批机床厂，20世纪40年代，东北、上海、江浙等地又建立了一批机床制造企业，后来成长为沈阳三机、上海机床、济南一机、南京机床、无锡机床等国内机床厂。

从新中国成立到改革开放前(1949~1978 )的20年，中国机床工业发展可分为奠基阶段和大规模建设阶段。

1949年新中国成立后，中国机床工业开始进入快速发展时期。“一五”时期(1953~1957 )，在苏联专家指导下，第一机械工业部(简称“一机部”)按专业分工规划布局了被称为“十八罗汉”的一批骨干机床企业，还建立了以北京金属切削机床研究所(北京机床研究所的前身)为代表的被称为“七所一院”的一批机床工具研究机构。到1957年，一机部直属企业在机床、工具、磨料磨具和机床附件方面的产品产量都占 90％以上。相关产品产量的国内自给率达 80％左右。机床工具工业成为一个独立的工业部门，为后续发展奠定了基础，这一时期是中国机床工业的奠基阶段。
