摘　　要：装配精度最终决定数控机床本身的加工精度,对于小型数控机床而言,在装配过程进行相关检测,根据结果通过相应的改进和完善,就能比较容易地确保装配精度;而对于大型机床,受条件限制,在自检的基础上,必须借助精密仪器进行检测验证;对于关键点的精度要求,还要辅以专业软件进行分析,并对结果进行比较,择优选取,以确保设备的装配精度。Assembly precision determines the machining precision of tile NC machine tools in the end, appoint to the small -scale NC machine tools, do some testing in the assembly processing, it could ensure assembly precision according to improving and perfecting. But the large -scale one, suffered from some conditions, based on the self-testing, with the accurate instrument to test and verify. As for precision re quiring of the key - points, it must be with the help of professional software, and comparing and choosing the exact results, to ensure the assembly precision of the machine tools.
