摘　　要：以实现高精度、高效率、高自动化程度加工为目的,基于高精度平面磨床MGK7160的加工系统,详细分析了加工规划控制、计算机辅助制造软件系统开发、砂轮修整及动平衡、在位测量等关键配套工艺技术。在已有设备及配套工艺基础上利用400#粒度金刚石圆弧砂轮,实现口径400mm×400mm平面光学元件的加工,获得了较好的加工精度,验证了机床及加工技术系统的可靠性。Ultra precision grinding with diamond wheel is widely used for manufacture of large scale optical lens, especially for deterministic batch processing. This paper presented a surface grinding system based on large-scale NC precision surface grinder（MGK7160） to obtain the high machining accuracy, efficiency and automatic level. Then some key technologies, such as diamond wheel truing, dynamic balance, on-machine measurement, CAM software were detailedly realized. The experiments for 400mm＊400mm optical lens using 400# grinding wheel were carried out, and the results well reflect that the developed grinding system based on surface grinding machine can perform precision machining of large-scale advanced optical elements with fine reliability.
