　　记者日前从有关方面了解到,作为广州机床工具行业协会常务副会长企业,广州市敏嘉制造技术有限公司2012年在专用数控磨床行业取得重大突破:敏嘉首次作为责任单位,承担了国家高档数控机床和基础装备重大专项:“弧面凸轮加工工艺研究及弧面凸轮五轴加工中心、弧面凸轮六轴磨削中心”。该项目的目标是研究刀库换刀机构弧面凸轮加工工艺,开发具有自主知识产权的弧面凸轮制造专用设备,满足功能部件企业需求,提升国产刀库设计制造水平。 2.1 常用玻璃加工方法及其存在的问题 平板玻璃的磨边加工，玻璃棱边被加工成一定的形状，如平直边、圆边或C形边等，通常采用能在一次性操作中完成的生产线。玻璃的粗磨、半精磨、精磨、抛光等由装在多达六个工位上的金刚石砂轮连续进行。对于玻璃工艺制品和水晶玻璃的装饰性磨削加工，高精密外圆磨床厂家,数控外圆磨床，则多用手动或在多轴自动专用磨床上进行装饰性加工。光学透镜的粗磨，一般在专用磨床上采用轮缘为圆弧的杯形砂轮。 目前，由于机床主轴在加工玻璃时，高精密外圆磨床厂家,大型外圆磨床价格，自身不能对刀具所受外力的变化快速地进行自我调整，致使玻璃产品和刀具容易破碎。
