摘　　要：介绍了自行研制的小型同步双主轴五轴联动精密加工系统,主体尺寸为680mm×620mm×400mm,主轴最高转速80 000r/min,跳动量小于2μm。利用激光干涉仪测得定位精度为5μm;对直线运动轴伺服系统进行设计,经伺服环调节及性能试验,获得优良的动、静态控制性能。采用直径0.2μm的端铣刀进行平面微铣削加工,获得表面粗糙度值为215nm。结果表明该系统充分具备微小零件的高效加工能力。A miniaturized twin spindle precise machining system is mentioned for miniaturied parts. The main part of the equipment has a base size of 680 mm×620 mm× 400 mm with a highest spindle speed of 80 000 r/min and its diameter run-out less than 2 μm. The positioning accuracy of micron is measured by a laser interferometer. And it describs the design of computerized numerical control （CNC） servo system of linear motion axis. The servo experiment results verify the excellent static and dynamic performance of the system. The machining tests include a plane with a surface roughness of 215 nm using a end milling cutter of Ф0.2 μm. The analytical results of these tests show that the system can fulfill the effi- cient machining of micro components.
