| Abstract: | 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 ≈0.2 μm.The analytical results of these tests show that the system can fulfill the efficient machining of micro components. |
