New Non-circular Piston Machining Center Study Based on Multiply Drive System RE-GMSM

The machining method of piston based on soft template has low machining precision and efficiency because of small drive electromagnetic force of lathe tool,slow respond speed and low motion rigidity.The non-circular piston machining center used a multiply drive system RE-GMSM as the tool power source was developed.This system has large driving force,fast response,and the system isn't affected by the environment.So it is a high precision machining system.The developed machining center can multi-step machining of non-circular piston,which improves the machining accuracy and efficiency of non-circular piston.
