Abstract： In order to solve the problems of mould laser enhanced surface's high hardness，wear resistance and local hardness difference，a new technique of abrasive solidified balloon polishing was proposed to achieve the efficient，precision and automatic polishing. This technique made free abrasive solidify out of the rubber balloon surface by polymer binder，so that the abrasive group could obtain more stable support，form more effective and smooth cutting effect. Consideration of the abrasive solidified balloon's performance requirements，a process method that makes abrasive solidify out of the acid silicone sealant surface by SBR was established. With the robot auxiliary platform，the abrasive solidified balloon was tested. The experimental results show that by controlling the uniformity of abrasive solidified balloon，and strengthening the bonding effect of composite layer，it could reduce the surface roughness，and improve processing efficiency，which lays a solid foundation for the mold efficient polishing.
