Rubber part machining method

The invention relates to the technical field of machining, and discloses a rubber part machining method, which comprises the following steps: S1, sacrificial layers are respectively attached to the upper surface and the lower surface of a plate-shaped rubber blank, and the rubber blank and the sacrificial layers form a machining assembly; S2, the machining assembly is cut through a grinding wheel,so that a groove is formed in the rubber blank; S3, a grinding wheel is used for cutting the machining assembly along the periphery of the groove, and the rubber blank is cut through; and S4, the sacrificial layer is separated from the rubber blank. According to the rubber part machining method provided in the invention, the method is simple and highly practical, only the grinding wheel which isa machining tool low in cost and high in universality is needed, the machining cost and the machining difficulty are reduced, the service life of the machining tool is prolonged, the surface quality of machined parts is improv
