Combined machining method based on magnetic fluid rubber tube mold core

According to the combined machining method based on the magnetic fluid rubber tube mold core, a device body is included, the device body comprises a grinding mechanism, a moving mechanism, an adjusting device and a sliding device, mechanical arms are arranged at the two ends of the top of the device body, and the grinding mechanism is arranged at one ends of the mechanical arms; a moving mechanism is arranged on one side of the device body, a groove is formed in the top of the device body, the top of the device body is slidably connected with the bottoms of sliding plates through the groove, the number of the sliding plates is two, a clamping plate is arranged on one side of each sliding plate, and mold core metal and rubber pipe casting materials are separated through a nitride film layer formed on the surface of a mold through nitriding treatment. According to the machining technology, the phenomenon that a rubber pipe casting material adheres to a mold is avoided, the problem that in the prior art, a mold
