Magnet machining system and machining method

The invention belongs to the technical field of magnet machining, and particularly relates to a magnet machining system and method. Comprising a magnetic bar trimming machine and a forming assembly, two moving seats are symmetrically installed on a machine table body of the magnetic bar trimming machine in a sliding mode, positioning pins are arranged on the moving seats, and the two positioning pins can clamp the two ends of a round bar; the forming assembly comprises a forming device and a groove pressing device, and a U-shaped arm is installed on the groove pressing device in a sliding mode. The method for machining the magnet through the magnet machining system comprises the following steps that firstly, a cylindrical blank is prepared through casting; secondly, the cylindrical blank is placed in a U-shaped arm on a magnetic bar finishing machine, and the two ends of the cylindrical blank are tightly jacked through two positioning pins; thirdly, the peripheral side of the cylindrical blank is trimmed; fou
