At present, the processing method used for wire cutting of annular parts is to directly press the annular parts on the workbench for processing. This processing method is inconvenient to clamp. Since the pressing force requires the operator to operate directly on the equipment, the operator will spend a long time to adjust to the best state when leveling before wire cutting. The annular parts are prone to silk marks and very easy to make mistakes when they are distracted during processing. The workpiece is prone to fall after wire cutting, which will cause bruises and damage.
