The workbench consists of a base and a pressing plate. The base is connected to the clamping plate through a hinge. The base is composed of a housing, a coil, and a cover plate. The coil is placed in the depression of the housing, and the cover plate covers the top of the depression. When in use, an electric current is passed through the coil by a wire. After being energized, an attractive force is generated on the pressing plate, thereby realizing the clamping of the thin plate between the pressing plate and the base. Due to the use of electromagnetic force clamping, the pressing plate can be made according to various workpiece requirements, and workpieces with side walls can be processed, and the operation is also very simple.
