Deep throat steel plate punching machine, also known as deep throat steel plate welding punching machine, is a type of punching machine that is generally used for punching sheet metal, such as the louvers in the middle of large electrical boxes and cabinets, and the peephole in the middle of anti-theft doors. As the distance between the material hole and the edge of the board is usually 300mm or more, while the throat depth of ordinary punching machines is only about 180-230, the wall panel blocks the sheet metal after it is put into the punching machine, making it impossible to achieve a distance of 300 or 500 between the material hole and the edge of the board. This requires the use of deep throat steel plate welding punching machine to achieve.
