The main structure of the Angle cutting machine is solid and durable by the overall welding of the steel plate, and only the standard machine with the tool can meet the processing needs of the general sheet metal processing plant. Without having to be like an ordinary punching machine, processing an Angle or a certain thickness of the workpiece has to make a set of molds, reducing the cost of use, reducing the trouble of frequent mold clamping of the ordinary punching machine, improving the work efficiency, reducing the labor intensity of workers, reducing the risk factor of workers, and low noise processing for the factory and workers to create a quiet working environment.
