The punching machine is composed of four parts that cooperate with each other to complete the punching process. Firstly, move the material to the scanning area of the camera of the automatic drilling machine. After the camera scans the image, it processes and sends a signal to the control part. After receiving the signal, the control part further processes and controls the action of the transmission part to make the punch move on the x-axis and y-axis on the plane. After the movement action is completed, the pneumatic part starts to work, and the solenoid valve controls the cylinder to punch. Automatic punching machine printing brush positioning hole, the whole action is done in one go, fast, accurate and efficient.
