钻孔机

The control system of NC drilling machine which takes the PLC as the main controller is used in drilling machine. It controls the aiguille moving from one positioning to another positioning relative to the positioning of the workpiece. The system consists of PLC, stepper motor driver, stepper motor, HMI, and so on.
