The control system can logically process programs specified by control codes or other symbolic instructions, decode them, and express them in coded numbers. The information carrier is input into the CNC device, and the CNC device sends various control signals after calculation and processing to control the movement of the machine tool. The parts are automatically processed according to the shape and size required by the drawing. The current CNC machine tool spindle needs to pass through the round hole on the spindle when it is installed and fixed. Therefore, a drilling device for the spindle component of the CNC machine tool is needed to drill holes in it.
