CJX50-450 turning and milling composite machine tool: Giant Star can add corresponding power head combinations on the small cutting plate according to the customer's part processing technology requirements, to meet the needs of milling, drilling, tapping and other feature processing on the workpiece end face or circumference. The power head is driven by a servo motor through synchronous wheels, synchronous belts, or gear transmission to drive a single power shaft or a group of power shafts to rotate, driving the tool to machine the required features such as milling, drilling, and tapping on the end face or circumference of the workpiece, that is, to achieve simple turning and milling composite functions on a CNC lathe.
