SUC8109 double-face horizontal five-station CNC combined machine for counterboring and reaming center holes of camshafts, tapping, deburring and blowing, adopts feed mechanism of one station up for loading and five stations down for unloading. The respective five sets of servomechanisms on both sides can machine (handle with) work-piece simultaneously, which are applied to counterboring center holes at both ends of camshaft, tapping screw holes at both ends, turning center taper holes at both ends, deburring holes at both ends and blowing out the chips caused during machining. The above-mentioned processes can be finished in one setting. The machine also features high automaticity, high rigidity, high accuracy and user-friendly operation, as well as suitable for volume production.
