Point
The fully automated system enables high-efficiency, high-precision crankshaft processing on a multitasking machine.
On the WT-300, counterweight end faces, journal sections, and shaft end-face processing—including hole drilling—are performed. End-face processing is stabilized using a steady rest attached to the lower turret. Once completed, the crankshaft is unloaded by a robot and automatically transported to the Super NTJ.
On the Super NTJ, the B-axis swiveling turret is utilized for deep hole drilling of oil holes and keyway milling, all achieved in a single chucking. Furthermore, phase detection by the NT Work Navigator and smooth transport using the temporary stand on the lower turret enable high-quality processing in a short time.
