  • Machining center for processing center groove and center groove processing method of a crankshaft using the same
    Patent number: 11697163
    Abstract: A machining center for machining a center groove on a pulley and a flange formed at opposite ends of a crankshaft of a vehicle includes a measurement unit configured to measure a moment of the crankshaft when the crankshaft is loaded and actuated, a control unit configured to calculate an imbalance amount of the crankshaft and to derive center drill coordinates for removing the imbalance amount, a compensation unit mounted in a base frame and configured to compensate a position of the crankshaft by rotating first and second rotating elements based on the center drill coordinates inputted from the control unit when the crankshaft is transported and clamped by a clamping system, and a machining unit configured to machine the center groove in the pulley and the flange of the crankshaft.
