An improved tool changing machining center adapted for boring, drilling, milling, tapping and tool changing operations under numerical control. The machining center, which may be built in both vertical and horizontal spindle configurations, has an automatic tool changer including a tool storage matrix, a swing spindle transfer device mounted on the matrix, and a two-handed transfer arm mounted on the headstock. It operates with current commercial tapered shank toolholders and utilizes the existing power drawbolt engagement structure of the toolholders to secure them during tool change. |
