<p>The machining center has a base, a frame and at least a machine tool mounted onto the frame, at least a tool magazine associated with the machine tool for changing the tool and a workpiece gripping and supporting member. The machining center comprises a movable vertical member adapted to support from the top the workpiece gripping and supporting member. The movable vertical member is adapted to position the workpiece gripping and supporting member in a first operative position in which the workpiece is automatically loaded onto or unloaded from the workpiece gripping and supporting member of the machining center and in a second operative position in which the workpiece is machined by the machine tool of the machining center. The gripping and supporting member is adapted to hold firmly the workpiece during the machining operation and support it from the top so that the chips formed by the machine tool during the machining operation fall downwards by force of gravity thereby clearing the machining area from the chips.</p> |
