Description:

Abstract:

An improved tool exchange arm for use in the automatic tool changer of a machining center adapted for boring, drilling, milling, tapping and tool changing operations under numerical control. The tool exchange arm may be incorporated in machining centers of either vertical or horizontal spindle configuration. It operates with current commercial tapered shank toolholders, is capable of precisely and securely positioning itself for engagement with the toolholders to be exchanged, and rotates quickly for tool exchange without sharp impacts at the extremities of its rotational stroke.
