ABSTRACT:
A tool spindle in movable is a forward stroke toward a workpart and in a rearward stroke. A sensing device senses whether a tool chucked on the forward end of the spindle is damaged. A tool changer mechanism enters the rear of the spindle as the spindle moves rearwardly and inserts a replacement tool for the damaged tool in response to a signal from the sensing device indicating the tool is damaged. The next forward stroke of the spindle machines the workpart with the replacement tool. A replacement tool magazine and tool transfer mechanism are carried on a common slide with the spindle and are movable relative to the tool changer mechanism to transfer a replacement tool from the magazine to the tool changer mechanism.
