Abstract
A tool exchange apparatus comprises a first tool exchange arm for removing a previous tool mounted on a machine tool and returning the removed previous tool on a tool magazine and a second tool exchange arm for removing a new tool arranged on a tool magazine and setting the removed new tool to the machine tool, so that tool exchange operation can be achieved continuously. Further, each tool exchange arm comprises an upper finger and a lower finger. The upper finger is movable relative to the lower finger in order to remove only a lower tool (e.g. die) without exchanging an upper tool (e.g. punch).
