ABSTRACT:
A tool holding device for use in a printed circuit board processing machine is provided with a record which is capable of storing data concerning the states of tools held on the tool holding device and data concerning processing conditions and which enables reading and updating of the recorded content through a communication with an external control device. Necessity for renewal of data registered in the NC device, which has to be executed in the known apparatus each time the tool holding device is exchanged, is eliminated thereby improving the rate of operation of the printed circuit board processing machine. In addition, the present invention enables an easy automatic replacement of tools when the lives of the tools are expired.
