APPARATUS FOR IDENTIFYING TOOLS AND FOR MANAGING TOOL DATA

摘要

In a machine tool such as a machining center or the like having an automatic tool changing apparatus (4), the tool holders (7) adapted to respectively hold the tools (6) provided for the automatic tool change are equipped with the transmitters (20, 20A) for transmitting the signals indicative of the tool date including the tool discrimination data of the tools. The receiver (30, 30A) to receive the transmitted signals from the transmitters is attached to the machine tool. When the transmitter approaches the receiver, the transmitted data is received by the receiver. The kind and the like of the tool held to the tool holder to which this transmitter is attached can be discriminated by the control unit of the machine tool on the basis of the received data. Thus, the tools can be certainly and easily managed and changed.
