RFID identification of metal interchangeable parts for machine tools

A machine tool comprises a first component, for example a dressing spindle (3), and at least one second component, for example a dressing wheel (1), which is removably and/or movably arranged on the first component. The first component has a first antenna coil for a wireless signal transmission, and the second component has a second antenna coil. The two components together delimit a cavity which is completely surrounded by metal. The first antenna coil and the second antenna coil are arranged together in the cavity. This forms a metal-protected radio link (26.1) between the first antenna coil and the second antenna coil, which radio link is protected from harmful external influences. 种机床，包括：第构件，例如修整主轴(3)；和至少个在所述第构件上能移除和/或能运动地设置的第二构件，例如修整砂轮(1)。所述第构件具有用于无线地传输信号的第天线线圈，并且所述第二构件具有第二天线线圈。这两个构件共同地对空腔限界，所述空腔基本上完全地由金属围绕。所述第天线线圈和所述第二天线线圈共同地设置在所述空腔中。以这种方式形成在第天线线圈和第二天线线圈之间的金属保护的无线电线路(26.1)，所述无线电线路被保护以免受有害的外部影响。
