Touch Probes

HEIDENHAIN probes feature hybrid technology with both radio and infrared signals.

HEIDENHAIN introduced two Touch Probes — the TS 460 for workpiece measurement and the TT 460 for tool measurement — featuring hybrid technology, and offering radio and infrared signal transmissions. The dual signal transmission of these new touch probes enables the user to select either mode, combining the advantages of radio or of infrared signals. The radio transmission uses the 2.4 GHz frequency band, which does not require a license, and has 16 channels. The range is usually 15 m, but much larger ranges are possible under ideal circumstances, the company says. The infrared transmission has a range of 7 m.

On both the TT 460 and TS 460, the optical sensor is free of wear, and so provides the specified probing reproducibility even after a large number of probing processes (5 million switching cycles during type testing). And the compact design makes it possible to use these touch probes even where installation space is limited. The smaller contours of the TS permit much freedom when tilting into position. The TS workpiece touch probes also have blower jets for cleaning the workpiece, either with coolant or compressed air.
