Solutions for grinding machines | HEIDENHAIN

Thanks to its low radial probing force of just 0.2 N, the TS 750 enables exceptionally consistent probring accuracy over 360°. Due to this low probing force, the probing process itself has no effect on the measurement. Both touch probes exhibit a long service life of several million probing cycles even under the extreme grinding conditions.
