New Generation Tool touch probes with cable connection

(Preliminary information)


Together with the measuring cycles of the CNC control, the TT 160 tool touch probe enables the TNC to measure tools automatically while they are in the machine spindle. The control saves the values measured for tool length and radius in the central tool file. By inspecting the tool during machining you can quickly and directly measure wear or breakage to prevent scrap or rework. If the measured deviations lie outside the tolerances, or if the monitored life of the tool is exceeded, the control can lock the tool or automatically insert a replacement tool.
