9.1 General Information on Touch Probes
lT 120 Touch probe for tool measurement
The lT 120 is a triggering 3D touch probe for tool measurement and
inspection. The measured data can be stored in the central tool file
(depending on machine parameter MP 6507).
As with the TS 120 and TS 630, the triggering signal is generated by a
friction-free optoelectronic switch.
The lT 120 is generally mounted on the machine table. The exact
position within the REF system is defined in the TNC with machine
parameters. Thanks to its rugged design and high protection class
(IP 67). the probe is not affected by coolants or swarf.
Your TNC provides three cycles for this touch probe with which you can
measure the tool length and radius automatically - either with the
spindle rotating or stopped.
