TP20 system
TP20 / TP20NI

- A kinematic, module changing touch-trigger probe system for manual and DCC CMMs
- Rapid exchange (manually or automatically) between stylus configurations without the need to re-calibrate
- Direct replacement for TP2-5W probe
- A choice of seven stylus modules, giving 5 or 6-axis operation, allow optimisation of probe and stylus performance for each application
- Easily retrofitted to all Renishaw standard probe heads (M8 or autojoint) and compatible with existing TTP interfaces
- Metrology performance equivalent to TP2-5W probe
- Compatible with the full range of Renishaw probe heads and accessories
System components
TP20 probe body
Houses one half of the highly repeatable magnetic kinematic
coupling- Contains a magnetic proximity switch to inhibit triggering of
the probe during automatic module changing with MCR20
NOTE: If the probe is operated close to magnetised parts/clamping etc, the probe trigger may become inhibited. Countermeasures include the use of long styli, stylus extensions or body orientation to increase the distance to the magnetic source. Alternatively, use the TP20NI probe body.
TP20NI probe body
- Probe body not affected by magnetic fields
- Probe trigger must be inhibited through software during change cycles using the MCR20
