Additional information
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
