RTP20 indexing head
RTP20 indexing head with integral TP20 touch-trigger probe
2-axis head with 168 repeatable positions in 15 degree increments
- Indexing can be manual or automatic using the CMM motion
- TP20 module compatibility provides a wide range of force and length options to optimise machine performance and access capability
- Repeatable TP20 stylus module changing in each pre-qualified position without the need for re-qualification significantly enhances productivity
- Compatible with full range of TP20 stylus modules
- Modules can be changed manually or automatically with the MCR20 module change rack
- A built-in extension, together with existing extension bars, allow reach up to 168 mm (including maximum stylus length)
