RTP20 indexing head with integral TP20 touch-trigger probe
The RTP20 probe head allows the integral TP20 probe to be moved to 168 repeatable positions in 15-degree increments using both A and B axes, requiring a one-time qualification for each stylus tip position. This
eliminates the need for costly time consuming requalification routines, ensuring fast throughput for part inspection.
Automated indexing of the RTP20 probe head is realised through an innovative process which uses the motion of a CMM to achieve ‘motorised’ head style operation.
An RTP20 integral TP20 probe mount optimises the working volume of the CMM and provides compatibility with all existing TP20 modules. Although modules can be changed manually, the RTP20 can be used
with the MCR20 module change rack to allow fully automated module changing.
The RTP20 can be installed on new and existing measuring machines via a shank mounting, involving just the initial qualification of each measuring position and stylus combination.
RTP20 features and benefits:
- Improved productivity is achieved via probe module changing and automated indexing, without the need for constant requalification.
- A built-in extension together with existing extension bars allow reach up to 168 mm (including maximum stylus length).
- Utilizing the CMM motion to lock, unlock and orient the head, together with the MCR20, provides a fully automated system.
- TP20 modules have overtravel in all directions. The magnetic mounting provides additional crash protection in X and Y.
