RTP20 indexing head with integral TP20touch-trigger probeThe RTP20 probe head allows the integral TP20 probe to be moved to168 repeatable positions in 15-degree increments using both A and Baxes, requiring a one-time qualifi cation for each stylus tip position. Thiseliminates the need for costly time consuming requalifi cation routines,ensuring fast throughput for part inspection.Automated indexing of the RTP20 probe head is realised throughan innovative process which uses the motion of a CMM to achieve‘motorised’ head style operation.An RTP20 integral TP20 probe mount optimises the working volumeof the CMM and provides compatibility with all existing TP20 modules.Although modules can be changed manually, the RTP20 can be usedwith the MCR20 module change rack to allow fully automated modulechanging.Manual probe headswith integral TP20 stylus module mount6-1The RTP20 can be installed on new and existing measuring machines viaa shank mounting, involving just the initial qualifi cation of each measuringposition and stylus combination.Ø48 mm (1.89 in)47 mm(1.85 in)86.3 mm(3.40 in)RTP20 features and benefits:• Improved productivity is achieved via probemodule changing and automated indexing,without the need for constant requalifi cation.• A built-in extension together with existingextension bars allow reach up to 168 mmA-axis0° - 90°21 mm to 75 mm(0.83 in to 2.95 in)(including maximum stylus length).• Utilising the CMM motion to lock, unlockand orientate the head, together with theMCR20, provides a fully automated system.Please refer to page 5-3for probe compatibilityinformationB-axis±180°5.7 mm (0.22 in)• TP20 modules have overtravel in alldirections.
