RTP20 (Automated Indexable Probe Head)
The RTP20 probe offers a cost effective solution for customers that require automatic indexing on CNC machines. Modelled on the MH20i body, the RTP20 uses the CNC motion of the CMM to position itself using a post mounted to the bed of the machine. Like the MH20i it is able to index from 0° to 90° in the A axis and through 360° in the B axis to be moved to 168 repeatable positions in 15-degree increments and uses a TP20 stylus module, which in turn accepts the M2 range of styli. The RTP20 is also fully compatible with the MCR20 change rack to provide an option that provides both automatic stylus changing as well as automatic indexing.
RTP20 offers low-cost ‘motorised’ head functionality with integral TP20 touch-trigger probe
RTP20 probe key benefits
Productivity
Improved productivity is achieved via probe module changing and automated indexing without the need for constant re-qualification.
Increased reach and flexibility
A built-in extension together with existing extension bars allow reach up to 168 mm (including maximum stylus length).
Automation
Utilising the CMM motion to lock and orientate the head, together with the MCR20, provides a fully automated system.
Crash protection
TP20 modules have overtravel in all directions. The magnetic mounting provides additional crash protection in X and Y.
TP20 Stylus Modules
A range of seven, application specific, probe modules is available and are identified by coloured caps.
|
Module |
Application | Trigger forces* | Stylus lengths | |
|---|---|---|---|---|
|
SF- Standard force |
|
Suited to the majority of applications |
XY: 0.08 N Z: 0.75 N Stylus: 10 mm |
10 mm to 50 mm GF |
|
LF- Low force |
|
Low trigger forces applications - e.g. rubber seals |
XY: 0.055 N Z: 0.65 N Stylus: 10 mm |
10 mm to 30 mm |
|
MF- Medium force |
|
Where a higher trigger force than standard is required |
XY: 0.1 N Z: 1.9 N Stylus: 25 mm |
10 mm to 60 mm |
|
EF- Extended force |
|
Large stylus assemblies or where vibration causes spurious 'air' triggers |
XY: 0.1 N Z: 3.2N Stylus: 50 mm |
10 mm to 60 mm |
|
6W- 6-way |
|
Measurement in the –Z direction - e.g. undercuts |
XY: 0.14 N Z: 1.6N Stylus: 10 mm |
10 mm to 30 mm |
|
EM1 STD- 50 mm extension |
|
Majority of applications requiring a 50 mm extension |
XY: 0.08 N Z: 0.75 N Stylus: 10 mm |
10 mm to 50 mm |
|
EM2 STD- 75 mm extension |
|
Majority of applications requiring a 75 mm extension |
XY: 0.08 N Z: 0.75 N Stylus: 10 mm |
10 mm to 50 mm |
MCR20 Change Rack
The MCR20 probe module changing rack is designed to securely hold stored modules for rapid automatic changing, and to protect them from airborne contaminants which may be present within the working environment.
