TP20

Compact module changing touch-trigger probe, which allows the use of a range of stylus configurations and extensions to access features on complex parts.

About TP20

The TP20 is a compact 5-way, or 6-way, kinematic touch-trigger probe system. The two-piece design, comprising probe body and detachable stylus module(s), connected using a highly repeatable magnetic kinematic coupling.  This provides the facility to change stylus configurations either manually or automatically without the need for requalification of the stylus tips, thereby giving significant time savings in inspection routines.

Modules offering a range of trigger forces allow the probe performance to be best matched to the measurement task. A set of probe extensions is also available, as is a 6-way module.  The stylus mounting thread accepts styli from the Renishaw M2 range.

The TP20 system is easily retrofitted and is compatible with existing touch trigger probe interfaces, extensions and adaptors.

System components

The system components are:

• TP20 probe body
• TP20 probe module - seven variants allow optimisation to suit application
• MCR20 module changing rack - automatic operation
• MSR1 module storage rack - manual operation
• Suitable for interfacing with Renishaw's PI4-2, PI7-2 or PI200

TP20 specification

Probe 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 - 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 - 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 - 60 mm
EF - Extended force		Large stylus assemblies or where vibration causes spurious 'air' triggers	XY: 0.1 N Z: 3.2N Stylus: 10 mm	10 - 60 mm
6W - 6-way		Measurement in the –Z direction - e.g. undercuts	XY: 0.14 N Z: 1.6N Stylus:  10 mm	10 - 50 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 - 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 - 50 mm

Changing racks

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.

The MSR1 module storage rack safely holds up to six modules and eases the operators task where manual changing is performed, aiding productivity.
