tp20

Kinematic probe system

with module changing

The TP20 touch trigger probe enables manual or automatic

stylus changing without re-qualification. This allows complex

part measurement, where a range of stylus configurations is

needed to access all features on the part.

Modules offering a range of trigger forces allow the probe

performance to be accurately matched to the measurement

task. A set of probe extensions is also available, as is a 6-way

module, allowing the inspection of features with restricted

access.

The TP20 can be used on a wide range of Renishaw’s manual

or motorised probe heads, either by direct mounting using the

standard M8 thread or alternatively, by using a PAA adaptor to

connect with the autojoint on the head.

The optional MCR20 module changing rack can store up to

six probe modules for automatic changing under

measurement program control. The probe is automatically

disabled during the change cycle.

The MSR1 can store up to 6 probe modules for manual stylus

changing and safekeeping when not in use.

Available modules:

LF = low force

(green cap)

Suited to applications that require a low trigger force.

SF = standard force

(SF, EM1 and EM2)

(black cap)

Suited to a majority of applications.

MF = medium force

(grey cap)

For use when a higher trigger force higher than ‘SF’

is required.

EF = extended force

(brown cap)

Required with large stylus assemblies. Also, to

eliminate spurious triggers due to machine vibration

ａnd acceleration.

6 W = 6-way probe
