TP20 system

TP20 / TP20NITP20 standard force module

  • A kinematic, module changing touch-trigger probe system for manual and DCC CMMs
  • Rapid exchange (manually or automatically) between stylus configurations without the need to re-calibrate
  • Direct replacement for TP2-5W probe
  • A choice of seven stylus modules, giving 5 or 6-axis operation, allow optimisation of probe and stylus performance for each application
  • Easily retrofitted to all Renishaw standard probe heads (M8 or autojoint) and compatible with existing TTP interfaces
  • Metrology performance equivalent to TP2-5W probe
  • Compatible with the full range of Renishaw probe heads and accessories

System components

Probe body (TP20 or TP20NI)

See below for more details.

TP20 stylus module

Seven variants allow for optimum performance for each application.

Module changing rack

For automated operation (MCR20).

Probe interface

TP20 can be used with PI 7-3 or PI 200-3.

TP20 probe body

  • TP20 guideHouses one half of the highly repeatable magnetic kinematic
    coupling
  • Contains a magnetic proximity switch to inhibit triggering of
    the probe during automatic module changing with MCR20

NOTE: If the probe is operated close to magnetised parts/clamping etc, the probe trigger may become inhibited. Countermeasures include the use of long styli, stylus extensions or body orientation to increase the distance to the magnetic source. Alternatively, use the TP20NI probe body.

TP20NI probe body

  • Probe body not affected by magnetic fields
  • Probe trigger must be inhibited through software during change cycles using the MCR20
