  • Page 7 MSR1 module storage rack (manual operation) The Renishaw TP20 touch-trigger probe is a 5-way or 6-way kinematic probe with the facility to change stylus configurations without the need for re-qualification. A direct replacement for the industry-proven Renishaw TP2, the TP20 can be easily retrofitted into existing TP2 applications to bring this additional facility to both manual and DCC co-ordinate measuring machines (CMMs).
  • Page 8 One or two TP20 probe modules (see TP20 probe kits for available combinations) Probe and stylus tools TP20 probe body The probe body incorporates a standard Renishaw M8 × 1.25 mm screw connector mount and is designed to house the mating half of the probe module's kinematic coupling. TP20 inhibit probe body This contains the magnetic proximity switch necessary to inhibit triggering of the probe during automatic changing of the probe modules.

  • Page 18 TP20 user's guide www.renishaw.com Fitting a probe module and stylus onto a probe body 1. Visually examine the mating faces of both the probe module and the probe head for cleanliness. Where necessary, clean the mating surfaces using the CK200 cleaning kit (supplied).
  • Page 19 Using the 1.5 mm hexagonal key supplied, fully hand-tighten the M3 cone point grubscrew (0.5 Nm - 1 Nm) to lock the MCR20 in position. NOTES: Whilst the TP20 system does not require that the MCR20 is aligned with the CMM axes, ease of programming or software constraints may make alignment with the CMM axes desirable.
  • Page 20 Datuming MCR20 NOTES: Renishaw recommends that datuming of the MCR20 is performed using the Renishaw PS2R stylus supplied. If a different stylus is to be used, the length (L) must be either 20 mm or 30 mm and the appropriate ball radius (R) must be used to calculate offsets.
