Autojoint system

The Renishaw autojoint is a highly repeatable joint which is fitted to certain probe heads, eliminating the need to re-qualify the probe after a probe change.

The autochange system requires a probe head fitted with an autojoint.  Renishaw have a number of probe heads and probes that have either the male or female part of the autojoint fitted to them.  Listed below is a brief description of each.  For additional information, please refer to the relevant product documentation.

Heads

PH10M PLUS - A motorised indexing probe head with 720 repeatable positions suitable for all two wire and multiwired probes.

PH10MQ PLUS - This is an in-quill mounted version of the PH10M PLUS head.

PH6M - A fixed autojointed probe head suitable for all two wire and multiwired probes.

Probes

SP25M - High accuracy scanning probe enabling the user to scan for form measurement and reverse engineering, rapid TTP for geometric measurements is also possible.

SP600M - Analogue contact scanning probe which is ideal for profile scanning and it features 300 mm stylus capability.  Enables the CMM to gather large amounts of data very rapidly.

TP7M - High accuracy strain gauge based touch-trigger probe.

TP6A - This is a probe suited to general purpose probing applications offering longer and heavier styli carrying capability.

OTP6M - An optical trigger probe that uses a visible laser spot to provide a non-contact inspection solution for CMMs.

Using the Renishaw range of probe adaptor bars (PAA), the complete range of Renishaw M8 probes can be used in conjunction with the autochange system; a brief description of some of these probes is given below:

TP20 - A 13 mm diameter kinematic touch-trigger probe consisting of a two piece design that provides the facility to repeatedly change probe modules without the need for re-qualification.

TP200 - A 13 mm diameter strain gauge based touch-trigger probe consisting of a two piece design that provides the facility to repeatedly change stylus modules without the need for re-qualification.

TP2 - A 13 mm diameter kinematic touch-trigger probe with adjustable stylus force.

TP6 - A 25 mm diameter kinematic touch-trigger probe of a robust design.

NOTE: If a probe extension bar is manually locked (using an S10 autojoint key), it is advisable to lock it fully to the cam end stop then back the screwdriver slot off by approximately 5. If this is not done, it is unlikely that the probe will dock into the autochange rack.
