ACR3 autochange rack
- Passive 4-port probe and extension bar changing system
- Enables rapid interchange of autojointed products without the need for probe requalification
- Fits onto modular rack system (MRS)
- Can be configured to provide 8 ports
- Provides covered storage and protection for probes and extension bars
- Uses motion of CMM to lock / unlock the autojoint
- No need for rack motors or electrical interface with CMM controller
- MRS / MRS2 rails available in 400 mm / 600 mm / 1000 mm (15.8 in / 23.6 in / 39.4 in) lengths to suit changer requirements
- Integration with metrology software is required
- Modular design enables individual port replacement in the event of excessive wear
Total swept volume along the MRS during a change cycle is:
|1 × ACR3||275 mm (10.83 in)|
|2 × ACR3s linked||460 mm (18.11 in)|
Compatible Renishaw products
Renishaw have a number of probe heads and probes that have either the male or female part of the autojoint fitted to them and are therefore compatible for use with the ACR3.
|A motorised indexing probe head with 720 repeatable positions suitable for all two wire and multiwired probes|
|An in-quill mounted version of the PH10M PLUS head|
|A fixed autojointed probe head suitable for all two wire and multiwired probes|
|High-accuracy scanning probe enabling the user to scan for form measurement and reverse engineering, rapid TTP for geometric measurements is also possible|
|Analogue contact scanning probe which is ideal for profile scanning and it features 300 mm stylus capability. Permits the CMM to gather large amounts of data very rapidly|
|High-accuracy strain gauge based touch-trigger probe|
|This is a probe suited to general purpose probing applications offering longer and heavier styli carrying capability|
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 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|
|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|
|A 13 mm diameter kinematic touch-trigger probe with adjustable stylus force|
|A 25 mm diameter kinematic touch-trigger probe of a robust design|
ACR3 can only be used in the horizonal orientation.
It is not possible to remove probes off the end of extension bars using ACR3.
Installation and user's guides
Installation & user's guide: ACR3
Mounted within the CMM’s working envelope, the ACR3 is combined with the modular rack system (MRS) to form an automatic change rack for probes and extension bars that incorporate the Renishaw autojoint.
User guide: SP25M, FCR25, ACR3 system
Renishaw’s innovative SP25M is the world’s most compact and versatile scanning probe system and is actually two sensors in one - enabling the user to scan for form measurement or reverse engineering and as a touch-trigger probe (TTP) for geometric size and position measurement.
Instruction leaflet: ACR1 / ACR3 / FCR25 port replacement
Renishaw racks allow fast repeatable exchanging of probes and styli without the need for manual intervention. This leaflet covers the replacement of ports for ACR1, ACR3 and FCR25 racks.
