ACR2 autochange rack
The ACR2 autochange system is an arm-changing system for the PHS1 servo positioning head system. It allows probe extensions or probe adapter arms to be exchanged to suit the probing task required.
Arms are locked or unlocked from the head by motion of the machine itself. The head engages a rack port and the machine drives the port up to unlock an arm or down to lock it in position.
No power connections or signal connectors are necessary to the rack, making installation very simple.
The ACR2 is supplied as pairs of rack ports which are mounted onto a suitable fixture supplied by the OEM. The system is modular and any number of port pairs can be used anywhere on the CMM.
