The PHS1 probe head mounts onto the CMM quill via a kinematic mounting plate. This allows for easy exchange of heads and for interchangeability with other Renishaw motorised head systems.
The kinematic joint cam is locked in place using the 5 mm A/F hexagonal key supplied with each kit.
NOTE: The locking cam must be fully rotated when locked in position. The alignment mark on the cam is matched with the alignment mark on the housing when the cam is in its correct locked position.
Failure to ensure that the cam is fully locked could result in the cam unlocking during operation and the head becoming separated from the quill.
