About motorised heads
Indexing heads
Motorised indexing heads are designed to position the probe at one of 720 positions, so probing can be carried out at many angles. The repeatability of the head allows to recall those positions without the need for requalification, saving operator time and applying the probe to the surface at the best angle for the most accurate result
Servo heads
Motorised servo type heads provide almost unlimited angular positioning and are ideally suited to horizontal arm CMMs.
