3.4 Universal datum sphere
The Renishaw universal datum sphere shown in figure 17 features quick and easy
alignment of its ball stem over a wide range of angles, allowing clearance for probe
qualification above, centrally and below the ball.
Each hard-wearing tungsten carbide sphere is supplied with a test certificate traceable
to UK (National Physical Laboratory) standards. For further information on the
sphere please refer to the universal datum sphere data sheet (Renishaw part number
H-1000-2250).
3.5 Autochange rack
Renishaw’s autochange racks shown in figures 18 and 19 are probe exchange systems
available for use with the PH10M and PH10MQ probe heads. Mounted within the
CMM’s working envelope, the autochange system facilitates fast, automatic probe
exchange without the need for requalification.
