The universal system component for use with any multicoordinate measuring machine, regardless of model or manufacturer, is this fully motorized, extremely accurate probe head. Extension bars up to 300 mm in length can be used with it.
A kinematic joint (HH-A-T7.5 and HH-AS-T7.5) or an M8 threaded connection (HH-A-M7.5 and HH-AS-M7.5) can be used to connect sensors to the Probe Head.
The Probe Heads may achieve 720 distinct locations and index in 7.5° increments.
High rotational torque and high speed operation are features of the probe heads. Without requiring requalification, sensors can be replaced manually or automatically (using the HR-R probe changer).
The probe head can be mounted to the machine in two different ways.
Features & Benefits
- 720 places that can be repeated in 7.5° increments
- Operation at high speed: 90° in 2 seconds
- High Torque: 0.6 Nm
- 300mm is the maximum extension length.
- HH-A-M7.5
- All M8 thread extensions and probes are compatible.Fully Multiwired TKJ connector
- HH-A-T7.5
When using the HR-R rack, the probe changes quickly and automatically.
