Renishaw offers 5-axis touch-trigger probe

Renishaw's PH20 probe head, with two rotational axes, offers unique 'head touches' for rapid touch-trigger measurement, and fast infinite 5-axis positioning to guarantee optimal feature access.

The probe head also benefits CMM users through adaptive positioning to accommodate part misalignment, fast calibration routines, and an integral TP20 probe mount that optimises the working volume of the CMM, bringing 5-axis capability to smaller machines for the first time. By incorporating the industry standard TP20 touch-trigger probe, users of the PH20 probe head will immediately have access to a range of proven probe modules, providing a wide selection of trigger forces, directional sensing options and extensions to meet application requirements. The detachable modules provide crash protection and can be automatically changed using the MCR20 change rack. Companies with existing TP20 systems will be able to upgrade to PH20 and utilise their existing modules. The unit also offers benefits in probe calibration, which can be a long and laborious process. The PH20 offers dramatic time savings through a unique rapid 'inferred calibration' technique that determines head orientation and probe position in a single operation, allowing subsequent measurement at any head angle. Its compact design makes it suitable for new CMM purchases and as a retrofit to the vast majority of existing CMM touch-trigger installations. Read a related feature article here
