CMM Probe Heads
Motorized servo type heads provide almost unlimited angular positioning adn are ideally suited to horizontal arm CMMs.
Renishaw PH10 Probe Heads
Motorized indexing heads allow flexible and repeatable probe orientation. The range comprises the PH10 models each of which can carry a range of probes, extensions and can be orientated in 720 repeatable positions, giving access to the most difficult to reach workpiece features.In May 2009, Renishaw introduced a series of design enhancements for its range of PH10 motorized heads, resulting in a 20% improvement in repeatability and increased long term stability.
All three variants fo the new PH10 heads are not supplied with a revised repeatability specification, down from 0.5microns to just 0.4microns. (at a specified distance of 62mm), giving users improved positioning at the stylus tip. The new specification heads are physically differentiated by a new "aqua blast" finish which gives a more modern, matt black finished appearance.
Renishaw PH20 Probe Head
Renishaw's newest innovation, the PH20 probe head transforms coordinate measuring machines performance. For the first time, 5-axis technology developed for the multi-award winning REVO measurement system is available for touch-trigger application on all size CMMs.
PH20 Increases Throughput
The Renishaw PH20's unique "Head-Touches" allow measurement points to be taken by moving only the head rather than the CMM structure. Using only the rapid rotary motion of the head, points can be taken faster, and with improved accuracy and repeatability.
Easy Access To Features At Any Angle
PH20's infinite positioning capability guarantees optimal feature access, minimizing stylus changes.
5-axis simultaneous motion allows larger parts to be measured on the CMM by minimizing the space required around the part for head rotation.
PH20 automatically aligns itself with the part coordinate system, avoiding stylus collisions and the requirement for accurate fixtures.

Renishaw Renscan5 REVO
Revo is a dynamic new measuring head and probe system from Renishaw. A revolutionary new product designed to maximize CMM throughput while maintaining high system accuracy.
Renscan5 5 enables unrivalled performance and speed. Unlike conventional scanning methods 5-axis scanning uses synchronized motion of CMM and head axes to minimize the machine's dynamic errors at ultra-high scanning speeds. Up to 500mm/s is possible without any loss in accuracy.
From 55 minutes to 5 minutes
900% throughput improvement scanning head gasket faces and five sections in each of the eight cylinder bores typically takes 50-55 minutes. The Renscan5 REVO systems completes the job in 5 minutes. In conventional measurement methods the CMM performs all the movements necessary to aquire the surface data. Acceleration induces inertial deflections in the machine structure, which turn induce measurement errors.
Renscan5 Explained
Metrology system manufacturers have devoted years to develop techniques that reduce those dynamic errors, but there is an upper speed limit imposed by the machine and servo system stiffness, beyond which measurement cannot be taken with reliability.
Renscan5 breaks through that limit by using an articulating head that moves in two rotary axes as it measures. This allows the CMM to do what is it best designed to do - move at constant velocity in a single vector while measuring. As the head is much lighter and more dynamic than the CMM, with a significantly better bandwidth, it is able to quickly follow changes in the part geometry without introducing harmful dynamic errors which results in much faster surface speeds and hence shorter measurement cycles.
5-axis scanning technology allows the user to achieve unprecedented levels of throughput while maintaining current levels of metrology.
