Following a series of design enhancements, Renishaw's industry-standard family of PH10 motorised indexing
heads for co-ordinate measuring machines (CMMs) now have a 20% improvement in
repeatability and increased long-term stability.
Combined with an optional extended 2-year warranty, the new PH10 heads offer
CMM users a new standard of indexing head performance, providing reliable
precision in even the most demanding measurement applications.
All three variants of the new PH10 heads are now supplied with a revised
repeatability specification, down from 0.5µm (2s) to just 0.4µm (2s) (specified
at a distance of 62 mm), giving users improved positioning at the stylus tip.
Flexible and repeatable CMM probe re-orientation
The improved positioning
is especially important in long reach applications such as those using the SP25M
scanning probe. This has been achieved by improving the mechanical stiffness of
the head design, and through enhancements to manufacturing processes.
Additionally, the use of the latest surface mount electronics technology gives
further improvements to head robustness and reliability.
Renishaw's PH10 motorised indexing heads allow flexible and repeatable probe
re-orientation during CMM measurement routines. The range comprises three
models, each of which can carry a range of probes and extensions, and can be
orientated in 720 repeatable positions, giving access to the most
difficult-to-reach workpiece features. The PH10T supports M8 threaded probes
such as TP20, whilst the PH10M uses the Renishaw 'autojoint' system to carry
complex multiwired probes such as SP600M and SP25M. For machines and
applications where a direct quill mount is required, the PH10MQ offers all the
functionality of the PH10M. All the range supports extension bars up to 300 mm.
The new improvements combine to provide increased long-term motorised head
stability, giving CMM users the option to extend the time interval between
calibrations. A further differential is also provided by an all new 'aqua blast'
finish which gives the new PH10 heads a modern, matt black appearance, and
clearly identifies the higher specification units.
New CMM heads available through attractive upgrade options
upgrade options for the new higher specification PH10 motorised indexing heads
are being offered to existing PH10 users, who can trade in their old head via
any Renishaw service centre or authorised supplier. Additionally, users
returning an existing head for repair can now take advantage of a special
variant of Renishaw's unique low cost 'repair by exchange' (RBE) service, where
a new specification PH10 head will be supplied, ensuring minimal down time. In
both circumstances it is a quick and simple operation to install the new head,
with the CMM up and running after a standard head calibration routine, without
the need for specialist commissioning or changes to part programs.
For CMM users who do not currently use a PH10 motorised indexing head, there
are also attractive incentives to purchase a new PH10 head through approved
suppliers who are participating in Renishaw's unique 'Changers' promotion. A
free stylus change rack can be claimed with every new head purchased, subject to
each supplier's terms and conditions. All new PH10 heads also come with a
standard 12 month warranty, with an additional 24 months warranty cover
available at very competitive rates, giving extra piece of mind for this
important measurement equipment.
