RPI celebrates 80 years with launch of TruMotion and QuadProfile horizontal axis

RPI Ltd is celebrating 80 years of leading the world in rotary measurement at Control 2020.

To mark its anniversary, RPI – the world’s leading specialist developer and manufacturer of precision positioning devices for high accuracy rotary and angular inspection systems – will be launching TruMotion, a manual spin rotary table designed to inspect circular components such as gauges, bearings, aero engine components and optical assemblies in a shop floor environment whilst maintaining world class accuracies more commonly seen in the standards laboratory.The QuadProfile horizontal axis will also be debuting at this year’s show.  Designed as an additional rotary axis for high precision co-ordinate measurement machines (CMMs) it delivers high speed measurement of smaller parts such as inner engine blades and gears.

Jim Palmer, RPI’s sales manager, said: “We’re delighted to be celebrating our eightieth birthday at Control.  As a German-owned company, we couldn’t have picked a more perfect venue for the party. We grew out of a number of acquisitions including Eimeldingen, which was based in Baden-WüRttemberg .

“The world has changed a lot since the 1940s but our passion to design and manufacture exceedingly dependable, low maintenance products, with a service life measured in decades, not just years, remains as true today as it was eighty years ago.  We’re very excited to launch our latest products, TruMotion and QuadProfile horizontal axis, at this year’s show and we hope they’ll create a real buzz!”

RPI will also use the show to demonstrate GeoInspec – a manual spin air bearing rotary table for optimal circular geometry inspection.  Automated data collection hardware used with both TruMotion and GeoInspec will also be on display.

Other products on show include: QuadSlimLine rotary table for use with CMMs for inspecting component parts such as gas turbine discs and fan blades. Specifically designed as a fourth axis, they are accurate to 2 arcs second. RPI has been supplying the CMM market since 1977 and can boast more than 750 successful installations worldwide.

Meanwhile, visitors to RPI’s stand can also see LabStandard and LabStandardAIR High rotary tables. Typically used for calibration of inclination sensors and navigation systems such as gyroscopes enabling both horizontal and vertical application, they offer sub arc second angular accuracy and precision geometry for inspection and calibration labs, with the versatility of both single and dual axis making them accurate to +/- 0.5 arcs seconds. This is equivalent to hitting a golf ball at a hole more than 22km away and scoring a hole in one every time!

The LabStandardAIR has been designed as a contact free system and eliminates features which may detract from achieving the optimum rotational performance. The rotating elements are supported on super high precision, air lubricated, hydrostatic bearings and are not subject to disturbances associated with gear drives.

RPI grew out of acquisitions from Optical Measuring Tools, Airmatic, Horstmann and Eimeldingen.   It is now one of the world’s largest designers and manufacturers of solution driven, highly accurate inspection systems and services that measure circular geometry and angular positioning.  Using its 80 years of rotary expertise, RPI supplies progressive engineering industries, including the aerospace, gas turbine and dimensional metrology sectors, with exceedingly dependable, low maintenance products with a service life measured in decades, not just years.
