Measuring up to nuclear requirements
Hexagon Manufacturing Intelligence has supplied an ultra-precision CMM to the Nuclear AMRC

The Nuclear AMRC has taken delivery of a Leitz PMM-C 12.10.7, an ultra-high precision co-ordinate measuring machine that offers sub-micron resolution on large parts and samples AMRC.

The Leitz CMM was chosen for its ability to inspect components and samples up to 1.2m in length and weighing up to 1,750kg. It is also equipped with a Precitec LR chromatic confocal probe for non-contact measurement of critical faces to nanometre resolutions, Profiler R sensor for automated tactile surface roughness measurement and an ultra-high precision rotary table to aid inspection and measurement of rotatives, blades, gears and splines.

“We chose the Leitz because of its stability and accuracy. Quality is critical in the civil nuclear industry and the machine’s sub-micron accuracy allows us to reach a deeper understanding of the manufacturing process,” explained Carl Hitchens, head of machining and metrology, Nuclear AMRC.

“We can then use this understanding to inform, improve and optimize the process, helping companies to demonstrate that parts made by new processes can meet the quality requirements of their customers,” he added.
On-machine inspection of large high value components is a major area of study for the Nuclear AMRC where a Hexagon Manufacturing Intelligence DEA DELTA, the largest gantry CMM available in any research centre, and Hexagon’s PC-DMIS NC machine tool metrology software are also in use.

“Multi-sensor systems are the future so the investment in the Leitz platform not only enables the centre to be an early adopter of next generation technologies, but also ensures the research team can validate and test systems“, added Carl Hitchens.
