Tender description

Roundness instrument capable of preforming multi-step error separation for the measurement of high accuracy spheres and hemispheres along with routine measurement of cylindrical components. Lot 1: Supply of an instrument to replace the existing Talyrond 73UHPR (developed in a collaboration between NPL and Taylor Hobson) and Talyrond 295. The replacement instrument will be part of a national infrastructure to provide state of the art roundness measurements to industry via NPL’s measurement services. • Must be able to automatically measure spheres and hemispheres using multi-step error separation reporting both the component and spindle error • It must be possible to turn off any stored error map for the spindle. • Must have a reproducible spindle error at the order of nm level • Must have nm level resolution • Must enable export of raw data in ASCII format • Must run existing Ultra programs • The work will involve decommissioning the existing Talyrond 295 and replacing with a Talyrond 595 • Physical size of instrument is required to be similar to the existing Talyrond 295 • Support should be provided in the UK for regular service and for repairs. All of above must meet all NPL, UK and EU regulatory and health & safety requirements at all times. Taylor Hobson can provide a solution that meets all these requirements.
