Datum sphere kit Ø19 mm ball

Datum sphere kit Ø19 mm ball
The Renishaw universal datum sphere enhances the performance of manual and fully automated CMMs. It allows for quick and easy adjustment to set ball stem over a wide range of probe datuming angles. This enables datuming above, centrally and below the ball. Each datum sphere is supplied with its own certificate, giving ball diameter and roundness. All sphere measurements are performed on equipment traceable to UK (NPL) standards.
Please note that datum ball fixing studs are not included in the kit.
