QD12-10-C Radial Runout Of Table Axis

The Rotary Table on test is placed on a rigid and flat support surface with the Rotary axis in the vertical position. A precision sphere/hemi-sphere is placed and centred on the rotary axis at table top level. A high-resolution linear indicator is placed on the support surface close to the rotary table so that radial deviation measured at the apex of the sphere can be recorded over a minimum of two full revolutions of the table.
