3 The table provides high rotational accuracy radial (0.02+6H/10000) µm; axial (0.02+6X/10000) µm, enabling the system to measure flatness and other characteristics, in addition to roundness/cylindricity, at a level that suits any application. The RA-1600 has also inherited the D.A.T. (Digital Adjustment Table) mechanism used in top-end devices to make workpiece centering and leveling quick and easy. The operator simply has to manipulate the digital micrometer heads of the turntable to match the adjustment values displayed on the monitor. Even notched workpieces can be measured accurately. Centering and leveling operations carried out by using the D.A.T.* can also be incorporated into the measurement procedure (part program). This prevents human errors when performing centering and leveling, and helps standardize measurement operations executed by the part program. *Centering and leveling is a manual process guided by the display.
