The high rotational accuracy of the unit’s turntable (radial [0.02+6H/10000] µm, axial [0.02+6X/10000] µm) enables measurement of flatness in addition to roundness/cylindricity. The system features a DAT (Digital Adjustment Table) mechanism that makes workpiece centering and leveling simple and fast, since measurement functions including arc measurement are automatic. DAT table setup can even be incorporated into the part program to eliminate human error in centering and leveling. A high-precision, power-driven Z-Axis column enables evaluation of straightness as well as cylindricity. A detector is included to prevent damaging collisions in the Z-Axis.
