The Mitutoyo roundness measuring instruments deliver world-class rotational accuracy and industry-leading precision for roundness and cylindricity measurement. All models are equipped with a high-accuracy, easy-to-use rotary turntable on an air bearing, designed with stability and wear resistance in mind.
Combining Precision and Ease of Use
To reduce setup for measuring roundness and cylindricity, select Mitutoyo systems come standard with A.A.T. (automatic adjustment table) positioning and leveling function, freeing the operator from centering and leveling workpieces. Mitutoyo’s linear scales are incorporated into the system’s X-axis positioning sensor, directly sensing the displacement of the drive unit to achieve highly accurate positioning and repeat measurements.
