Roundness Tester

The instrument is suitable for the measurement of the surface Roundness, Waviness, Coaxiality, Perpendicularity, Parallelism, Flatness and other parameters of various regular and irregular rotary workpieces (roundness error can be evaluated by four methods) and can give the eccentricity and phase of the part. It can also be used for the measurement of parameters such as roundness, beating amount, monolithic beating, and adjacent sheet beating of various motor rectifiers on discontinuous surfaces, and can give the eccentricity and phase of the parts.
