A measuring instrument for quantitatively evaluating the cylindricity of a cylinder by measuring the actual contour of the cylinder using the precise rotation centerline as the reference standard and the precise linear motion guide rail as the reference standard. It can be used to measure cylindrical shape errors (roundness, cylindricity, straightness, and flatness), position errors (coaxiality and verticality), etc.
The cylindrical Roundness Tester is mainly used to measure the roundness, cylindricity, straightness, concentricity, coaxiality, flatness, parallelism, perpendicularity, surface waviness, discontinuous surface, etc. of various regular and irregular circular workpieces. It can also perform spectrum analysis, wave height analysis, eccentricity, shaft bending analysis, and runout analysis on workpieces.
This device has excellent cost-effectiveness, full measurement capability, and is easy to learn and use.
