Roundness Introduction
Cylindricity measuring instrument is benchmark against precision rotary center and linear motion guide,the quantitative evaluation of the cylindricity is made by measuring the radius variation of actual contour of several cylindricity surface in different angle position to rotary center by displacement sensor in the guide. It is used to measure the error of contour shape of cylindricity workpiece (Roundness, cylindricity, planeness, straightness),position error ( concentricity, coaxiality, run-out and perpendicularity)
Measurement Capability:
Evaluation item: Cylindricity module: Radial full jump, concentricity, taper, radius Roundness module: Concentricity, radial single jump, wall thickness difference Straightness module: Parallelism, verticality Single section flatness module: Axial single jump, verticality and parallelism Multi-section flatness module: parallelism, Axial full jump, verticality Commutator module: Single contacts jump, Adjacent contacts jump, intermittent difference of contacts.
