The cylinder gauge SS-200ZC is a special-purpose tool for highly precise measurement of the flatness of machined surfaces, for the installation of workpieces on CNC, surface-grinding and milling machines plus the assembly and adjustment of tools and fixtures. Due to the very complex grinding process, the outer surfaces of the tool achieve a precision that far exceeds that of turned components. The areas relevant to the measurement are clearly differentiated from the surfaces of the grip at the top.
