Surface roughness instrument-Mitutoyo SJ



It is used for measure roughness of cylinder surface (ex: roller), roughness of flat (ex: extrusion die landing area), even including stepped, straightness, waviness can be gauged. Measuring roughness of extrusion die, is also used for measure roughness of cylinder surface (ex: roller), even including stepped, straightness, waviness can be gauged.
