Orientation adjustment device for surface finish measuring instrument has height controller that sets vertical movement of surface finish measuring instrument in parallel to body that holds instrument

摘要

A sensor (11) detects surface finish of workpiece. A drive unit (12) moves sensor in baseline (12A) direction. A surface finish measuring instrument (1) is held by a body (20). An orientation controller (30) adjusts the orientation of the body by setting the height of a foot that rests on the workpiece. A height controller (40) sets the vertical movement of the measuring instrument in parallel to the body.
