[0002] A dial indicator is a length measuring instrument that converts general linear displacement (linear motion) into the rotational motion of a pointer through gears or levers and then reads the measurement on a scale. Dial indicators are widely used indicating measuring tools in precision measurement, mainly used to check the shape and position errors of workpieces (such as roundness, flatness, perpendicularity, circular runout, etc.), and are also commonly used for precise alignment of workpieces. Existing grinding disk flatness measuring instruments generally set multiple dial indicators on the main frame to measure flatness. The measured flatness is actually the height difference at the location where the dial indicator is located.
