This is to measure the straightness of lead edge groove (spiral) of VTR cylinder.
It is a combination of a surface roughness measuring function to the roundness measuring instrument. By rotating the table which made of porous static air pressure bearing, and controlled by roughness amplifier, circumferential roughness on the cylindrical workpiece is possible to measure.
The unit which is measuring groove width on the side of workpiece, and bus lines of round objects, or others are available.
