ABSTRACT:
Apparatus for checking diameters and other geometrical features of workpieces having internal and or external surfaces of rotation including a base and a plate carried by the base and having a plurality of slots for supporting and adjusting the position of measuring heads. The measuring heads include feelers adapted to contact the workpiece to be checked. A plurality of measuring heads can be clamped in each slot. The slots are parallel to one another and their axes are arranged side by side in a direction perpendicular to a geometrical plane in which the feelers of the measuring heads lie. The base supports a nosepiece providing a mechanical reference for the workpiece to be checked.
