ABSTRACT:
An apparatus for checking linear dimensions of mechanical parts comprises a bed, a longitudinal slide and two transverse slides arranged on the longitudinal slide and carrying relevant sensing elements adapted to touch the part to be checked. In order to obtain flexibility and quickness of operation, first and second reference rests for relevant parts are positioned on the bed and the transverse slides carry sensing elements having an arrangement substantially symmetrical with respect to a transverse symmetry plane. The apparatus is particularly suitable for checking parts after a first and, respectively, a second machining operation.
