An optical inspection machine for the quality control of parts, in particular gaskets, comprises a rotary table on which parts to be inspected are placed and, above the rotary table, at least one viewing unit for inspecting one or more outer and/or inner surfaces of a part, a first part ejection station that is activatable to eject a part from the rotary table to a first external conveyor for compliant parts, and a second part ejection station that is activatable to eject a part from the rotary table to a second external conveyor for rejected parts. The viewing unit and part ejection stations are positioned on the rotary table with an angular distance between them, and are connected to a central mounting member that is coaxial to the axis of the rotary table and is movable vertically in relation to the rotary table.
