Abstract

A cylinder grinding machine with devices for tracing and dimensional and surface checking has a front bench provided with rests for supporting the workpiece and a head and a counterhead for rotation and longitudinal restraint of the workpiece. A rear bench supports a carriage longitudinally movable on it parallel to the axis of the workpiece. On the carriage there is a wheelhead movable perpendicularly to the axis of the piece bearing the grinding tool. A third bench is rigid with the front bench and is located opposite the second bench. On the third bench a measuring carriage supporting more instruments tracing the dimensions and surface of the workpiece, operating both in contact and without contact with the workpiece, is movable. The carriage is provided with motorized devices which are autonomous and independent of the movements of the carriage supporting the wheelhead, it being possible for the measurement by such instruments to be carried out at the same time as machining and independently of it.
