ABSTRACT:
The device comprises two rotary carrier-plates each fitted with a carriage which is equipped with a chuck for gripping one end of a crankshaft and which is adapted to move on a diametral guide of the carrier-plate. The plane of the axes of the crankpins is located in the plane of displacement of the axes of the jaws on each side of the axis of rotation of the carrier-plates at a distance equal to the radius "r" of rotational motion of the crankpins for the successive grinding of the outer crankpins and of the inner crankpins.
The invention is applicable to machines for grinding the crankpins of crankshafts having four crankpins located in the same plane.
