Improved advancement device, which is applicable to machine tools and is constituted by the tandem coupling of a pair of double-acting cylinders, one of which is hydraulically driven and the other pneumatically operated, the corresponding pistons being fixed to a contiguous rod, essentially is characterized in that the displacement or stroke of the pistons 1 and 2 is graduated by means of a rod 12 threaded to a projection 14 normal to the axis or common rod 15 of said pistons, whose rod 12 is disposed parallel to the rod itself 15, so that the free end of said rod 12 pushes in one phase of its reciprocating movement and overcoming the resistance of an expansion spring to a valve 13 that closes the liquid communication conduit between the two chambers of the hydraulic cylinder.
