polishing disk via the boreholes 9 the rotating lambskin hood 5 functions as a unilaterally open centrifugal pump due to the scooping effect and gas friction as a result gas is constantly conveyed out of the working area and replaced by new cold gas surprisingly this effect leads to a permanent cooling of the polishing disk thus making it possible to initiate the polishing operation immediately without first cooling the work piece 10 the cooling effect is further promoted by positioning the polishing disk diagonally to the surface of the work piece 10 during polishing as a result the open centrifugal pump closely resembles a closed centrifugal pump with an intensified adhesion effect of the cold gas in the working area in this manner the surface to be polished and the entire polishing disk are constantly cooled in this process the cooling is completely sufficient and there is no need to interrupt the polishing operation in order to once again cool the work piece another advantage of the invention consists in soaking the polishing disk with polish it is no longer necessary to cover the surface to be polished with polish although it does not rule out this option when designing the processing tool attention should be paid to ensure that the outflow rate of the cold gas is not higher than the suction effect of the rotating polishing disk the stationary device according fig3 consists of a liquefied gas storage.
