Centrifuge for degreasing and washing objects, particularly industrially manufactured pieces having blind holes, comprises a housing provided with a tilting device for tilting the centrifuge into an inclined position and returning it into an upright position. A rotary centrifuge drum is located within the housing and is equipped with a drive ring connected to an additional drive arrangement having a friction wheel adapted to be pressed against the drive ring to reduce the rotational speed of the centrifuge drum.
