Abstract
A divided milling cutter comprises a first cutter half and a second cutter half which are adjustable in relation to each other with respect to their mutual distance and are both connected to a first, common, hydraulic sleeve which has an internal, annular pressure chamber and is threadable on to and securable to a cutter spindle or the like. To make possible a continous or step-less variation of the distance between the cutter halves in a simple way even when they are mounted on the cutter spindle said second cutter half is fastened to a second sleeve which is in threaded engagement with a third, threaded sleeve having a substantially annular flange which abuts an end of, or shoulder on, the first sleeve. In working position the sleeves and the cutter halves are retained on the cutter spindle by pressurizing the hydraulic sleeve for pressing the inner wall of its pressure chamber against the cutter spindle and the outer wall of said chamber against said second sleeve and the inner circumference of said cutter halves.
