Mill, in particular for milling of bone, as well as a drum, provided with cutting members, applicable in the mill

摘要

A mill comprises a housing (3) and a drum (15), provided with cutting members (17), which is rotatably located inside the housing. The cutting members and the drum are made from one piece and the cutting members are formed by local thickenings of the wall of the drum. The cutting members have a cutting edge from which one point (41) protrudes in the circumferential direction of the drum, such that during operation the cutting members contact the material to be milled with this point first. The cutting members are located on the intersection of an imaginary spiraled line (47) around the drum and a number of imaginary oblique lines (49), which run at an angle with the axial direction of the drum. The cutting members are formed by machining the outer surface of a thick-walled drum, such that on the outer surface of that drum a spiral-shaped rim remains, which is removed at a number of places. Cutting edges with clearance surfaces are machined at the remaining parts of the rim.
