Abstract
A milling tool for a dental milling machine comprises a base body (11) with a rotation axis (12). A shank (15) for clamping the milling tool (10) is provided at a first end (13) of the base body (11). A cutting edge (16) is arranged at a second end (14) of the base body (11). A receiving section (17) is provided on the base body (11) between the shank (15) and the cutting edge (16). A blower wheel (20) is arranged on the receiving section (17) of the base body (11). The blower wheel (20) is formed such that, when the milling tool (10) is driven in a direction of rotation (19) provided for chip removal, an air flow (25) is generated by the blower wheel (20) in the direction from the blower wheel (20) toward the cutting edge (16) of the milling tool (10).
Claims15
A milling tool (10) for a dental milling machine, the milling tool (10) comprising:
- a one-piece base body (11) extending along a rotation axis (12) from a first end (13) to a second end (14), the base body (11) including a shank (15) for clamping the base body (11) at the first end (13), a cutting edge (16) formed on the base body (11) at the second end (14), and a receiving section (17) between the shank (15) and the cutting edge (16);
- and
- a blower wheel (20) arranged on the receiving section (17) of the base body (11), the blower wheel (20) being designed such that, when the milling tool (10) is driven in a direction of rotation (19) provided for chip removal, an air flow (25) is generated by the blower wheel (20) in a direction from the blower wheel (20) toward the cutting edge (16) of the milling tool (10),
- wherein the blower wheel (20) comprises a hub (22) and a pot-shaped retaining body (23) adjacent to the hub (22),
- wherein the hub (22) is press-fitted on the receiving section (17), and
- wherein blades (21) of the blower wheel (20) are attached to an outer surface of a circumferential wall (27) of the pot-shaped retaining body (23).
