Abstract
A tool for milling and drilling where the rotating tool has a bearing surface provided to cooperate with another bearing surface to take up radial cutting forces. The two surfaces are mutually separated by a fluid and are essentially axially non-slidable when the cutting tool is engaging the workpiece.
Claims20
A high-speed milling and drilling tool having a cutting part in the form of a cutting head, and a fastener means provided on the end of the tool remote from the cutting head, wherein at least a part of the tool forms a bearing surface in close proximity of the cutting head for the bearing that takes-up radially acting cutting forces, the bearing is in the form of a bearing surface provided to cooperate with the bearing surface of the tool, the two surfaces are mutually separated by a fluid and essentially axially non slidable in relation to each other when the tool is engaging the workpiece.
A tool for milling and drilling, said tool comprising:
- a cutting part in the form of a cutting head;
- a fastener provided on an end of the tool remote from said cutting head;
- and
- a bearing surface in close proximity of said cutting head and configured and arranged to transfer radially acting cutting forces to a bearing surface of a supportive bearing carried by a supporting part;
- wherein said bearing surface is separated from the supportive bearing by a fluid, and
- wherein said bearing surface is essentially axially non slidable in relation to the supportive bearing.
