Abstract
The disclosure relates to a milling tool for wood or wood-like materials, as well as a method for producing such a milling tool. A longitudinal direction, a radial direction and a rotational direction are specified by an axis of rotation of the milling tool. The milling tool includes a base body as well as at least one blade which adjoins a rake face pointing forward in the rotational direction and a flank face pointing outward in the radial direction. The blade and the rake face run in a curved manner in the longitudinal direction. The curved blade and the curved rake face are formed on a cutting plate formed separately from the base body. The cutting plate is fastened to and in particular soldered on with its flat inner surface on a flat support surface of the base body.
Claims13
A milling tool for the machining of wood or wood-like materials, wherein the milling tool is configured to rotate about an axis of rotation, wherein a longitudinal direction, a radial direction, and a rotational direction are specified by the axis of rotation, the milling tool comprising:
- a base body defining a circumferential side;
- a blade arranged on said circumferential side of said base body;
- said blade adjoining a rake face oriented forward in the rotational direction and a flank face oriented outward in the radial direction;
- said blade and said rake face running in a curved manner in the longitudinal direction;
- said blade and said rake face being formed on a cutting plate formed separately from said base body;
- said cutting plate having a flat inner surface opposite said flank face, wherein said flat inner surface faces radially inward toward said base body;
- said base body defining a flat support surface which corresponds to the flat inner surface;
- said cutting plate being fastened on said flat support surface of the base body via said flat inner surface;
- wherein said cutting plate is formed from a composite material with a carrier layer and with a hard layer;
- said cutting plate is fastened to said base body with said carrier layer directed inward in the radial direction;
- and,
- said hard layer lies outside said carrier layer in the radial direction and forms said flank face.
