Abstract
The invention relates to a machining tool (14) for machining materials by removing material, in particular for wood or wood-like materials, metals, plastics and/or composite materials. The machining tool is provided to be driven in rotation about an axis of rotation (1) and comprises at least one row (17, 18, 19) of individual cutters (2, 2″) arranged in the peripheral direction and having cutting edges (3, 3″) which at least partly overlap. The cutting edges (3, 3″) have a rake angle and are located at an axial angle (λ) in relation to the axis of rotation (1). The axial angle (λ) lies in a range from 55° to <90° inclusive. The rake angle is >55°.
Claims22
Machining tool (14) for machining materials by material removal, provided for rotary drive action about an axis of rotation (1), wherein the machining tool (14) has a base body (10) and, separate from the base body (10), at least one row (17, 18, 19), arranged in circumferential direction, of individual cutters (2, 2′, 2″) embodied as flat cutting plates (11) of an ultra-hard cutting material, wherein the flat cutting plates (11) each have a cutting edge (3, 3′, 3″) and the cutting edges (3, 3′, 3″) at least partially overlap each other, wherein the cutting edges (3, 3′, 3″) each have a wedge angle (β) and the cutting edges (3, 3′, 3″) each are positioned at an inclination angle lambda (λ1, λ1′, λ1″, λ2) relative to the axis of rotation (1), wherein the wedge angle (β) is measured in a plane perpendicular to the cutting edge (3, 3′, 3″), characterized in that the inclination angle lambda (λ1, λ1′, λ1″, λ2) is within a range of 55°, inclusive, to <90°, and in that the wedge angle (β) is >55°.
