Abstract:
1. Device for milling of materials, comprising: a milling cutter body that is connectable to a rotatable spindle or holder and defines a rotation axis, the milling cutter body being provided with at least one series of a plurality of tangentially spaced-apart cutting edges or a plurality of tangentially spaced-apart seats intended for milling inserts having at least one cutting edge, with the cutting edges of the series being arranged to machine a common surface in a workpiece, the cutting edges or seats of the series being arranged in such a way that, within the series, a first angle between a radius that intersects a first cutting edge and a radius that intersects another cutting edge, which is situated closest to the first cutting edge in a direction of rotation around the rotation axis, is smaller than a second angle between the radius that intersects the first cutting edge and a radius that intersects another cutting edge, which is situated closest to the first cutting edge in a direction opposite said direction of rotation, the first and second angle being in a radial plane perpendicular to the rotation axis, and within the first and second angle, respectively, there is an absence of any other cutting edge of the same series, wherein, within the series, a radial distance of the first cutting edge to the rotation axis is larger than a radial distance of the another cutting edge, which is situated closest to the first cutting edge in the direction opposite said direction of rotation, to the rotation axis, said radial distances to the rotation axis lying in said radial plane, and wherein, within the series, the radial distance of the first cutting edge to the rotation axis and the radial distance of the another cutting edge, which is situated closest to the first cutting edge in the direction opposite said direction of rotation, to the rotation axis are set in relation to the respective angles such that the first cutting edge and the another cutting edge, which is situated closest to the first cutting edge in the direction opposite said direction of rotation, cut chips from a work piece that have essentially the same chip thickness, said radial distances to the rotation axis lying in said radial plane.
