  • Patent number: 11745296
    Abstract: A milling tool having an operating area that is rotatable about an operating axis of rotation for milling a workpiece. The operating area has at least one milling edge extending transversely to the circumferential direction (U) of an operating axis of rotation. At least one of the at least one milling edge includes at least one milling edge portion in which a milling edge profile (P), which is defined by the radial distance (F) between the milling edge and the operating axis of rotation along the milling edge, has a non linear progression. The milling edge in the milling edge portion has a chip space, which extends radially inward toward the operating axis of rotation in relation to the milling edge. The chip space has a chip space base that follows the milling edge profile (P) at least in portions in the milling edge portion with the non-linear milling edge profile (P).

  • Patent number: 10646968
    Abstract: A finishing tool of an end milling cutter can comprise: a chip-removing milling edge, which extends continuously with respect to the tool axis (A) over an axial length (L) on a circumferential surface (U), which is rotationally symmetrical about the tool axis, and removes workpiece chips from the workpiece surface at a radial chip-removing engagement depth (T to Tmax), and at least one non-cutting pressing ridge, which extends continuously axially with respect to the tool axis (A) over an axial length (L) on a circumferential surface which is rotationally symmetrical about the tool axis, is arranged following an associated milling edge by a pitch angle, and presses over its entire axial length (L), during the milling movement, at a radial non-cutting engagement depth (T or RS?RD) with respect to the tool axis into the workpiece surface machined by the associated milling edge, and smooths said workpiece surface.
