Abstract:
A milling tool comprising a supporting body rotatable about a central axis, the supporting body including an outer endless peripheral face forming a plurality of first serrated surfaces arranged circumferentially about the axis; a plurality of cassettes each having a second serrated surface, each cassette having its respective second serrated surface meshed with a respective first serrated surface; each cassette carrying a cutting insert having at least one cutting edge; each of the first and second serrated surfaces comprising straight parallel ridges alternating with straight parallel grooves; the ridges and grooves extending parallel to the axis; each of the first serrated surfaces forming an angle in the range of 65-90.degree. relative to a line extending radially from the axis of the supporting body and intersecting a center of the first serrated surface as viewed in a direction parallel to the axis; each of the cassettes including a through-hole aligned with a hole extending through the first serrated surface; and a clamping screw extending through the through-hole and disposed in the hole for securing the cassette to the supporting body, there being sufficient play between the clamping screw and the through-hole to enable the cassette to be adjusted relative to the supporting body in a direction parallel to the axis when the clamping screw is in a loosened state.
