Claim Text:
1. A milling tool for precision machining of crankshafts or camshafts using three different types of cutting inserts arranged along an external periphery of the milling tool, wherein the first type of cutting insert is coated with TiAIN or TiCrN and includes a generally cuboidal base body made of a coated hard material with two machining surfaces and a cutting edge along a transition from each machining surface to two opposing side surfaces, and a fastening opening extending through the two opposing side surfaces such that the first type of cutting insert is mounted on a surface that is substantially perpendicular to an axis of rotation of the milling tool, and wherein the second type of cutting insert is coated with TiAIN or TiCrN and includes a generally cuboidal base body made of a coated hard material with two machining surfaces and a cutting edge along a transition from each machining surface to the two opposing side surfaces, and a fastening opening extending through two opposing side surfaces such that the second type of cutting insert is mounted on a surface that is substantially perpendicular to the axis of rotation of the milling tool, and wherein one of the two opposing side surfaces is formed with two partial surfaces inclined at a non-zero angle with respect to each other separated by a transition edge passing through a center of the fastening opening, and wherein the third type of cutting insert is coated with cubic boron nitride (CBN) or polycrystalline diamond (PCD), and wherein the third type of cutting insert is mounted on a surface that is substantially perpendicular to the axis of rotation of the milling tool, and wherein the cutting inserts are secured to the milling tool by a fastening screw, and wherein a central axis of the fastening screw is substantially parallel to the axis of rotation of the milling tool.
