A milling and boring tool with a tool shaft which comprises a center axis, at least one geometrically defined rough cutter and at least one geometrically defined finishing cutter, and the at least one rough cutter and the at least one finishing cutter respectively comprise a chip groove. The milling and boring tool is characterized in that the chip groove of the at least one finish machining cutter has an opposite twist than the chip groove of the at least one rough cutter.

A milling tool is disclosed. The milling tool may include an elongated body having a longitudinal axis and a plurality of cutting inserts. The cutting inserts may each have a cutting edge and a cutting radius and be coupled to the body and spaced along the longitudinal axis. One or more of the plurality of cutting inserts may be adjustable (e.g., mechanically adjustable) between first and second cutting radii. A difference between the first and second cutting radii may be at least 10 m. The milling tool may include cutting inserts having a plurality of different cutting radii. The milling tool may be configured to have a length that spans an entire height of an engine bore. The cutting inserts having different radii may compensate for dimensional errors in an engine bore diameter that occur when milling a deep pocket.

A method for milling a planar surface, during which a milling cutter, an axis of rotation of which is perpendicular to a surface to be machined, is moved in a direction parallel to the plane of the surface, to machine the surface in a single machining operation, over a predetermined layer of material, using a single milling head, and the milling cutter, in a same axial position relative to the surface to be machined, simultaneously carries out rough working, at least one intermediate finishing operation, and a finishing operation over a same layer of material.

A cutting tool assembly includes: a cutter body extending perpendicularly from a bottom surface and including a cylindrical portion with a rotational axis; insert pockets disposed and formed concavely in the bottom surface and the cylindrical portion to be spaced apart from each other along a circumferential direction; fixed cutting inserts mounted within the insert pockets and disposed at the outermost portion of the cutter body in a radial direction; and stepped cutting inserts mounted within the insert pockets, the stepped cutting insert being disposed between two adjacent fixed cutting inserts. The fixed cutting insert is disposed to have an identical length from the rotational axis and an identical length from the bottom surface. At least one stepped cutting insert is disposed to have a different length from the rotational axis and a different length from the bottom surface compared to the remaining stepped cutting inserts.

The invention relates to a milling tool having a plurality of first blades and at least one second blade, which are arranged on the milling tool in a staggered manner in the circumferential direction of the milling tool, wherein the plurality of first blades are arranged in the axial direction of the milling too at a nominal position, wherein the plurality of first blades comprises a compensation group having at least one compensation blade and at least one non-compensation blade, wherein the at least one non-compensation blade is assigned a nominal cutting circle, wherein the at least one compensation blade is assigned a compensation cutting circle, wherein the nominal cutting circle and the compensation cutting circle are different, wherein the at least one second blade is offset forward in the axial direction of the milling tool by a forward offset with respect to the nominal position in the direction of a machining front end, wherein the at least one second blade is assigned a surface machining cutting circle, wherein the surface machining cutting circle is smaller than the nominal cutting circle and than the compensation cutting circle, wherein the at least one second blade leads the plurality of first blades in the circumferential direction.

A tooling assembly for a machine having an automatic tool changing system includes a tool body disposed about a rotational axis and defining an internal passage operable to flow a fluid therein. The internal passage includes an inlet, stem channel, first and second curved channels, and first and second transition portions. The inlet is configured to receive the fluid from the machine. First and second outlets are open through an exterior of the tool body. The stem channel is in fluid communication with the inlet and ends at a beginning of the first and second transition portions. The first curved channel extends from the first transition portion to the first outlet. The second curved channel extends from the second transition portion to the second outlet.
