Abstract: A milling tool includes a cutting insert, a holder, a fastener and a shim. The fastener forms a first channel cooperatively with the cutting insert. The first channel is configured to direct coolant towards a top side of the insert. In order to better prevent thermal fatigue of the cutting insert under milling conditions, the shim includes a second channel configured to direct coolant towards a clearance side of the cutting insert. A method of using a milling tool and a milling process are also provided.

Abstract: A double-sided tangential milling cutting insert for corner milling, contains: a first end surface, an opposed second end surface, two main side surfaces, two secondary side surfaces, and a through-hole penetrating the two main side surfaces. The first and second end surfaces each have two diagonally opposed raised corners and two diagonally opposed lowered corners. The cutting insert has a first symmetry plane and a reference plane dividing the cutting insert into two halves. First to fourth cutting edge sections each having a main cutting edge, a raised corner and a wiper edge are formed at intersections of the first and second end surfaces with the main side surfaces and secondary side surfaces. A transitional edge portion, connecting the wiper edge to an adjacent lowered corner, is formed along the secondary side surface.

Abstract: A milling cutting insert has a substantially triangular shape. The cutting insert contains a top side, an underside, and circumferential side surfaces extending between the top side and the underside. Cutting edges are formed at the transition of the circumferential side surfaces to the top side and/or the underside. On the circumferential side surfaces at least two discrete planar abutment surfaces are formed for positioning the cutting insert in a tool holder. The at least two discrete planar abutment surfaces are inclined with respect to each other at an outer angle of between 190° and 220° and the abutment surfaces are spaced from each other with respect to the circumferential direction of the cutting insert.

Abstract: A double-sided milling cutting insert has a first cutting edge disposed at an intersection of a top side and a side surface and a second cutting edge disposed at an intersection of a bottom side and the side surface. Each of the first and second cutting edges contains three cutting edge portions which are useable by indexing. The cutting edge portions each have a cutting corner, a main cutting edge adjacent to one side of the cutting corner, and a wiper edge adjacent to the other side of the cutting corner. The main cutting edge and the wiper edge are each inclined towards a reference plane with increasing distance from the cutting corner such that the first and second cutting edges have the largest distance to the reference plane in the regions of the cutting corners. The side surface has main clearance surfaces, secondary clearance surfaces, and curved corner surfaces.
