A cutting insert for a milling tool is provided. A longitudinal plane extends halfway between a first pair of opposing side surfaces of the cutting insert. A first axial relief face adjacent to the a auxiliary cutting edge and a first axial abutment face form part of a first surface grouping on a first side of the longitudinal plane, and a second axial relief face adjacent to a second auxiliary cutting edge and a second axial abutment face form part of a second surface grouping on a second side of the longitudinal plane. The first surface grouping and the second surface grouping meet in a partitioning line, wherein the partitioning line extends in the longitudinal plane, and wherein the partitioning line extends from the first side to the second side.

Cutting insert and milling tool

A cutting insert for a milling tool is provided. A median plane extends through the cutting insert. A longitudinal plane extends perpendicularly to the median plane. In a view towards a first side surface, a first axial relief face and a first axial abutment face form part of a first surface grouping on a first side of the longitudinal plane. In a view towards a second side surface, a second axial relief face and a second axial abutment face form part of a second surface grouping on the first side of the longitudinal plane. The first axial abutment face forms a substantially flat surface. The first axial abutment face extends perpendicularly to the median plane. The second axial abutment face forms a substantially flat surface. The second axial abutment face extends perpendicularly to the median plane.

A cutting insert includes a first surface having a first rake surface, a second surface having a second rake surface, a central axis of the insert extending between the first and second surfaces, four side surfaces extending between the first surface and the second surface, and four cutting edges. Each cutting edge has a first cutting edge component and a second cutting edge component and being associated with a respective one of the first and second surfaces and with two respective ones of the side surfaces. The first rake surface is identical to the second rake surface and the first rake surface and the second rake surface are oriented at a 90&#xb0; angle to each other about the central axis of the insert.

Indexable, double-sided cutting insert and cutting tool including such an insert

In a method for producing a surface that is intended to form part of a coupling for use in chip removing machining, the surface includes a number of groove sets to allow locking by shape against another surface provided with grooves. Each groove set has a main direction, and the main directions of adjacently situated groove sets intersect. The number of groove sets are at least three, each groove set is produced in a separate cutting operation, and an equally large part of the surface is machined during each cutting operation. A surface that is intended to form part of a coupling for use in chip removing machining is also disclosed.

Method for producing a surface, and a surface

A cutting insert for milling comprises two major sides, two minor sides, and upper and lower sides. At least one pair of cutting edges is formed at the transition of the upper side with a major side and a minor side of the cutting insert. The upper side constitutes a chip surface, and the major and minor sides constitute clearance surfaces. Each pair of cutting edges comprises a major cutting edge extending along the major side, and a minor cutting edge extending along the minor side. The major and minor cutting edges intersect in the area of a cutting corner. The cutting corner is provided inside an imaginary extension line of a major part of the minor side. The major cutting edge slopes such that it forms an acute angle with the lower side. Each pair of cutting edges joins a first clearance surface protruding relative to a plane containing a major portion of the minor and major sides. Recesses are formed in the major sides.

Tool and cutting insert for milling

A milling cutter includes a holder and cutting inserts held in the holder by fasteners. Each cutting insert has an octagonal basic shape and includes eight cutting edges created by the intersection between an upper face and an edge face of the insert. The fasteners bear frictionally against the upper faces of respective inserts. The upper face comprises a number of safety stop projections. In the event that the insert slips relative to the fastener during a milling operation, one of the safety stop projections abuts the fastener to prevent accidental dislodgement of the insert.
