Abstract: PROBLEM TO BE SOLVED: To safely operate a milling cutter tool provided with an inserted cutting blade possessing a plurality of cutting blades and to prevent transmission of an occurable crack to a holder main body by using an inserted blade provided with an integrated shim with a defined acute corner. SOLUTION: A holder is provided with a fastening tool 33 and an inserted cutting blade 10 provided with a pocket including at least a shoulder in the radial direction. The inserted cutting blade 10 is formed into an octagonal base shape and provided with eight cutting blades 16 (16D, 16E, 16F, ...) formed by a transient part between the upper side face of the inserted blade and the blade face. The upper side face is provided with a plurality of projection parts. The projection parts facing each other separately from cooperating cutting blades are leant onto the fastening tool 33 when the inserted blade 10 is moved in the radial direction.

Abstract: PROBLEM TO BE SOLVED: To provide a wiper insertion tool and milling tool which can very accurately finish surfaces and is provided with a zone that prevent breaking from expanding. SOLUTION: Insertion tools 10 and 50 have an octagonal basic shape, and each of them includes at least three main cutting edges 16D-16F and 55A. Each of the tools 10 and 50 is provided with a step section so as to constitute an outlet zone at an end face. At least one of the insertion tools is a wiper insertion tool 50, and every other cutting edge is a main cutting edge 55A, which joins the wiper edge 55B between two main cutting edges. The first distance between wiper edges opposing to each other is longer than the second distance between the main cutting edges opposing to each other.

Abstract: The present invention relates to a milling cutter. The milling cutter comprises a holder and cutting inserts. The holder has a fastening device (33), a pocket comprising at least radial shoulder. The cutting insert (10) has an octagonal basic shape and includes eight cutting edges (16) created by the transition between an upper face (11) and an edge face (13) of the insert (10). The upper face (11) comprises a number of projections. A portion of the projection facing away from the associated cutting edge (16) is provided to abut against a fastening device (33) if the insert (10) is radially moved during milling. The invention further relates to a cutting insert (10), per se.

Abstract: The present invention relates to a milling cutter. The cutter comprises a holder and at least two cutting inserts. The cutting inserts (10;50) have a generally octagonal basic shape and each includes at least three major cutting edges (16,55A). An edge face of each insert is provided with a step which is provided so as to constitute an exit zone for a fracture. At least one of the cutting inserts is a wiper insert (50) and every other cutting edge of the wiper insert is a major cutting edge (55A) joining a wiper edge (55B) situated between two major cutting edges. A first distance of the wiper insert between two diametrically opposed wiper edges (55B) is larger than a second distance of the wiper insert between two diametrically opposed major cutting edges (55A). The invention further relates to a cutting insert (50), per se.

Abstract: The present invention relates to a cutting head (10) for chip removing machining comprising a first portion (14) for anchoring to a shank. The cutting head is provided with three cutting edges, which are integral with the cutting head. A central channel (34) extends in the cutting head towards a first free end (13) of the cutting head. The cutting head has three chip flutes. Each cutting edge is fed with flush medium via a hole (33), thereby providing three holes (33) terminating at the first free end (13) of the cutting head. The holes (33) intersect the central channel (34). One cutting edge (30) connects substantially to the axis of rotation (CL) of the cutting head.

Abstract: The invention relates to a cutting insert for chip forming machining, primarily for milling. The insert has an upper face (11), a lower face (12) and edge faces (13-16) therebetween. The upper face (11) is provided with a number of depressions spaced apart, said depressions (21) having a longitudinal extension in a direction that forms an angle ( alpha ) with a line perpendicular to the adherent cutting edge (18), said angle ( alpha ) being in the interval 5 DEG - 45 DEG . By this design a low wear of the cutting edge and consequently longer life even at higher temperatures can be achieved.
