摘要:
The present invention relates to an exchangeable insert seat member (6) for a metal cutting tool comprising a tool body (2) and a cutting insert (3), wherein the exchangeable insert seat member (6) is arranged to be placed between the tool body (2) and the cutting insert (3) wherein said exchangeable insert seat member (6) is contacting said tool body (2) and said cutting insert (3) at contact areas arranged such that there is no direct contact between the tool body (2) and the cutting insert (3) and wherein said exchangeable insert seat member (6) is produced by powder injection molding. The present invention also relates to a metal cutting tool comprising such an exchangeable insert seat member (6).

A cutter head (1) is equipped with cassettes (6) and cutting inserts (17) which can be fastened by means of one or more clamping wedges (7, 7a). On the rear side of the individual cassette there is a serration which co-operates with a serration (14) in a rear wall of a recess (5) for the cassette. A bottom wall (10) in the recess is divided into a plurality of part walls (10', 10''), which are spaced-apart by a first abutment surface (21) against which an analogous second abutment surface (22) on the cassette can be pressed. Thanks to this design, the cassette may be rapidly and simply mounted in a basic position in which it is held with good stability.

The machining of sets of rail-vehicle wheels by means of milling cutters is currently carried out with the milling-cutter axes parallel to the axis of the wheel set. Proposed is an end-milling cutter for machining wheel rims whose axis is disposed at right angles (16) to the axis (15) of the wheel set. The cross-sectional shape (17) of the wheel is duplicated on a disc-shaped body as a negative of the required wheel shape by means of a multiplicity of overlapping milling cutters duplicating the shape of the wheel, the cutters being spirally staggered round the pitch circles and designed to produce the wheel running-surface and the outwards-facing edge of the flange up to the tip of the flange or designed to produce the outwards-facing surface of the flange from the inside wheel surface to the tip of the flange. The invention is suitable for use in the bottom and top machining of wheel sets by either downcut or conventional milling.
摘要:
An improved cutting cartridge for rotary cutting tools is disclosed. The cutting cartridges are designed to be disposable and serve to permit the rotary cutting tools to be cheaply and quickly equipped with new cutting inserts without substantial effort, cost, or extensive time. The cutting cartridge essentially consists of a stator which is retained on a rotary cutting tool adapted to receive it. A rotor and a cutting insert are rotatably assembled on the stator and appropriately retained thereon.

Disclosed is a rotary slot milling cutter (20) having a plurality of cutting portions (30), each cutting portion (30) comprising an insert pocket (42) and a cutting insert (38) removably mounted therein. The cutting insert (38) comprises a top face (52) and a bottom face (54) comprising two spaced-apart abutments (92), with a ceiling (100) formed therebetween. The insert pocket (42) has a generally axially disposed pocket base (108) comprising two support surfaces (110, 110`) and a radially extending rib (112) disposed therebetween, the rib (112) comprising a roof (116) and two banks (114). When the cutting insert (38) is mounted in the insert pocket (42), the abutment platforms (96) abut the support surfaces (110, 110), and a gap (118) exists between the roof (116) of the rib (112) and the ceiling (100), and between each side slope (102) and adjacent banks (114).
