A cutting tool including a basic body and a plurality of cutting inserts arranged in series one after the other. Each insert includes a topside, an underside, two opposite side surfaces, front and rear ends, and a cutting edge adjacent to the front end. The rear end of a first cutting insert faces the front end of a second cutting insert disposed rearward of the first insert, and a chip space forward of the cutting edge of the second cutting insert is delimited by a chip-forming surface extending in the forward direction from the rear end of the first cutting insert, and a chip-forming surface extending downward from the cutting edge of the second cutting insert.

Tool and a cutting insert for chip removing machining

A face-milling insert, including a chip-removing main cutting edge adjacent to a first clearance surface, and a surface-wiping secondary edge adjacent to a second clearance surface, the main cutting edge forming an angle of 45&#xb0; with an imaginary straight line in the extension of the secondary edge. Adjacent to a third clearance surface, an intermediate cutting edge is formed between the main cutting edge and the secondary edge, the intermediate cutting edge being shorter than the main cutting edge and forming an angle within a range of 20-40&#xb0; with the extension line. The intermediate cutting edge transforms into the adjacent edges via arched part edges adjacent to convex clearance surfaces.

Face milling insert

A cutting insert preferably for milling of extremely highly alloyed grey cast iron, of a substrate and a coating and methods of making and using the insert are disclosed. The cemented carbide substrate includes WC, of from about 3 to about 8 weight-% Co and less than about 0.5 weight-% carbides of metals from groups IVb, Vb or VIb of the periodic table. The coating has

Coated cutting insert

Coated milling inserts particularly useful for milling of grey cast iron with or without cast skin under dry conditions at generally high cutting speeds and milling of nodular cast iron and compacted graphite iron with or without cast skin under dry conditions at rather high cutting speeds are disclosed. The inserts are characterised by a WC&#x2014;Co cemented carbide with a low content of cubic carbides and a highly W-alloyed binder phase and a coating including an inner layer of TiCNwith columnar grains followed by a wet blasted layer of &#x3b1;-AlO.

Coated inserts for dry milling

Coated milling inserts particularly useful for milling of highly alloyed grey cast iron with or without cast skin under wet conditions at preferably rather high cutting speeds and milling of nodular cast iron and compacted graphite iron with or without cast skin under wet conditions at moderate cutting speeds are disclosed. The inserts are characterised by a WC&#x2014;Co cemented carbide with a low content of cubic carbides and a highly W-alloyed binder phase and a coating including an inner layer of TiCNwith columnar grains followed by a layer of &#x3ba;-AlOand a top layer of TiN.

Coated inserts for wet milling

Coated cemented carbide cutting tool inserts for bimetal machining under wet conditions at moderate cutting speeds, and in particular, cutting tool inserts for face milling of engine blocks formed from alloys of cast iron and aluminium and/or magnesium. The inserts are characterized by a submicron WC&#x2014;Co cemented carbide and a coating including an inner layer of TiCNwith columnar grains followed by a layer of &#x3ba;-AlOand a top layer of TiN.

The coated milling insert is particularly useful for milling of grey cast iron with or without cast skin under wet conditions at low and moderate cutting speeds and milling of nodular cast iron and compacted graphite iron with or without cast skin under wet conditions at moderate cutting speeds.

Coated inserts for rough milling

Coated milling insert has a WC-Co cemented carbide with a low content of cubic carbides and a highly W-alloyed binder phase and a coating including an inner layer of TiCNwith columnar grains followed by a layer of &#x3ba;-AlOand a top layer of TiN. The coated milling insert is particularly useful for milling of grey cast iron with or without cast skin under wet conditions at low and moderate cutting speeds and milling of nodular cast iron and compacted graphite iron with or without cast skin under wet conditions at moderate cutting speeds.

The present invention relates to a cutting tool insert for side and face milling of rolled low alloyed steel at low and at moderate cutting speeds comprising a cemented carbide body and a coating and a method for making same. The cemented carbide body comprises WC, from about 7.3 to about 7.9 wt-% Co and from about 1.0 to about 1.8 wt-% cubic carbides of Ta and Nb and a highly W-alloyed binder phase with a CW-ratio of from about 0.86 to about 0.94. The coating comprises: The invention also relates to the use of such a cutting tool insert for side and face milling of rolled low alloyed steel at low and moderate cutting speeds.

Cutting tool insert

A tool for the fine-turning of grooves in workpieces including a basic body having a rearwardly extending mounting part, and a forwardly projecting bracket. The bracket includes a narrow neck part and an enlarged support part disposed at an end of the neck part. The support part, which forms an insert seat, extends laterally from the neck part wherein the seat is arranged asymmetrically with respect to an imaginary center line of the basic body. A cutting insert includes a bottom side supported on the insert seat. The insert includes two spaced apart convexly arched side cutting edges arranged so that the imaginary center line passes therebetween. A hole is provided through the insert for receiving a fastening screw. The bottom side and the insert seat include mutually engaging stabilizing structures preventing angular displacement of the insert about an axis of the hole.

Tool and cutting insert for the fine turning of grooves in workpieces

A method of loading cutting tool inserts in a PVD (Physical Vapor Deposition) coating equipment consists in using a tube manufactured of a non-magnetic metallic material surrounding a stack of alternating discs of a magnetic material and iron. The north poles of the magnets are directed towards each other and the cutting inserts are positioned on the outer wall of the solid tube and kept in place by the magnetic forces.

Fixture and loading method for PVD coating of cutting tool inserts

The present invention relates to a method of milling a material comprising aluminum and cast iron. By using a silicon nitride based cutting tool insert at a cutting speed of more than 1000 m/min, an unexpected increase in tool life has been obtained.

Method of milling engine blocks

Coated milling insert has a WC&mdash;Co cemented carbide with a low content of cubic carbides and a highly W-alloyed binder phase and a coating including an inner layer of TiC N with columnar grains followed by a layer of &kgr;-Al O and a top layer of TiN. The coated milling insert is particularly useful for milling of grey cast iron with or without cast skin under wet conditions at low and moderate cutting speeds and milling of nodular cast iron and compacted graphite iron with or without cast skin under wet conditions at moderate cutting speeds.
