A cutting insert for machining has a substantially cylindrical main body with an axis, a lateral flank and opposing rake faces. Cutting edges are formed at the intersection of the flank and rake faces. The cutting edges have, in the direction of the axis, in each case at least two convexly curved sections which are connected together by concavely curved or substantially straight sections.

Cutting insert for machining

A drill cutting insert has a cutting edge at a transition between a side surface and a top side which is formed with n identical cutting corners and n identical partial cutting edges &#x2014;with n&#x3b5;{} &#x2014;extending between the cutting corners. Each of the n partial cutting edges has: adjoining a first cutting corner, a main lip which is straight in plan view of the top side; adjoining the other cutting corner, a secondary lip which is straight in plain view of the top side, and a transition section, via which the main lip and the secondary lip merge into one another and which has a convex section adjoining the main lip and a concave section adjoining the secondary lip. The main and secondary lips enclose on the outside an angle a &#x3b1;&#x3c;180&#xb0; in plan view of the top side.

Drill cutting insert

A cutting tool has a main tool body and at least one insert seat disposed thereon. The seat has a bottom surface for mounting a cutting insert, and further has a dowel pin, which penetrates a through-hole of the mounted cutting insert and the bottom surface and can be fixed to the main tool body. A center longitudinal axis of the fixed dowel pin is arranged at an acute angle with respect to the bottom surface. The dowel pin contains a spherical segment for mounting on a bearing surface of the through-hole. The surface of the spherical segment is interrupted by a segment groove.

Cutting tool

A tool for machining is made from a hard-metal, cermet or ceramic base material and a single-layer or multi-layer hard material coating on the base material. An additional coating of one or more metals from the group of aluminum, copper, zinc, titanium, nickel, tin or base alloys of these metals is applied to the hard material coating.

Tool for machining

A cutting insert for a machining cutting tool. In a radial direction Q, which extends in a main plane H from the cutting corner to a center Z of the cutting insert, the following are formed in order: a falling cutting surface, a chip guiding stage base adjacent the cutting surface, a first chip guiding stage, which is adjacent to the chip guiding stage base and has a first surface rising from the chip guiding stage base and a first plateau adjacent thereto. A second chip guiding stage has a second surface rising from the first plateau and a second plateau adjacent thereto. A third chip guiding stage has a third surface rising from the second plateau and a third plateau adjacent thereto.

Cutting insert for a cutting tool

A coated article, in particular a tool for cutting machining, has at least one titanium diboride layer which has been deposited by a thermal CVD process and has a thickness of at least 0.1 &#x3bc;m. The titanium diboride layer has an extremely fine-grained microstructure with an average grain size of not more than 50 nm.

Coated article

A cutting insert includes a plurality of consecutively disposed, interlinked individual cutting inserts that can be brought into use successively through a respectively interposed predetermined breaking point by detaching a respectively preceding individual cutting insert in cutting use. The cutting insert has a blade-shaped construction with lower and upper bearing surfaces for being held in an elongated cutout with lower and upper opposing surfaces in a basic tool body of a grooving and cut-off tool or disk milling cutter. Each individual cutting insert is provided with a positioning device that cooperates with a complementary positioning device of the basic tool body. A grooving and cut-off tool or disk milling cutter and a wrench for the cutting insert, are also provided.

A milling tool has a cutting edge geometry with a main cutting edge, a cutting corner, optionally with a bordering planar cutting edge segment, and a secondary cutting edge. The tool is used for milling to achieve the smoothest level surface possible parallel to the rotational axis of the milling tool. Each main cutting edge is formed to result in a generatrix of the envelope curve described by the rotation of the milling tool that has a first outwardly curving segment and a second inwardly curving segment. The first segment increases in its distance from the rotational axis from the beginning of the segment to the end of the segment. The distance of the second segment decreases from its beginning towards its end. The tangents at each point of the second segment encompass an angle &#x3b1;of more than 0&#xb0; and up to 3&#xb0; with a parallel to the rotational axis.
