Abstract: A cutting insert used for cutting metal, especially for milling camshafts. The insert comprises at least one cutting edge that is formed by the intersection of a face with a flank. The cutting edges extend at an angle deviating from 90° relative to the cutting direction of the cutting insert in order to reduce the noise level during machining.

Abstract: A cutter insert for disc-milling cutters, in particular, for milling crankshafts. The insert has upper and lower surfaces and circumferential lateral surfaces, which connect the upper and lower surfaces to one another. The insert includes raised swellings and/or projections on the upper surface, at least in the region of two corners, which preferably extend over the entire length of one side of the cutter insert, so that, in a view perpendicularly toward a cutting face formed by at least one of the lateral surfaces, the edge which defines the transition from the upper surface to the cutting face, has a portion projecting relative to the central edge section in the region of each of the two ends of this edge.

Abstract: A cutting insert comprises first and second polygonally-shaped main faces arranged substantially parallel to one another, and a side face structure interconnecting the first and second main faces to define a peripheral edge. At least the first main face includes at least one projection extending to the peripheral edge, the projection formed by: a portion of the first main surface (defining a relief surface), a portion of the side face structure (defining a rake surface), and a portion of the peripheral edge (defining a cutting edge). The insert includes support surfaces defined by a portion of the second main face, and by portions of the side surface structure other than the rake surface.

Abstract: A cutting insert for milling cam shafts includes first and second surface interconnected by a third surface, and at least one cutting edge. The cutting edge includes a straight first cutting edge section, a straight second cutting edge section, and a generally convex third cutting edge section, all adjoining one another. The first section extends along the junction between the first and third surfaces. The second section extends along the junction and includes a first end adjoining an end of the first section. The second is inclined at an obtuse angle from one end of the first section in a direction away from the third surface. The third section extends along the junction and adjoins a second end of the second section. The third section is of generally convex shape and extends over an angular range greater than 90°. The first, second and third sections lie in the third surface.

Abstract: A milling cutter for machining camshafts includes a rotary disc and an annular row of cutting bits mounted in pockets formed in the disc. Each cutting bit includes a top surface having a pair of diagonally spaced raised portions. Cutting edges are formed where the top surface and the raised portions intersect side surfaces of the bit. The pockets are arranged along an edge of the disc where a cylindrical outer periphery of the disc intersects an end face of the disc. Each pocket is configured with an internal cavity for receiving a raised portion of an inactive cutting portion of the respective bit.

Abstract: A cutting bit has the basic form of a prism, including two substantially parallel top and bottom surfaces and at least three lateral surfaces running substantially perpendicular to the top and bottom surfaces. A cutting edge is embodied in the transition area from at least one of the lateral surfaces to the top or bottom surface and wherein the at least one lateral surface has alternate projecting and recoiling sections viewed from above or from below. Effective main cutting edges are embodied at least in the area of the projecting sections, and wherein optionally secondary cutting edges extend from the relatively projecting main cutting edges backwards along the recoiling sections for at least at a given cutting depth.

Abstract: The invention relates to a cutting insert, especially for milling camshafts, said cutting insert having at least one cutting edge. The aim of the invention is provide a cutting insert that allows for considerable savings as compared to conventional cutting inserts.

Abstract: The invention relates to a cutting insert used for cutting metal, especially for milling for example camshafts. The inventive insert comprises at least one cutting edge (4, 4′) that is formed by the intersection of a face (2) with a flank (3). The aim of the invention is to provide a cutting insert for a milling cutter and a corresponding milling cutter the noise level of which, even if at full load, is considerably reduced for high-speed milling. To this end, the cutting edges (4, 4′) extend at an angle deviating from 90° relative to the cutting direction of the cutting insert.

Abstract: A rotary metal-cutting tool includes a tool body and a cartridge carrying a cutting insert that is adjustable in relation to the tool body. The adjustment is accomplished by providing a serration on one side surface of the cartridge and a correspondingly curved recess in the tool body adjacent the serration for the receipt of a key element. The key element has teeth engageable with the serration such that rotation of the key produces adjustment of the cartridge and insert.

Abstract: A milling cutter for metal cutting having a cutter body (1) in which inserts (5) are retained in recesses (3) solely by spring means (7-11). An edge (27) of the insert (5) is supported in the recess (3) on an axially displaceable adjusting device (6) which has a somewhat inclined contact surface (13). The insert (5) is adjustable without the need of loosening any clamping device.

Abstract: An internal disk milling cutter for the milling of workpieces includes a one-piece annular base body. Insertable tool bit holders are arranged around a circumferentially internal surface of the annular base. Most of the holders are in the shape of circular segments and have frontal surfaces engaging the frontal surfaces of the adjacent holders. One holder has frontal surfaces which are non-diverging in the radially outward direction. An adjacent holder has a frontal surface of the one holder. A clamp wedge is disposed in either of such opposing frontal surfaces to clamp all of the holders circumferentially together. The holders bear radially outwardly against the base at circumferentially spaced locations which are in the vicinity of the frontal surfaces.

Abstract: A cutter head, for high speed face-milling cutting, with cutting plates pressable by centrifugal force against recess walls of the cutter head body. The cutting plates are arranged in recesses, of the cutter head body, with walls directed radially outwardly toward each other and having a dovetailed cross section tapering toward the chip space, the cutting plates being respectively held by a clamping piece having an inclined surface which is located opposite the free surface of the cutting plates. The cutting plates, which may be multiply arranged in common radial planes, are identical and are disposed with their cutting edges in a common tangential plane. Adjacent cutting plates of one radial plane, and forming a row, may be axially longitudinally displaced relative to the cutting plates of a second or third radial plane.

Abstract: A mounting element is disclosed, for use in supporting a reversible cutting tip in a tool body. The supporting element comprises a cylindrical portion configured to be inserted radially into a tool body and form an axial mounting for the tool tip. An arm portion is connected to the projects at substantially a right angle therefrom to form a radial mounting for the tool tip.
