摘要： A milling tool (1) has at least one insert seat (14) which is adjustable in the axial direction. Provided for this purpose as an insert seat is a cartridge (47) which is received in a groove (41) but does not have a supporting face for the bottom face of the insert (25). The insert (25) consequently rests on a side wall (42) of the groove (41). As a result, the insert seat (14) is formed by a combination of the plane face of the tool body (2) and bearing faces (51, 52) of the cartridge (47). This achieves a particularly small installation space (close tooth spacing) and rigid mounting of the insert (25).

摘要： To facilitate manufacture and stocking of inserts for the ball end of a ball milling cutter, identical asymmetrical cutting inserts which are of generally pointed, elongated leaf shape, define two end points or tips, with two cutting edges opposite a theoretical straight line connecting the tips. The cutting edges (14, 15) each have at least one curved portion (24, 26) and an adjoining elongated, roughly straight portion (23, 25). The lengths of the respective curved portions and straight portions on the two cutting edges are different, and the edges and their respective lengths and positions with respect to an attachment hole (17) are so arranged that the first cutting edge of one insert on one side cuts on a ball surface which extends at least up to approximately the center line of the milling tool, and the straight cutting edge merges into a cylindrical surface. The curved portion (26) of the other cutting edge (15) of a second, identical insert completes the ball cutting surface and also merges into a cylindrical surface, so that, in operation, one longer and one shorter curved portion, respectively, on both inserts are actively cutting. When the cutting edges are worn, the inserts are interchanged on the respective plate seats of the milling cutter so that the previously inactive shorter or longer curved edge, cut at the end surface.

摘要： A cutting bit formed as a round plate for a material removal tool has a base body, which is defined by a bottom face, a top opposite it and spaced apart from it, and a side face between them. The side face, with a chip face located on the top, defines a circular cutting edge. For securing the bit, a central opening which can receive a securing screw, for instance, is provided. To secure the cutting bit in a tool body in a manner fixed against relative rotation, a plurality of depressions, for instance, are provided on the top of the cutting bit and can be engaged by a clamping claw supported on the tool body. Circumferential forces engaging the cutting bit are diverted by way of these depressions, thus preventing torsion or twisting of the cutting bit.

摘要： An improved slot-drilling cutter has a tool body with plate seats at the end, which are arranged symmetrically in respect to each other. Cutting plates are arranged on the seats, whose cutting edges, as well as possibly cutting edges 41, 42, are set identically, i.e. which cover each other completely in the circumferential direction. Because of this, respectively two cutting edges are active for the drilling operation, as well as for the milling operation, which increases the metal cutting yield and allows the same advancement when drilling, as well as when milling. The slot-drilling cutter is free of lateral forces because of the symmetrical design, which permits a high degree of working precision in spite of large advancement moves.

摘要： A cutting bit, in particular an indexable cutting bit, has a polygonal base body with a flat bottom side (1), a flat or structured top side (4) spaced apart from the bottom side, and a number of side surfaces (2) adjoining one another, forming corners (3). On the top side, the base body is beveled to descend in the outward direction of the region of the chip removing surface at at least one corner (3), in such a way that at the corner a delimited region (9) is formed that is inclined with respect to the bottom side (1). In this inclined region (9), on one side of the corner (3), the main cutting edge (5a , 5b) extends to the vicinity of the corner (3), while on the other side of the corner in the inclined region a plane, or facing, cutting edge (5c) is formed, which essentially adjoins the main cutting edge, and the portion of the main cutting edge located in the inclined region (9) has essentially at most the same length as the plane cutting edge.

摘要： In a cutting insert, cutting edge (9) is formed by the junction of a chip face (21, 22) and a flank (15). The flank is an extension of a straight portion (11) of a side face (5, 6) which begins at the base (2). Rather than remaining straight throughout the side face, straight portion (11) leads into a transitional face (13) used to form a strip (17), the face of which is the flank (15). Thus, the flank (15) is raised relative to an imaginary lengthening of the side face portion (11).

摘要： To permit boring with replaceable cutter elements (10, 10a, 10b), particularly into materials where, upon withdrawal of the boring tool from a bore hole (40), grooves or scratches are to be avoided, two cutter elements are positioned on a fluted cylindrical body (1), the cutter elements being so located that the inner cutter element (10b) is positioned on the body so that an effective cutting edge (19) thereof is radially inwardly of the theoretical circle (33) formed by the outer cutter element (10a) upon rotation of the tool, the cutting corner of each cutter element is formed as a relieved or chamfered corner (15) and forms a chopped corner cutting edge (22). Both cutter elements (10a, 10b) are so positioned on the body that the chopped corner cutting edges are located at least in part on a diametrical plane (34) passing through the axis of rotation (31) of the body, and the inner cutter element, additionally, is so located that its chopped corner cutting edge (22 ) is located in the immediate vicinity of, at, or intersects the axis of rotation (31) of the body. The outer cutter element is so positioned that a corner cutting edge portion (23) projects beyond the circumference of the boring tool and it is oriented such that the main cutting edge portion (19) thereof extends along a chord with respect to the theoretical circle (33).

摘要： Cutting elements or cutter chips (7, 8) are located on a tool body (1). Cutting chip removal spaces (14, 15) are formed in the tool body in three segments. A first segment (I) adjoins the end face (4) of the drill body and includes at least one cutting element seat (10, 11); a chip removal space extends axially, i.e. straight, or slightly obliquely fluted. A second segment (II), adjacent thereto, is formed partially helically with a twist (21) of less than 90.degree. relative to the tool body axis; the second segment (II) terminates axially at a point where, in operation, the direction of radially acting cutting forces coincides essentially with the primary axis of inertia (0-0) of the geometrical moment of inertia. A third segment (III) adjoins the second segment (II); it is essentially straight-fluted.
