摘要： A milling cutting insert has a substantially triangular shape. The cutting insert contains a top side, an underside, and circumferential side surfaces extending between the top side and the underside. Cutting edges are formed at the transition of the circumferential side surfaces to the top side and/or the underside. On the circumferential side surfaces at least two discrete planar abutment surfaces are formed for positioning the cutting insert in a tool holder. The at least two discrete planar abutment surfaces are inclined with respect to each other at an outer angle of between 190° and 220° and the abutment surfaces are spaced from each other with respect to the circumferential direction of the cutting insert.

摘要： A thread cutting insert for cutting threads includes a plurality of cutting teeth disposed along a cutting portion, each cutting tooth is provided with an allocated chip former, and the chip formers are provided on a rake face of the thread cutting insert. The shape of at least two cutting teeth is different from each other. At least one cutting tooth along the cutting portion is provided with an allocated chip former the shape of which is adapted to the shape of that cutting tooth which, with respect to an order of engagement during cutting operation, precedes the subsequent cutting tooth along the cutting portion such that the at least one chip former has a shape adapted to the cross-section of chips encountered by it. A set of at least two thread cutting inserts, a thread cutting tool and a method for cutting threads, are also provided.

摘要： A cobalt-free, tungsten carbide-based cemented carbide material includes 70-97 wt % of hard substance particles formed at least predominantly by tungsten carbide, and 3-30 wt % of a metallic binder which is an iron-nickel-based alloy. The iron-nickel-based alloy includes at least iron, nickel and chromium, with a ratio of Fe to (Ni+Fe) of 0.70≤Fe/(Fe+Ni)≤0.95; a Cr content of 0.5 wt %≤Cr/(Fe+Ni+Cr) and (i) for the range 0.7≤Fe/(Fe+Ni)≤0.83: Cr/(Fe+Ni+Cr)≤(−0.625*(Fe/(Fe+Ni))+3.2688) wt %; (ii) for the range 0.83≤Fe/(Fe+Ni)≤0.85: Cr/(Fe+Ni+Cr)≤(−27.5*(Fe/(Fe+Ni))+25.575) wt %; and (iii) for the range 0.85≤Fe/(Fe+Ni)≤0.95: Cr/(Fe+Ni+Cr)≤2.2 wt %; an optional Mo content, an optional V content, and unavoidable impurities up to in total not more than 1 wt % of the cemented carbide material.

摘要： A cutting tool for severing a non-metallic material includes a holding element and a cutting element held on the holding element for cutting contact with the non-metallic material. A boundary region adjoins a holding material region of the holding element and a cutting material region of the cutting element. The precise severing of, for example, bone materials of human or animal origin, is possible in that a deformation resistance against an elastic deformation of the holding material region is greater than a deformation resistance against an elastic deformation of the cutting material region.

摘要： A double-sided milling cutting insert has a first cutting edge disposed at an intersection of a top side and a side surface and a second cutting edge disposed at an intersection of a bottom side and the side surface. Each of the first and second cutting edges contains three cutting edge portions which are useable by indexing. The cutting edge portions each have a cutting corner, a main cutting edge adjacent to one side of the cutting corner, and a wiper edge adjacent to the other side of the cutting corner. The main cutting edge and the wiper edge are each inclined towards a reference plane with increasing distance from the cutting corner such that the first and second cutting edges have the largest distance to the reference plane in the regions of the cutting corners. The side surface has main clearance surfaces, secondary clearance surfaces, and curved corner surfaces.

摘要： A clamping device is configured to clamp a cutting insert onto a holder of a cutting tool. The clamping device contains a clamping bolt and a locking bolt, wherein the clamping bolt is configured to be inserted into each of the cutting insert and the holder. The locking bolt is configured to be inserted into the holder, such that the locking bolt pre-strains the clamping bolt into clamping the cutting insert onto the holder. The clamping bolt is configured rotatable about a longitudinal clamping axis of the clamping bolt relative to each of the cutting insert and the locking bolt, such that the clamping bolt wedge engages with the locking bolt during a clamping bolt rotation about the longitudinal clamping axis.
