摘要: An uncoated cutting tool that comprises a body containing a pocket. A polycrystalline cubic boron nitride blank has a cutting tip. The blank is brazed into the pocket using a braze alloy whereby there is a braze joint between the body and the polycrystalline cubic boron nitride blank. The braze alloy has a liquidus temperature of at least about 900 degrees Centigrade wherein the braze alloy is selected from the group comprising a nickel-gold braze alloy containing nickel and gold, a copper-gold braze alloy containing copper and gold, a silver-titanium braze alloy containing silver and titanium, and a silver-palladium braze alloy containing silver and palladium.

摘要: A thread-cutting insert comprises opposite top and bottom sides as well as front and back sides, the front one of which is formed with a plurality of laterally spaced-apart teeth, which separately have a chip-removing edge in a transition between a clearance surface and a top surface of the individual tooth, one the of the teeth, viz. a final-shaping tooth, having a contour shape that gives the desired profile shape of the thread that is to be generated. At least one downwardly open duct is formed in the bottom side of the cutting insert, which duct extends up to the final-shaping tooth and ends adjacent to the same. Advantageously, such ducts are formed for all teeth.

摘要: The invention concerns a process for the manufacture of a cutting insert (1) for thread cutting, with several cutting teeth (2-6) simultaneously engaged in incrementally cutting the thread profile. The blank is manufactured by pressing and sintering so that the relief angles of the flanks of the side cutting edges (9,10) of the individual teeth (2-6) are at least 3.degree. and the profile depth of the final cutting tooth (6) which makes the finishing cut on the thread fits within the required final measurement tolerances, while the thickness of the cutting insert (1) and the tooth width (b) of the cutting teeth (2, 3, 4, 5, 6) are oversized. Subsequently, the blank is mechanically processed on the back face (7) and/or the front face (8) until the tooth width (b) of the cutting teeth (2, 3, 4, 5, 6) and the thickness (d) of the cutting insert (1) fit within the required final measurement tolerances.

摘要: A thread cutting insert comprises a center portion and a plurality of cutting corners project outwardly from the center portion. Each cutting corner comprises a pair of outwardly converging cutting edges which are joined together by a curved tip. Each cutting corner includes a chipbreaking protrusion extending upwardly higher than the upper face of the center portion of the insert. The protrusion includes a front portion facing the tip, and a pair of upwardly converging sides. The front portion and sides are spacially confined to the cutting corner.

摘要: A single-sided cutting insert preferably for thread chasing, the lower face of which comprises three support surfaces inclining towards the center of the lower face and a recess separating them. The support surfaces are projecting partly around the recess and therefore the cutting insert at insertion against a base surface of a cutting insert site in a tool shank abuts only against the planar base surface in three separated points.

摘要: A tool holder has a pocket formed therein into which a cutting insert is mounted by a clamp and fastening means. The cutting insert has a wedge shaped recess which extends from the outside surface of the insert and intersects with the upper surface along a line substantially equidistant from the outside surface. The clamp includes two leg portions, the first leg portion being retained in a recess formed in the tool holder and the second leg portion being inserted in and complementary to the wedge shaped recess of the insert. Initial and secondary restraining forces are exerted on the insert when the clamp is fastened to the tool holder.

摘要: A threading tool is disclosed featuring the combined utilization of a multi-toothed thread chaser insert with a single point indexable thread chaser insert. In generating a desired thread form, successive teeth of the multi-toothed chaser perform the initial cutting passes on a workpiece, while the tooth of the single tooth chaser performs the final finishing cutting operation.
