    摘要: A prismatic and cylindrical cutting insert for long edge rotary milling applications has multiple indexable cutting edges ranging from four to six or even more depending on the actual milling applications. Each cutting edge of a prismatic or cylindrical cutting insert provides a positive cutting geometry and is equivalent to an indexable cutting edge of a traditional single-sided parallelogram-shaped cutting insert having two indexable cutting edges (often referred as A-Style insert). The prismatic and cylindrical (including tapered or conical) cutting insert may be used for machining a wide range of materials including difficult-to-machine materials, cast-iron and alloys, aluminum and alloys, carbon steels, and fiber reinforced composites.

    摘要: An indexable cutting insert having a triangular shape includes three sides and three cutting corners. A first planar surface and a second, parallel planar surface connects the three sides. In one embodiment, three major cutting edges are formed at an intersection between a respective side and the first planar surface. In another aspect, six major cutting edges are formed at an intersection between a respective side and the planar surfaces. In another aspect six major right-handed cutting edges and six major left-handed cutting edges are formed at an intersection between the sides and the first and second planar surfaces.

    摘要: A rotary cutting tool includes a cutter body, a coolant cap, and a retaining ring for removably securing the coolant cap to the cutter body. The coolant cap includes an outer surface, an inner surface and a generally cylindrical outer surface extending between the outer surface and the inner surface. The retaining ring is disposed within a retaining ring notch of the cutter body such that the outer surface of the coolant cap contacts the retaining ring when high pressure coolant is introduced into the cutter body to removably secure the coolant cap to the cutter body.

    摘要: In order to ensure good guidance of a drilling tool at the start of a drilling operation and at the same time ensure a reliable evacuation of a center chip, in the drill bit, in a tool flank adjoining a respective main cutting edge, an additional point thinning is recessed in the region of a transverse cutting edge, which additional point thinning, extending in a principal direction from the tool flank, merges, with a convex course, into a chip flute. As a result of the convex design, an as far as possible homogeneous, edge-free transition into the chip flute is obtained. Since the point thinning is additionally made, the tool flank, even in the rear end facing away from the cutting edge, remains at a front axial position, so that a second land is effective for a reliable guidance of the bore already at an axially front position.

    摘要: A cutting insert incorporates a pre-formed discrete cutting tip which wraps around a curved cutting corner of the insert. The cutting tip includes a top layer and a bottom layer made of a relatively harder material than the top layer. In one embodiment, the bottom layer is made of polycrystalline diamond (PCD) or a polycrystalline cubic boron nitride (CBN) material and the top layer is made of cemented carbide. The cutting insert may further incorporate a chip control structure formed in the cutting tip including a plurality of facets formed on each side of a centerline for providing chip control during a cutting operation. The chip control structure can be formed in a two-step process to expose a portion of the bottom layer. The discrete cutting tip can be brazed to the cutting insert prior to forming the chip control structure.
