摘要: An indexable cutting insert has opposing first and second polygonal end surfaces (2, 3) connected by a peripheral side surface (4). Sets of cutting edges (5) are formed at the intersection of each end surface with the peripheral side surface. Each set of cutting edges includes a corner cutting edge (6), first and second cutting edges (7), (8) on opposite sides of the corner cutting edge (6) and a wiper edge (9) formed between the second cutting edge (8) and the corner cutting edge (6). The peripheral side surface (14) includes a wiper-edge side surface (14) having constant width as it extends between the first and second end surfaces (2, 3). A boundary of the wiper-edge side surface (14) with a second side surface below the second cutting edge (8) is inclined with respect to a direction perpendicular to the first end surface.

摘要: A cutting insert is provided with a plurality of cutting portions formed at the intersection portion of each end surface and a peripheral surface. Each cutting portion includes first and second cutting edges. First corners and second corners which differ in their internal angles are alternately formed in each end surface. An internal angle of the first corner is smaller than an internal angle of the second corner. Each first cutting edge has a portion extending to approach the median plane as a distance from a corresponding first corner increases. A first side surface portion extending on the peripheral surface from each first cutting edge forms an insert internal obtuse angle, and a second side surface portion extending on the peripheral surface from each second cutting edge forms an insert internal acute angle.

摘要: An indexable cutting insert includes a rake face, a flank surface, a bottom surface, and a central aperture defined by an aperture side wall. The indexable cutting insert further has a mouth defined by a mouth surface. There is a primary coolant trough that has an aperture section in the side wall contained in the aperture side wall, a mouth section contained in the mouth surface, and a rake face section contained in the rake face. There is a radial angular coolant trough, which has an entrance end opening into a selected one of the primary coolant trough and the mouth. The radial angular coolant trough has an orientation wherein the central longitudinal axis thereof is generally perpendicular to a corresponding discrete cutting edge whereby during operation a coolant stream is directed toward the corresponding discrete cutting edge.

摘要: A cutting insert is used in a cutting edge replaceable rotary cutting tool. The cutting insert includes a first cutting edge formed on an intersecting ridge portion between a first end surface of two opposite end surfaces and a circumferential side surface, and a first depressed portion formed along a part of the first cutting edge. The first depressed portion is provided to form a larger rake angle at the first cutting edge than that at a part not having the first depressed portion of the first cutting edge.

摘要: An indexable insert for drilling includes front and rear edges opposite to each other and having a rotationally symmetrical relation; and two side surfaces opposite to each other and having a rotationally symmetrical relation. Each side surface has first and second cutting edge portions formed thereon. The first cutting edge portion is disposed farther than the second cutting edge from the center of the blank insert, thereby providing a step between the first and second cutting edge. The first cutting edge is adjacent to the front edge.

摘要: An insert tip used when steel or cast iron is worked, in which clearance portions are provided inside bolt holes formed in the insert tip to slantingly fit a bolt into the bolt holes, the bolt serving to fix the insert tip to a cutter body, so that more insert tips can be firmly fixed to the cutter body. To this end, in an insert tip including bolt holes that cause upper and lower surfaces of a plate shaped body to communicate with each other, the plate shaped body having a cutting edge at each corner portion, the insert tip being fixed to a cutter body by a bolt fitted into the bolt holes, clearance portions are formed at a portion direction toward each corner portion of the insert tip among inner side portions of the bolt holes to prevent interference between the bolt holes and the bolt if the bolt is slantingly fitted from one corner portion of the insert tip, where the insert tip is worked, to its opposite corner portion.
