摘要： A cutting insert according to an embodiment of the present invention is a double-sided cutting insert comprising an upper surface, a lower surface, a side surface, a cutting edge, and a mounting hole penetrating the upper surface and the lower surface, in which the upper surface is provided with a single upper surface boss portion that surrounds the mounting hole and is flat, the cutting edge includes a main cutting edge, a corner cutting edge extending from the main cutting edge, a sub-cutting edge extending from the corner cutting edge, and a side portion extending from the sub-cutting edge, a first main cutting edge flank surface extending from the main cutting edge forms an acute angle with an extension line of the upper surface boss portion, a sub-cutting edge chip breaker surface extending from the sub-cutting edge is at a gradually increasing angle with the extension line of the upper surface boss portion, as the sub-cutting edge chip breaker surface is distanced away from the corner cutting edge, and when the cutting insert is viewed into the upper surface, a side portion surface extending from the side portion is concavely recessed.

摘要： A cutting insert 2 comprises a peripheral side surface 30 which is parallel to a central axis O of a first end surface 10 and a second end surface 20. The peripheral side surface 30 comprises a first side surface 31 facing a first major cutting edge 11, a second side surface 32 facing a first wiper edge 12, and a third side surface 33 facing a first inner edge 13. A flank 311 of the first major cutting edge 11 and a flank 321 of the first wiper edge 12 are inclined such that the flank 311 and 321 approaches the central axis O as it heads toward the first end surface 10. The flank 311 of the first major cutting edge 11 is located on a different plane from the first side surface 31. The flank 321 of the first wiper edge 12 is located on a different plane from the second side surface 32. Meanwhile, a flank of the first inner edge 13 is located on the same plane as the third side surface 33.

摘要： A beveling cutter (1) is provided in which a cutting blade (10) is composed of, when seen from an axial direction (X): an inner cutting blade portion (16) extending linearly toward a rear side R2 in a rotational direction R and toward the outer peripheral side; an outer cutting blade portion (17) extending linearly toward a forward side (R1) in the rotational direction (R) and toward the outer peripheral side on the radially outer side of the inner cutting blade portion (16); and a bending cutting blade portion (18) that connects the outer peripheral end of the inner cutting blade portion (16) with the inner peripheral end of the outer cutting blade portion (17). During a beveling operation, a cutting force vector (V1) applied from the inner cutting blade portion (16) to an edge portion (3) of a workpiece (2) and a cutting force vector (V2) applied from the outer cutting blade portion (17) to the edge portion (3) of the workpiece (2) are directed toward the center in the width direction of a bevel (5) formed by cutting. Formation of Poisson burr can thus be suppressed.

摘要： An assembled chamfer mill comprises a tool holder, an extension shaft, and chamfer bits locked to two ends of the extension shaft. The chamfer bits each have upper blades and lower blades for chamfering the edges of a workpiece simultaneously. The length of a shaft body of the extension shaft may be set in various sizes. Depending on the thickness and shape of the workpiece, the shaft body having an appropriate length is selected, so as to control the distance between the two chamfer bits. Another extension shaft may be provided to connect a further chamber bit for chamfering the edges of the workpiece simultaneously.

摘要： The present invention relates to a method for producing a fiber-plastics-composite tool component (1) having a matrix system (6) that has embedded fibers, PBO fibers (4) being selected as the fiber component and a thermosetting plastics matrix (8) being used as the matrix component of the matrix system (6) (S1), which thermosetting plastics matrix has such adhesion to the PBO fibers (4) in the hardened fiber-plastics composite (2) that the coefficient of thermal expansion of the PBO fibers (4) is imparted to the matrix system (6). The invention also relates to a load-bearing tool component (1) of a chip-removing tool in the design of a fiber-plastics-composite press-molded part, the load-bearing tool component (1) comprising a matrix system (6) that has a thermosetting matrix component (8) and comprising PBO fibers (4) embedded into said thermosetting matrix component.

摘要： A cutting insert has an upper surface (21), a lower surface (91) and a side surface (61) that connects the two surfaces. A cutting edge is formed at an intersecting edge between the upper surface (21) and the side surface (61). The cutting edge includes at least a major cutting edge (33), a corner edge (34) connected to the major cutting edge (33), and a curved wiper edge (35) located on the opposite side of the major cutting edge (33) across the corner edge (34). A first angle θ made by the major cutting edge (33) and the chord of the wiper edge (35) is 155°≤θ

摘要： An indexable milling or drilling insert having a 180-degree rotational symmetry about each of the first, second and third axes (X, Y, Z) of a three-dimensional euclidean space. The insert has opposite first and second main surfaces and a peripheral surface extending therebetween. Each main surface has a main abutment surface and at least two rake surfaces. The insert has a through clamping bore which extends along the third axis and opens out to the main surfaces. The peripheral surface has two opposite front surfaces connected to two opposite side surfaces. Each front surface has a pair of outward abutment surfaces and each side surface has a pair of at least partially planar inward abutment surfaces. Each pair of outward abutment surfaces converge outwardly away from the third axis and each pair of inward abutment surfaces converge inwardly towards the third axis.
