    摘要： The present invention relates to a cutting insert for shoulder milling cutting. The insert comprises rectangular end surfaces, first side surfaces and second side surfaces connecting the end surfaces and facing each other. First cutting edges and second cutting edges in the first side surface are diagonally symmetrical with respect to a first imaginary median plane, which transverses the middles of both the first side surfaces facing each other. The first cutting edges and the second cutting edges in the second side surface are diagonally symmetrical with respect to a second imaginary median plane, which transverses the middles of both the second side surfaces facing each other. The second cutting edge is offset toward the first median plane from the first cutting edge. The first cutting edge is offset toward the second median plane from the second cutting edge.

    摘要： The present invention relates to an internal groove insert. The internal groove insert comprises: a rectangular main body comprising a top surface, a lower surface, and first to fourth lateral surfaces; and first and second projections each projecting from the adjacent first and second lateral surfaces. The first projection has a first cutting edge at the side of the top surface of the main body, while the second projection has a second cutting edge at the side of the lower surface. The first and fourth lateral surfaces are inclined by an obtuse angle with respect to the top surface, while the second and third lateral surfaces are inclined by an acute angle with respect to the top surface. The central axis of the clamping hole is inclined to be parallel to the edge where the first and fourth lateral surfaces meet.

    摘要： The present invention provides a multi-functional cutting tool comprising a first cutting head, a second cutting head positioned opposite to the first cutting head, a shank formed between the first cutting head and the second cutting head, and a chip discharge portion extending from the first cutting head to the second cutting head by way of the shank. The first cutting head has 180 degrees rotational symmetry with the second cutting head about an axis, which passes through the longitudinal center of the cutting tool and is perpendicular to the central axis of the cutting tool. The chip discharge portion comprises a helical portion formed helically with respect to the central axis of the cutting tool such that the chip discharge portion is not positioned on the portion, where a tool holder clamps the cutting tool and a cutting load is concentrated during the cutting process.

    摘要： The present invention discloses a cutting insert for a machining tool having a structure being capable of controlling effectively chips generated on a work-piece. The cutting insert according to the present insert has an upper surface, a lower surface, a plurality of side surfaces connecting the upper surface and the lower surface and a central hole formed at a central portion thereof, and is characterized in that a flat seating surface is formed on a highest level of the upper surface; a plurality of side cutting edge portions are formed at border portions of the upper surface and the side surfaces; a corner cutting edge portion is formed at a border portion of two adjacent side cutting edge portions, the corner cutting edge portion has a cutting edge formed at a front end thereof; a land portion, a downward inclined surface, a corner bottom surface, a first protrusion, an upward inclined surface and the seating surface are formed on the corner cutting edge portion sequentially along a diagonal line directed from the cutting edge to the central hole; a pair of second protrusions are formed and disposed symmetrically on both sides of the diagonal line so that the corner bottom surface is surrounded by the downward inclined surface, the first protrusion, and the second protrusions; and the corner bottom surface has the smallest height and the seating surface has the largest height along the diagonal line.

    摘要： The present invention relates to a cutting tool capable of both drilling and internal/external turning. The cutting tool comprises a generally triangular-shaped cutting insert and a tool holder. On each side, the triangular-shaped cutting insert forms a major cutting edge and a minor cutting edge, which is shorter than said major cutting edge. Two adjacent major cutting edges form an angle of 60° therebetween, while adjacent major and minor cutting edges intersecting at a corner of the triangular shape of the cutting insert form an angle of 80 to 89° therebetween. The cutting insert is mounted in a pocket so that one of the major cutting edges of the cutting insert is projected in an axially forward direction of the tool holder, while the minor cutting edge on the side adjacent to the projected major cutting edge is projected in a radially outward direction of the tool holder.

    摘要： An insert according to the present disclosure comprises upper and lower surfaces joined by peripheral side surfaces provided with a through-hole extending between the upper and lower surfaces, each of the upper and lower surfaces comprising two raised portions and a central notch. The two raised portions adjoin two opposing side peripheral side surfaces, and extend along the entire length of the two opposing side peripheral side surfaces, and the upper surface comprises concave or convex surfaces curved along the two opposing side peripheral side surfaces. The central notch is formed as a flat plane between the two raised portions. The inserts according to the present invention are ground such that there is less removed volume during grinding and thus raw material can be saved. In addition, the grinding burden is much reduced compared with conventional inserts, and the service life can be increased.
