摘要： A cutting insert has a top surface, a bottom surface, a plurality of side surfaces that connect the top and bottom surfaces. The side surfaces form an obtuse angle with the bottom surface as well as an acute angle with the top surface. The side surfaces include a first side surface and a second side surface, which form an obtuse angle with each other when seen from the above. A main cutting edge is formed at an intersection between the first side surface and the top surface. An inclined cutting edge, which is only for ramp milling, and a minor cutting edge are formed at an intersection between the second side surface and the top surface. An obtuse angle, which the second side surface forms with the bottom surface, is greater than that which the first side surface forms with the bottom surface.

摘要： A cutting insert has top and bottom surfaces in the thicknesswise direction, and front and rear surfaces in the widthwise direction. First and second cutting edges are formed in the lengthwise direction at intersection portions where the top surface intersects with the front and rear surfaces. Third and fourth cutting edges are formed in the lengthwise direction at intersection portions where the bottom surface intersects with the front and rear surfaces. The first to fourth cutting edges are divided by a plurality of recesses. The plurality of recesses are symmetric with respect to the lengthwise centerline (A), which runs between the first and third cutting edges on the front surface and are asymmetric with respect to the thicknesswise centerline (B) perpendicular to the lengthwise centerline (A).

摘要： A cutting insert has a top surface and a bottom surface having a parallelogram shape, and four side surfaces connecting the top and bottom surfaces. One or more primary cutting edges are formed at intersections between the top and bottom surfaces and two opposing side surfaces. Secondary cutting edges are formed at intersections between the top and bottom surfaces and two other opposing side surfaces. The primary cutting edge forms a first angle with respect to a median plane parallel to the top and bottom surfaces. The secondary cutting edge forms a second angle with respect to the median plane. The top and bottom surfaces have a mounting surface and a rack surface, wherein the rack surface extends inwardly from the cutting edge toward the median plane. The top and bottom surfaces of the cutting insert have mirror symmetry with respect to the median plane.

摘要： A cutting insert having a plurality of corner cutting edges has an upper face, a lower face, two longitudinal side faces and two transversal side faces connecting the upper face and the lower face. A through hole passes through central parts of the upper face and the lower face. The longitudinal side faces are opposite to each other and normal to both upper and lower faces, as are the transversal side faces. The upper face and the lower face are each provided with two chip discharge grooves, each chip discharge groove extending along a corresponding one of the transversal side faces, the two chip discharge grooves being inclined oppositely in the transverse direction so that the upper face and the lower face are each provided with two corner cutting edges at diagonally opposite corners. The longitudinal length of the insert is longer than the transversal length of the insert. The cutting insert can be mounted stably to a small-diametered cutter with a sufficient mounting surface.

摘要： A milling cutter is provided with a cutting insert having improved main cutting edges. The main cutting edges are positioned along both lengthwise edges of a front surface, have a wave shape and are asymmetrical with each other. Main cutting edges positioned along both lengthwise edges of a back surface are rotationally symmetrical by 180 degrees from the main cutting edges of the front surface with respect to a longitudinal central axis of the cutting insert. In the milling cutter, the cutting inserts are alternately mounted in pockets formed on a side surface of the milling cutter so that the concavo-convex portions of the active main cutting edges of the cutting inserts which are adjacent to each other are staggered with respect to each other.

摘要： A cutting insert of the present invention has a body, auxiliary cutting edges of a convex curve shape and main cutting edges. The body has a top surface, a bottom surface, side surfaces connecting the top and bottom surfaces, and corner surfaces connecting the adjacent side surfaces. The auxiliary cutting edges are formed at intersections between the top and bottom surfaces and the side surfaces. The main cutting edges are formed at intersections between the top and bottom surfaces and the corner surfaces. The main cutting edge in the top surface extends from an end of an adjacent auxiliary cutting edge to its center in a direction toward the bottom surface and from the center to an end of another adjacent auxiliary cutting edge in a direction away from the bottom surface.

摘要： The present invention is directed to a cutting tool, comprising: at least one cutting insert; a tool body including a pocket portion to which the cutting insert is mounted; a means for fixing the cutting insert to the pocket portion of the tool body; and a screw for finely adjusting the position of the cutting insert fixed to the pocket portion of the tool body. The screw has a head portion, a threaded portion and a portion for connecting the head portion to the threaded portion. The pocket portion has a bottom surface with a screw hole formed thereon into which the threaded portion is fastened. It also has a side wall comprising a surface for closely contacting the head portion of the screw. The head portion of the screw closely contacts and resiliently pressurizes the close contact surface of the pocket portion when the threaded portion is fastened into the screw hole.
