    摘要： The invention relates to a chipper knife for chippers of the type comprising a tool (12) which is rotatable on an axis of rotation and is in the form of, for example a drum, disc or truncated conical body, which supports a plurality of such chipper knives. The chipper knife comprises at least one cutting edge (1) which is formed between a flank (2, 2') and a chip guiding surface (4, 4'), and two opposite main surfaces (3, 3') which are adapted to abut against and be retained on the opposite seats (14, 15) of a holder (9, 10) on the tool. At least one main surface (3, 3') of the chipper knife which is located on a wood side of the chipper knife comprises a cross-sectionally convexly bent surface portion (6, 5') which connects to and extends backwards from the flank (2, 2') and the chord of which constitutes at least 20 %, preferably at least 30 % and, most preferably, at least 40 % of the total cross-sectional length of the chipper knife. The invention also relates to a holder for such a chipper knife.

    摘要： Il est proposé un outil pour l'usinage d'alésage, lequel présente, en vue de l'adaptation à différents diamètres d'alésages et tolérances de diamètre, des fils (36) élastiques revêtus de coupants. Lesdits fils sont guidés à leurs extrémités dans des fentes (15) sur le pourtour de la queue (2) de l'outil et serrés, à une longueur déterminée, entre les épaules d'appui (34, 37) prolongeant les fentes, la longueur de serrage et donc le diamètre extérieur des fils pouvant être modifiés à l'état précédant l'introduction dans un alésage à usiner. De cette façon on obtient de multiples possibilités d'utilisation pour l'outil avec une interchangeablilité facile des pièces d'usure et des coûts avantageux de fabrication et de stockage desdites pièces.

    摘要： A cutting tool assembly comprising a tool holder (1) formed with an insert retaining pocket (2) having a pocket base wall (24) and in which is releasably mounted a cutting insert (3) and a shim (4). The cutting insert (3) is of a substantially prismatic shape having an upper surface (8), a lower surface (9) and side relief flank surfaces (10) and at least one cutting corner defined therebetween and presenting at least one cutting edge formed by the intersection of the upper surface and a corresponding number of the side relief surfaces adjacent thereto. The shim (4) generally correspondes in shape and size to the cutting insert (3), the insert and the shim being releasably mounted in the pocket by clamping means so that an upper supporting surface of the shim supports the lower surface of the cutting insert and a lower bearing surface of the shim bears against the pocket base wall, at least a portion of the shim's lower bearing surface being formed, substantially in the region supporting the cutting corner, with a pattern of protrusions adapted to indent the pocket base wall.

    摘要： Proposed is a bore-finishing tool fitted with spring-action wires (36) coated with cutting agent. The ends of the wires are mounted in slots (15) round the circumference of the shaft (2) of the tool and clamped to give a particular wire length between shoulders (34, 37) adjacent to the slits. The length of wire between the gripping points, and hence the outer diameter of the wires before insertion in a bore, can be varied, thus enabling the tool to be adjusted for different bore diameters and bore-diameter tolerances. The tool is therefore suitable for a wide variety of applications, parts subject to wear can be replaced easily, and manufacture and spare-part stock costs are low.

    摘要： A cutting tool having a positioning block (23) inserted between the cutting insert (22) and the insert-receiving seat (21) is disclosed. The disclosed cutting tool demonstrates excellent resistance to damage by severe vibration caused by the milling process. The cutting tool of the present invention comprises (a) a tool body (20) having a recess formed at a forward end thereof and defining an insert-receiving seat (21); (b) a cutting insert (22); (c) a positioning block (23) to be placed between the cutting insert and said insert-receiving seat, having a top and bottom faces and having a hardness thereof which is lower than that of a surface of insert-receiving seat; and (d) clamp means (24, 25) for securing the cutting insert and the positioning block on the insert-receiving seat. The above described positioning block (23) is able to absorb some extend of vibration of the cutting insert during the milling process.
    According to the present invention, there is also provided the cutting tool in which a positioning block (23) has two layers. A hardness of a surface of the insert-receiving seat is higher than that of the first layer but is lower than that of the second layer.
