    摘要: The invention relates to a shaft tool for machine tools, comprising a shaft (10), a tool head disposed at a shaft end and equipped with at least one cutting element (12), and comprising a coupling element (16) disposed at the other shaft end for direct or indirect connection to a machine spindle. A unique feature of the invention is that the shaft (10) comprises a peripheral groove (18) that extends along the circumference of the shaft and is open radially, and at least one spreading element (20) that engages in the peripheral groove and can be radially adjusted therein, resulting in the exertion of spreading and bending forced onto the groove flanks (24’, 24’’). The peripheral groove (18) is filled with a filler material (32) at least in the area of the spreading element (20), the filler material having both a sealing function against contaminants and a damping function. The filler material (32) also acts as a rotation prevention for the spreading elements.

    摘要: First and second bore blade portions (4a, 4b) are provided on the outer periphery of a rotary shaft (1) at intervals in the circumferential direction with a rotation axis (1a) as the center. A first bore blade portion (4a) has a continuous blade (6) and a second bore blade portion (4b) has a discontinuous blade (8) having protruding blade edges (10) and indented blade edges (11), which are alternately provided. The distance (R10) in the radial direction of the protruding blade edges (10) is set so as to be greater than or equal to the distance (R7) in the radial direction of a continuous blade (6), and the distance (R11) in the radial direction of indented blade edges (11) is set so as to be smaller than the distance (R7) in the radial direction of the continuous blade (6). Accordingly, the cutting resistance of the bore cutter can be reduced (Fig. 2).

    摘要: Ein rotierend antreibbares Fräswerkzeug weist einen zylindrischen Trägerkörper (10) auf, der am Umfang mit einer Vielzahl von Schneidkörpern (12) aus einem Schneidstoff härter als Hartmetall bestückt ist. Die Schneidkörper (12) sind plattenförmig ausgebildet und jeweils derart ausgebildet und angeordnet, daß der vorauseilende Bereich der radial äußeren Umfangskante die Schneidkante, die angrenzende Seitenfläche (15) die Spanfläche mit einem negativen Spanwinkel und die der Grundfläche gegenüberliegende Oberfläche (17) die Freifläche bilden. Zu diesem Zweck sind die Schneidkörper (12) mit ihrer Grundfläche jeweils auf der Endfläche von mit demjenigen Winkel zur kürzesten Verbindungslinie zwischen dem Mittelpunkt der Endfläche und der Mittellängsachse des Trägerkörpers (10) ausgerichteten Sackbohrungen (30) in dessen Umfangsfläche befestigt, daß die an die Schneidkante angrenzende Seitenfläche (15) den vorbestimmten Spanwinkel bildet.

    摘要: The invention relates to an end mill comprising a tool body (10) having a generally cylindrical column shape. The tool body (10) comprises a plurality of grooves (15, 115) formed in a spiral shape around the axis thereof on the circumferential surface (14) thereof. Each of the grooves (15, 115) has a plurality of cutting insert elements (17, 117) disposed on a wall thereof so that the cutting edge (21, 121) of the cutting insert elements (17, 117) faces toward the external circumference of the tool body (10). A first group of grooves (15) has a first number of the cutting insert elements (17) disposed therein with a first spacing along the wall (15a) in the direction of the spirally formed grooves. A second group of grooves (115) including the remainder of the spirally formed grooves, wherein each of the second group of grooves (115) has a second number of the cutting insert elements (117) disposed therein with a second spacing along the wall (115a) in the direction of the spirally formed grooves.
