    • Un alésoir comprend une tige de forage qui tient et fait avancer avec un mouvement pendulaire dans tous les sens une tête porte-lames avec au moins trois lames. Une plaque de guidage (5, 5') perpendiculaire à l'axe de la tige de forage et pourvue d'un évidement central (6) est agencée à l'extrémité libre, cylindrique et creuse de la tige de forage. Cette plaque de guidage (5, 5') soutient et guide dans tous les sens la tête porte-lames (7), étant parallèlement connectée à celle-ci. Cette connexion parallèle se fait par l'intermédiaire d'une surface plane de guidage (8) de la tête porte-lames (7) qui s'appuie sur le côté extérieur de la plaque de guidage (5, 5'), et d'une surface de guidage (40) parallèle à la première et s'appuyant sur le côté intérieur de la plaque de guidage (5, 5') d'une tête de guidage (10, 10') connectée à la tête porte-lames (7) par un collet court et central (9). La longueur du collet (9) correspond à l'épaisseur de la plaque de guidage (5, 5') et le diamètre de l'évidement (6) autour du jeu pendulaire est plus grand que le diamètre du collet (9). La tête de guidage (10, 10') de la tête porte-lames (7) peut être connectée à la tige de forage par une unité mobile d'entraînement (15, 15') de façon à empêcher la rotation de celle-ci. On obtient ainsi une tête porte-lames (7) susceptible d'être déplacée dans tous les sens, d'être aisément et fiablement guidée, connectée de façon facilement amovible à la tige de forage (1).

    • Bei bekannten Reibahlen mit radial verstellbaren Messerplatten ist die Messerplatte in einer Aussparung des Messerkopfes angeordnet und wird mittels zweier Glieder verstellt, die gegen die der Nebenschneide entgegengesetzte Schmalseite der Messerplatte anliegen. Die Messerplatte wird mittels einer Spannpratze gegen die Schulter des Messerkopfes angepresst. Um die radiale Einstellung einer Messerplatte zu vereinfachen, wird gemäß der Erfindung die Messerplatte (3) in einer Aussparung der Spannpratze (2) angeordnet, die schwenkbar am Messerkopf (1) gelagert ist und nur mittels eines einzigen Stellgliedes (5) radial verschwenkt wird. Auf diese Weise werden auch die Schnittkräfte zuverlässig von der Spannpratze (2) bzw. dem Messerkopf (1) aufgenommen.

    • The invention relates to a tool (1) which is used to machine boring surfaces in a precise manner, comprising a blade plate (5) having at least four geometrically defined blades (9, 9'), whereby two are arranged on the front side (11) and two are arranged on the rear side (53) of the blade plate and at least two guide rails (35, 35') whereby one (35) is arranged opposite the blade plate (5) and the other (35') is arranged behind the blade plate (5), when viewed in the direction of rotation, such that it forms an angle of approximately 45° with said blade plate. Said blade plate (5) is inserted into a groove (33) which is formed in the peripheral surface of the tool and forms an insertion angle alpha with an imaginary diametrical line (D1) of the tool. The blade plate (5) comprises, respectively, a cutting surface (49) which is associated with a blade (9, 9') and a free surface (55) which cuts itself and the intersection lines thereof form the cut (9). The free surface (55) forms a free angle ß with an imaginary plane (E) which is perpendicular to the central plane (M) of the blade plate and which cuts the blade. An adjusting device (29), which is used to adjust the projection of the blade plate (5) over the peripheral surface of the tool (1), is provided. Said tool is characterised in that the insertion angle alpha and the free angle ß are adapted to one another such that the equation alpha - ß = approx. 1°, and also an effective free angle of approximately 1 ° is established.

    • A method, machine tool (Fig. 1) and boring bar (12) for machining bores in a series of concentric journals (14) for a camshaft in a cylinder head or block of an engine. The boring bar (12) has an elongate and cylindrical body (72) with a single cutting insert (80) at one end for machining all of the journals (14) one at a time and a plurality of circumferentially spaced and longitudinally extending bearing pads (76) on the body which, when the insert is machining one journal, are received in the previously machined journals to radially constrain and support the boring bar (12). The other end of the bar is received in a chuck (38) or drive spindle of the machine tool which rotates and advances the boring bar (12) through the journals (14) to machine them. Each workpiece (16) is located and clamped in the machine tool (10) with its series of journals (14) to be machined substantially concentric with the axis of rotation of the insert (80) of the boring bar (12). The machine tool alternately rapidly advances and then slowly in-feeds the boring bar (12) through each of the journals at the desired feed rate to machine it. After all the journals (14) are machined, the boring bar (12) is rapidly retracted and withdrawn from the workpiece (16).
