摘要： The invention relates to an advancing system for a rotary cutting tool which is driven by a spindle (6) and can be moved in the direction of advancement by means of a regulating device. Said regulating device is driven by an operating spindle (25) which can be driven by means of its own advancing motor (56), synchronously with the spindle (6) or with a speed difference predetermined in relation to said spindle (6). When the operating spindle (25) and spindle (6) are driving the regulating device synchronously no advancement will occur, whereas when a speed difference is set by means of the regulating device, the cutting tool is moved. The operating spindle (25) and the spindle (6) operate at the same speed again after the desired position of the cutting tool has been set.

摘要： An annular thread cutting die head (26) for a power driven threading machine is comprised of an annular support plate (32) supporting a plurality of radially displaceable thread cutting dies (44) spaced apart about the axis (A) of the die hed (26), and an annular cam plate assembly (34) coaxial with and pivotal relative to the support plate (32) to radially displace the cutting dies (44). The cam plate assembly (34) is spring biased to pivot relative to the support plate (32) in the direction to radially retract the cutting dies (44), and is selectively operable relative to the support plate (32) to achieve the cutting of a straight thread or to achieve the cutting of a tapered thread. In connection with the cutting of a tapered thread, receding replacement of the cutting dies (44) is controlled by a unique cam arrangement (132) on the machine carriage (10) engaged by the cam plate assembly (34) under the spring bias and independent of torque imposed on the die head (26) during the threading operation.

摘要： © The invention relates to rotary cutting tools (10) provided with cutting means and mounted in a tool holder (11). A sleeve (17) provided with an eccentric bore is rotatably positioned between the tool holder (11) and the cutting tool (10) for radial adjustment of the cutting means. For purposes of making possible use of cutting tools having centre cutting means the sleeve (17) is rotatable relative to the tool holder (11) about an axis (18) which is radially spaced from the rotational axis (21) of the cutting tool (10).

摘要： Offenbart ist ein Zustellsystem für ein rotierendes Schneidwerkzeug, das von einer Spindel (6) angetrieben wird und über eine Stelleinrichtung in Zustellrichtung verstellbar ist. Die Stelleinrichtung wird von einer Innenspindel (25) angetrieben, die mittels eines eigenen Zustellmotors (56) synchron mit der Spindel (6) oder mit einer vorbestimmten Drehzahldifferenz mit Bezug zur Spindel (6) antreibbar ist. Bei sychronem Antreiben von Betätigungswelle (25) und Spindel (6) erfolgt keine Zustellung, während bei Einstellung einer Drehzahldifferenz über die Stelleinrichtung eine Verstellung des Schneidwerkzeuges erfolgt. Nach Einstellung der Soll-Position des Schneidwerkzeuges werden die Betätigungswelle und die Spindel wieder mit gleicher Drehzahl betrieben.

摘要： The invention relates to a machine tool for machining borings with a large axial length and to a boring tool which is particularly suitable for a machine tool of this type. Said machine tool and boring tool have a boring bar which has at least one tool lip and is supported by means of a steady. Said steady can be connected to said boring bar (28) via a coupling (48) and reduces the radial excursion of said boring bar during the machining process to a minimum.
