    摘要： The invention relates to a tool for machining sliding surfaces of a bearing shell (30), comprising a rotary drive for driving a drilling spindle (20) that can be rotated about a rotational axis and at least one first cutting cartridge that is mounted on the drilling spindle (20) in order to cut the bearing shell (30) to a certain wall thickness by rotating the drilling spindle (20). The tool is characterised in that the first cutting cartridge can be adjusted by an adjustment means in a direction of adjustment that has a component in the radial direction of the drilling spindle, while the drilling spindle (20) is rotated by the rotary drive. The invention further relates to a bearing shell (30) comprising a deliberately structured sliding surface (31) and to a method for producing a bearing shell (30) comprising a deliberately structured sliding surface (31).

    摘要： To provide a machine tool not only capable of machining an inner surface of a workpiece into a spherical surface but also capable of machining a bearing surface including a flat surface and machining the combination of a spherical surface and a flat surface, and to provide a workpiece inner surface machining method using the machine tool. A machine tool includes: a workpiece holding mechanism 3 holding the workpiece 21; a tool 20 having a supporting member 22 and a cutting tool 23 which is supported to be pivotable about a pivot axis b located on a plane perpendicular to an axis a of the supporting member 22 and has a cutting edge 23a at least at one end; an axial feed mechanism 6a rotating the supporting member 22 about the axis a and moving the supporting member 22 in a direction of the axis a; a pivot driving mechanism 31 pivoting the cutting tool 23 about the pivot axis b; and a machining control mechanism controlling a pivot angle θ of the cutting tool 23 decided by the pivot driving mechanism 31 and a rotation speed and a position in the axis a direction of the supporting member 22 decided by the axial feed mechanism 6a, so as to make a machining point P by the cutting edge 23a move along a desired machining line.

    摘要： The invention concerns a positioning drive for a tool head designed for use in machine tools. The tool head has a main body (12), a tool shaft (16) which extends out longitudinally beyond the main body (12) and which can be coupled to a rotating machine spindle (14), plus a thrust element (18) which can be moved relative to the main body (12) to adjust the position of at least one cutting tool or cutting-tool carrier. Also located in the main body is an electric motor (24) which can be coupled to the thrust element (18), plus a power-supply unit (26) for the motor. In to ensure a compact design with a high-performance motor, a hollow shaft (50) is mounted in the main body (12) so that it can rotate about an axis concentric with the axis of motion (52) of the thrust element (18), the hollow shaft (50) having an internal thread which engages in an external thread (42) around the thrust element (18), plus a toothed ring (62), concentric with the external thread (42) and designed to engage in at least one gearwheel (70) mounted on the drive shaft (68) of the motor.

    摘要： An apparatus for machining a hole in a work piece includes a spindle motor (12) that is rotatable about a principal axis (54). The spindle motor includes a tool holder (22) having a tool axis (26) substantially parallel to the principal axis (54). The tool holder (22) is rotatable about the tool axis. An axial actuator (16) is configured for moving the spindle motor (12) in an axial feed direction substantially parallel to each of the principal axis (54) and the tool axis (26). A radial actuator (14) is configured for adjusting a radial distance between the principal axis (54) and the tool axis (26).
