摘要： A tool changer is used for changing tools in a machine tool. The tool changer has a support structure on which a lifting carriage is guided along a vertical lifting direction. A pivot arm is pivotably mounted to the lifting carriage about a vertical pivot axis. A plurality of tool holders arranged vertically one above the other form a tool magazine. A tool gripper is attached to the pivot arm. The tool gripper grips a tool. The tool is subsequently moved between one of the tool holders and the tool spindle of the machine tool by a combined lifting and pivoting movement of the pivot arm. Optionally, an auxiliary arm pivotably attached to the pivot arm can be used to change a workpiece clamping means of the machine tool.

摘要： A machine tool is designed for the machining of rotary parts with groove-shaped profiles, in particular gears, by a generating method. On the one hand, a Y slide (200) is arranged on a machine bed (100), the Y slide being displaceable along a Y direction and carrying a workpiece spindle (210). The workpiece spindle drives a workpiece (220) to rotate about a workpiece axis (C). On the other hand, a Z slide (300) is arranged on the machine bed. The Z slide is arranged along a Z direction running parallel to a center plane (E1) spanned by the Y direction and the workpiece axis. An X slide (310) is arranged on the Z slide and can be displaced along an X direction relative to the Z slide (300). The X direction is perpendicular to the center plane. A tool spindle (320) is arranged on the X slide, which drives a tool to rotate about a tool axis. The tool spindle can be swiveled relative to the X slide in a swivel plane (E2), which runs parallel to the center plane, about a swivel axis (A).

摘要： A spindle unit for a machine tool for fine-machining workpieces having groove-shaped profiles, has a rotatably mounted spindle shaft (2). The spindle shaft is subdivided in the axial direction (AR), one behind the other, into a fastening portion (A) for fastening a tool (4) or a workpiece to be machined, a first bearing portion (B), a force transmission portion (C), and a second bearing portion (D). A drive unit (5) serves to drive the spindle shaft by way of force transmission onto the force transmission portion. A first and a second bearing point (13, 14) are designed to bear the spindle shaft in the first bearing portion, and a third bearing point (15) serves to mount the spindle shaft on the second bearing portion. The first and the second bearing points each have one or more hydrostatic bearings. The third bearing point has one or more hydrostatic and/or hydrodynamic bearings.

摘要： The invention relates to an electrical machine having a rotor (1), a stator (2) radially surrounding the rotor, and a housing (4) radially surrounding the stator. In order to minimize stresses in the housing and nonetheless decrease the tendency of the stator to torsional vibrations, the stator is connected to the housing at least at one end in a radially and torsionally rigid but axially movable manner, for example, by way of an axially compliant material area. The electrical machine can, in particular, be a motor spindle in a gear finishing machine.

摘要： The invention relates to a device for machining workpieces with precut teeth; having a workpiece support and at least one workpiece spindle arranged on the workpiece support for clamping a workpiece (8). A centering device (20.1) for the workpieces comprises a probe holder (30) with a centering probe (26), which operates in a contactless manner, and a base element (37). The probe holder is connected to the base element such that the probe holder has a variable radial distance to the workpiece spindle axis. The base element is designed as a slide which can be moved relative to the workpiece support. A linear guide for the base element allows a movement of the base element relative to the workpiece support. An adjustment drive for the centering device can be arranged above the centering device on a backrest of the workpiece support.
