Abstract: In a method of monitoring a condition of a machine tool (1) having a plurality of machine axes, at least a part of the machine axes is systematically actuated in a test cycle, and associated condition data are obtained by measurements. On this basis, EOL data correlating with a noise behavior of a gear train comprising a workpiece machined by the gear cutting machine are predicted. Disclosed is also the reverse direction in which condition data are predicted from EOL data.

Abstract: A gripping device having a holder and two gripper units. Each of the gripper units has a base body and two base jaws. The base jaws can be moved synchronously in opposite directions relative to the respective base body. The gripper units are arranged side by side on the holder so that the base jaws of both gripper units can be moved parallel to a common gripper plane. The gripping device is designed as a single gripper in that only a first gripper finger is attached to each of the two outer base jaws. It can very easily be converted to a double gripper by attaching two further gripper fingers to the inner base jaws, or by removing the first gripper fingers and attaching a second gripper finger to each of the four base jaws.

Abstract: A method for automatic process monitoring during continuous generating grinding of pre-toothed workpieces, which permit early detection of grinding wheel breakouts. A generating grinding machine is used to machine multiple workpieces by clamping them onto at least one workpiece spindle and successively moving them into generating engagement with a grinding wheel. At least one measured variable is monitored during the machining to indicate if a grinding wheel breakout exists. If a grinding wheel breakout is indicated, the grinding wheel is examined automatically by moving a dressing tool over the tip region of the grinding wheel and generating a contact signal. A breakout is determined by analyzing the contact signal and, if present, the grinding wheel is dressed as often as necessary in order to eliminate the grinding wheel breakout. Alternatively, the checking of the grinding wheel is carried out directly at the first dressing stroke.

Abstract: 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.

Abstract: 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.

Abstract: Method for reinforcing a grinding wheel, preferably for grinding gears. By means of at least one plastic that is poured in, both a ring lining a bore of the grinding wheel and a reinforcing layer are formed in the grinding wheel pores. The plastic that is poured in preferably consists of a potting compound, used in the raw state, made of a 2-component polyurethane system. In order to produce the reinforcement, the grinding wheel is set rotating, i.e., rotated, and, at the same time, a specific quantity of potting compound is poured into the bore. An increase in the explosion speed during operation of the grinding wheel is thereby made possible.

Abstract: Disclosed is a method for dressing a single- or multi-thread grinding worm (34) in which a main rolling movement between the grinding worm and a gear-like dressing tool (90) is brought about. In order to create flank modifications on the grinding worm, an additional relative movement is superimposed on the main rolling movement. In addition, an auxiliary drive specifically designed for such a method, a correspondingly designed machine tool and a dressing tool for carrying out the method are disclosed.

Abstract: A method for collision checking of a machining process is disclosed. A process-specific cycle is provided for the machining process. Multiple machining components are moved relative to one another with at least one machine axis on a machine tool. The machining components have at least one workpiece and one tool. The workpiece rotates about a workpiece axis and the tool rotates about a tool axis. At least one checking position is identified and corresponds to a relative position of the machining components set with the at least one machine axis. In order to check a respective checking position for collisions, a substitute machining component is used during the reproducing, which is a replica of the corresponding machining component.
