  • Patent number: 9600759
    Abstract: A machine tool comprises a first component, for example a dressing spindle (3), and at least one second component, for example a dressing wheel (1), which is removably and/or movably arranged on the first component. The first component has a first antenna coil for a wireless signal transmission, and the second component has a second antenna coil. The two components together delimit a cavity which is completely surrounded by metal. The first antenna coil and the second antenna coil are arranged together in the cavity. This forms a metal-protected radio link (26.1) between the first antenna coil and the second antenna coil, which radio link is protected from harmful external influences.

  • Patent number: 9180574
    Abstract: In a method for producing a base body with hard material particles, an adhesive is first of all applied with a defined film thickness to the entire or parts of the working surface of the tool to be produced. Next, the hard material particles are applied to the regions of the working surface provided with the adhesive for lasting adhesion. Hard material particles are applied evenly by an apparatus and are then transferred to the working surface of the tool to be produced provided with the adhesive, on which they remain adhered before the adhesive has hardened. This method enables rapid coating of the working surface of the tool with a predeterminable uniform number of detached hard material particles per unit of area.

  • Patent number: 8597085
    Abstract: Full profile dressing roll (1) for dressing multi-start grinding worms for the generation grinding of small-module gears, comprising a groove-shaped axial section profile of the outer envelope surface (2), covered with hard material grains, and profile-cut hard-material profile combs (3) embedded in this envelope surface and having a multi-ribbed rack tooth system profile, the profile of which touches the outer envelope surface (2) of the dressing roll (1) only in sections of the axial section profile of the dressing roll (1) which do not participate in the generation of the grinding worm flanks. As a result, the profile sections, highly stressed during the dressing, at the crest and root of the profile grooves (4) are protected from high wear and premature grain loss and the service life of the dressing roll is effectively increased without the inhomogeneity of the flank surface of the dressing roll (1) being disturbed by the profile combs (3).

  • Patent number: 7712219
    Abstract: In a process for the aligning of the tooth spaces of a workpiece with precut teeth, which is set up on the work spindle of a gear finishing machine, the workpiece (1) is brought into no-backlash double flank mesh with a pilot gear (6). The workpiece (1) is rotated, and during this rotation both the angular position of the tooth space centre lines of the pilot gear (6) and the centre distance between the pilot gear (6) and the workpiece (1) are measured. This allows the workpiece (1) to be tested with respect to radial run-out, flank material allowance, helix angle, and any possible irregularities.

  • Patent number: 7452261
    Abstract: A process for monitoring the correct setting of the coolant nozzle (9) of a grinding machine for grinding the tooth flanks of workpieces with premachined teeth. In an automatic test cycle after setting the machine, with the grinding wheel (2) at defined positions relative to the workpiece (3), the alterations in power consumption of the grinding spindle drive when switching on the coolant supply are measured, compared with the desired value ranges specified in the machine control system, and the machining process blocked in the event of measurements being below or above the desired value ranges. In this manner the production of scrap and the occurrence of deflagration of the coolant/lubricant-air mixture in the machine working area, and hence a machine fire, can be effectively prevented.

  • Patent number: 7020972
    Abstract: The invention concerns a process for the aligning of the tooth spaces of workpieces (1) with precut teeth, which are set up for fine machining on the work spindle (2) of a gear finishing machine. In order to avoid the trend related occurrence of out-of-tolerance aligning errors as series production progresses, teach-in cycles are performed on the workpiece machined in the immediately preceding machining cycle, called for automatically after time intervals or machining cycle intervals which are either pre-defined or calculated by the machine control system. By this means any prevailing trend errors are restored to zero.

  • Patent number: 7018278
    Abstract: A detachable fixture of a rotary machining tool (3) on the tool spindle (2) of a machine tool and in particular of a grinding wheel flange (4) on the spindle nose (1) of a grinding spindle (2) is provided with two clamping rings. By means of the Cardanic located clamping rings (10, 13), the clamping force F generated by turning a clamping screw (7) is distributed uniformly on the spindle flange (6). The tool fixture according to the invention permits even large and heavy driven tools with high demands on stiffness and repeatability with respect to radial and axial runout and quality of balance to be changed with little time expenditure.

  • Patent number: 7013744
    Abstract: The invention concerns a device for the non-contact measurement of the position of the teeth (13) of a workpiece (14) with precut teeth on a gear finishing machine. The measuring probe, retractable from the measuring position into a position of rest protected against soiling, is arranged in a holder (5) for radial and axial adjustment relative to the workpiece, the said holder (5) being a kinematic member of a parallelogram linkage (A) and by means of a hydraulic, pneumatic or electromechanical swivel drive (11) is swivellable from stop to stop between measuring position and position of rest in a plane containing the workpiece axis, such that in the advancement action from the lower end position to the top end position motions of the measuring probe (1) tangential to the workpiece circumference are completely avoided. The parallelogram kinematics moreover afford adequate protection against swarf and grinding dust, and lends the device a high stiffness and reliability.
