    A method of intermittently dressing the ring-shaped surface or active rim of an axially adjustable dished grinding wheel of a gear grinding machine and which active rim acts upon a workpiece. The position of the active rim is controlled and the grinding wheel adjusted such that the ring-shaped surface or active rim is retained at the same location independent of its wear. The active rim is dressed once within a predetermined dressing interval by means of a likewise axially advanced dressing tool. The dressing tool is then advanced if, within the dressing interval, the grinding disk adjustment or compensating feed has dropped below a predetermined total magnitude.

    (54) DEVICE FOR THE EDITION OF THE END OF THE SCREED GRINDING CIRCLE
    10 has the ability to shift in the axial direction. On the Braban 11, ratchet wheels 1.3 and 14 are located, connected by means of pawls 15 and 16 to a drive 17, axial movement, including cylinders 18 and 19, connected to the distributor element 20. The drum 11 is held by the stop 21 by rotation.
    The machine spindle is mounted in the drum 22, which with the help of ratchet wheels 23 and 24, dogs 25 and 26, cylinders 27 and 28 and distribution element 29 can be displaced in the axial direction, allowing the grinding wheel 2 to move, on command from control unit 6.
    The device also has a command device 30 containing a comparator 31 connected by an input to the control unit 6 of the electrocontact mechanism 3 of the machine, a digital indicator 32 connected to the comparator, a setting controller 33 for the dressing cycle duration connected to the clock generator 34, and also a setting unit 35 for the number of compensation cycles and 36 cycles connected to it. The clock generator 34 is connected to the comparator 31 and to the counter 36 cycles, and the cycle counter in turn is connected to the comparator 31 and the digital indicator 32. The output of the comparator 31 is connected to the actuator 17 of the axial movement of the rotary holder 7.
    The device works as follows.
    When the grinding wheel 2 is worn, the probe 4 turns to close the contact 5. As soon as the contact 5 closes, the control unit 6 sends a command to lead the wheel 2 to the distribution element 29, which actuates the cylinder 27. Each lead of the wheel 2 (compensation cycle) is fixed through comparator 31 by digital indicator 32. At the same time, the unit 35 of the number of compensation cycles sets in advance a certain number of compensation cycles, which is memorized by a counter of 36 cycles. In addition, using the setting unit 33, the duration of the dressing cycle is used to set the period of time between revisions, in accordance with which the clock generator 34 outputs pulses to the comparator 31 and to the counter 36 cycles. If within one of the dressing cycle specified by the setting unit 33, the duration of which is determined by the type of grinding wheel and the amount of the stock to be removed from the product, the number of compensation cycles specified by the setting unit 35 is not achieved, the comparator 31 sends a signal to the distribution element 20, thereby the swivel holder 7 is moved axially by means of the cylinder 19 to the grinding wheel 2. In
    This position corrects the grinding wheel. The signal of the comparator 31 resets the digital indicator 32. The magnitude of the signal for the axial movement of the swivel holder 7 topics
    more significant than the difference between the specified and the actual number of compensation cycles within one editing cycle. If the actual value of the compensation cycles exceeds the value specified within the editing cycle, the comparator 31 gives a signal for editing after the end of the editing cycle time. In this case, to ensure the greatest effect, by starting the processing of a new product, you can move the swivel holder 7 to the one set by 33
    the amount that is achieved by switching on the cylinder 18 through the distribution element 20 according to the signal of the comparator 31.
    Thus, by adjusting the amount of the layer removed from the circle during dressing, depending on the intensity of its wear, determined by the number of compensation cycles within a given dressing cycle, an increase in the quality of dressing and a reduction in the grinding wheel consumption is achieved.
