DIAMOND ROLL DRESSER FOR GRINDING WHEEL Þ      The grinder will be equipped with a Diamond Roll Dresser.  Þ   The Dresser will have a profile Diamond roll to match the profile of the        component. Þ   The diamond roll gets a drive through a hydraulic motor for its own rotation. Þ        The infeed movement of wheel advance is controlled by the grinder controls.   Normally the Diamond Roll is positioned about 6.00 mm from the diameter.  Þ        When the dresser cycle is activated, the diamond advances of rapid feed    till it is  0.100 mm away from the wheel.   Þ        Normally the dressing amount is 0.010 mm to 0.020 mm for each dress cycle.   The dressing time is between 10 to 15 seconds. In case of normal hydraulic Þ        profile dresser with single point diamond, the dress amount is 0.050 mm each   dress cycle and time is between 3 to 5 minutes. By using the Diamond Roll     Dresser, the dress time and wheel consumption are reduced resulting in   substantial savings.  Þ        The Diamond Roll retracts to its home position of 6 mm from  the newly    dressed wheel diameter.      Þ      The amount dressed is compensated automatically by moving the infeed   regulating wheel slide by predetermined amount after each dress cycle. The   frequency of dressing can be set by the operator.
