Abstract
A dressing apparatus comprises at least two electrode pieces each having an arcuate inner surface and being arranged around a grinding stone to define a gap therebetween. A gap adjusting mechanism adjusts the gap between the arcuate inner surface of each of the electrodes and the grinding stone and maintains the gap between the arcuate inner surface of each electrode and the grinding stone equal to each other.
Claims17
A dressing apparatus which performs electrolytic dressing on a circular grinding stone by applying electricity to a grinding fluid supplied between the grinding stone and an electrode having an arcuate inner surface to cause electrolysis which elutes the base material of the grinding stone, the dressing apparatus comprising:
- two or more electrode pieces each having an arcuate inner surface and being arranged around a grinding stone to define a gap therebetween;
- and gap adjusting means for adjusting the gap between the arcuate inner surface of each electrode piece and a surface of the grinding stone and for maintaining the gap between the arcuate inner surface of each electrode piece and a surface of the grinding stone equal to each other.
A dressing apparatus according to claim l;
- wherein the gap adjusting means comprises a guide portion for guiding a sliding movement of the electrode pieces toward the grinding stone, and an adjusting portion separately provided for each of the electrode pieces for adjusting the amount of the sliding movement of the electrode pieces.
