ABSTRACT:
The present invention relates to a method of discovering optimal conditions such as the rotational speed ratio of an abrasive cloth and a dresser, to improve the flatness of the abrasive cloth after it has been dressed. A narrow annular dresser having an inner diameter of at least the width of a wide annular utilization region of the abrasive cloth is pressed while rotating against the abrasive cloth which is fixed onto a turn table. A rotational motion is imparted to the abrasive cloth in the same direction as the rotation of the dresser and at a predetermined rotational speed. The abrasive cloth is dressed thereby in such a manner that there is a uniform distribution of distances through which the grindstone slides over various points within the utilization region of the abrasive cloth.
