Abstract
PURPOSE: To effect a rapid and accurate grinding of a glass by a method wherein some rotary grindstones having different diameters and different substances are rotated about a common central axis slightly inclined and the glass on a moving device is contacted with and passed by the grindstones.
CONSTITUTION: Common central axis a of the concentric rotary grindstones 4, 5 is intersected with a moving direction b of a work 3 in such a direction as being inclined slightly from the orthogonal direction with respect to the moving direction of the work 3, and the grindstones 4, 5 are supported on a moving frame. The side surface of the work 3 is contacted with and passed by a front surface of the grindstones 4, 5, a side surface 3' of the sheet glass 3 is medium finished by the small diameter grindstone 5 and then the side surface 3" is contacted with the large diameter grindstone 4 to finish a final grinding.
