Abstract

PURPOSE: To subject a work to rough grinding and finishing grinding successively, by using a grinding wheel consisting of a non-dense grindstone of a smaller diameter and a dense grindstone of a larger diameter which are coaxially formed.
CONSTITUTION: A glass plate moving in the direction of an arrow (b) is brought into contact at its side surface with a rotating non-dense grindstone 4 of a smaller diameter to be roughly ground at a side portion 6'. The glass plate is immediately brought into contact at a side portion 6" thereof with a dense grindstone 3 of a larger diameter which is supported coaxially with the grindstone 4, to subject the side portion 6" to finishing grinding.
