PURPOSE: An abrasive device is provided to efficiently grind four corners of a glass plate. CONSTITUTION: A traveling body(B) is installed to move frontward and backward by a traveling device(C). A support(2) is installed to support a glass plate by a suction supporting device. The support installs a circulating portion(1). A first rotating grindstone(3) is installed to bevel two corners in parallel with the traveling direction of the glass plate. A collecting body(D) of the glass plate is installed in front of the traveling body at a certain distance from the traveling body. A circulating base(E) has the suction support and the circulating portion. A second rotating grindstone(28) for cutting the corner of the glass plate is installed near the rotating body. A returning device(F) comprises a traveling member(42) to move leftward and rightward by the traveling device and a supporting device(43) to support the glass plate on the collecting body and the circulating support. A carrying device(G) is installed to carry out the glass plate by supporting through the supporting device. Thereby, the operating efficiency is improved.
