Abstract
A glass product machining apparatus comprises a grindstone rotatable around an axis by means of a motor, moving table movable under the grindstone in the cross direction of the grindstone, frame for supporting the grindstone for up-and-down motion, lift, guides, supporting arms, pressure cylinder supported on the frame, and dressing machine for dressing or truing the grindstone. The pressure cylinder serves to apply a fixed elastic load to the grindstone as the grindstone shifts its position upward. A glass panel is located on the moving table. The panel moves together with the table. When the panel passes under the grindstone, an outer peripheral surface of the grindstone is brought into contact with the surface of the panel with a fixed force of pressure by the pressure cylinder. The grindstone relatively moves along the curved surface of the panel as it grinds the panel surface.
