METHOD FOR BLUNTING SHARP EDGES OF GLASS OBJECTS

摘要

The invention relates to methods for processing glass objects, in particular, to methods of blunting sharp edges of glass objects. A method comprises treating a glass edge with a focused laser beam, while relatively moving the glass object and/or the beam, said treating of the glass edge being carried out with a laser beam having a ring-shaped section, during which the glass edge is heated with the laser beam to a temperature above glass transition temperature, T>Tg. The method provides the creation of tempered glass sections of desired shape and size in the near-edge area due to the provision of thermal stresses in these areas, which cause the formation of a chamfer with rounded or blunt ends on the glass at brittle fracture.
