Heat chamfering apparatus and method

Abstract

A heat chamfering apparatus. A support unit supports a glass panel. A heat chamfering unit heat-chamfers an edge of the glass panel by applying thermal shock thereto. The support unit includes a contact support portion supporting the glass panel while in contact with the glass panel and a base portion configured to support the contact support portion. The contact support portion is formed from a first material. The base portion is formed from a second material. The first material has a smaller change in temperature due to lower thermal conductivity and a smaller change in size at high temperature due to a smaller coefficient of thermal expansion while being more ductile due to lower hardness, compared to the second material. In a heat chamfering method, a glass panel is located on a support unit, and an edge of the glass panel is heat-chamfered by applying thermal shock thereto.
