Abstract: A molding apparatus of a glass material according to the present invention is characterized by containing means for holding a glass material and a molding die in contact with each other, means for heating the glass material and the molding die, and means for applying a voltage across the glass material and the molding die, in which press-molding is performed by electrostatic attraction acting between a surface of the glass material and a surface of the molding die. Further, a molded product of a glass material according to the present invention is characterized by including an alkali metal as a component, in which a concentration of the alkali metal is lowered in vicinity of a surface to be molded as compared with that of a glass base material.

Abstract: In order to solve problems involved in micromolding of a glass, according to the present invention, there can be provided a technology for enabling molding of a glass without applying a large load. A molding apparatus of a glass material according to the present invention is characterized by containing means for holding a glass material and a molding die in contact with each other, means for heating the glass material and the molding die, and means for applying a voltage across the glass material and the molding die, in which press-molding is performed by electrostatic attraction acting between a surface of the glass material and a surface of the molding die. Further, a molded product of a glass material according to the present invention is characterized by including an alkali metal as a component, in which a concentration of the alkali metal is lowered in vicinity of a surface to be molded as compared with that of a glass base material.

Abstract: A miniature machine tool for micro-machining is capable of performing on a workpiece at least one conventional mechanical machining operation and another micro-machining operation such as electrochemical machining (ECM), electro deposit machining (EDM), micro-milling or micro-turning or micro-drilling. The machine tool includes a holder in which the workpiece is clamped during all successive machining operations so that the machining operations may be performed in succession without intervening reclamping of the workpiece. This increases dimensional accuracy when micro-machining high-precision components.
