GLASS PRESS FORMING DIE MACHINING DEVICE BY SINGLE POINT GRINDING AND METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To enable ultra-precision machining by reducing oxidation, etc., of a grinding wheel. SOLUTION: This glass press forming die machining device by single point grinding performs grinding by rotating a grinding wheel 1 like a circular column having a small diameter and using a corner part of the grinding wheel 1 as a grinding point 2 and is provided with an atomizer 6 turning grinding oil into mist using inert gas and an jet nozzle 7 spouting the grinding oil turned into mist by the atomizer 6 to the grinding point 2 of the grinding wheel 1 and/or its vicinity.
