摘要

Provided is a method for cutting non-alkali plate glass, wherein the non-alkali plate glass has a B2O3 content (C) of 0-8.5 mass% and a plate thickness (T) of 0.05-0.30mm, and using a specific cutter wheel on the surface of the non-alkali plate glass, a cutting line is made by scribing, and tensile stress or bending stress is applied to this cutting line, thereby cutting the non-alkali plate glass. Good cutting results can be achieved using the method for cutting non-alkali plate glass of the present invention.
