AI Technical Summary

Technical Problem

The efficiency of grinding glass plates is low due to the time-consuming process and poor productivity of conventional grinding apparatuses disposed on transport passages.

Method used

A glass-plate working apparatus with multiple working heads and moving means that allow simultaneous and efficient grinding of both ends of a glass plate, reducing the overall working time and enhancing productivity.

Benefits of technology

The apparatus significantly improves the efficiency of working on glass plate ends, shortening the required working time and increasing productivity by allowing continuous operation from grinding to polishing.
