Abstract:
An apparatus for edge grinding a glazing comprising a grinding wheel, rotatable about an axis, a groove in a circumference of the wheel and first and second orifices arranged on first and second sides of the plane of the groove, which form first and second jets of coolant directed substantially into the groove on first and second trajectories not in the plane of the groove. A corresponding process for edge grinding causes fewer sharp portions and fewer small fractures in the glazing edge than the prior art. A glazing manufactured by the apparatus or the process has higher edge strength than the prior art.
