SHEAR BLADE FOR CUTTING MOLTEN GLASS

摘要

PROBLEM TO BE SOLVED: To prolong the life of a shear blade for cutting molten glass thereby increasing the productivity. SOLUTION: The shear blade for cutting molten glass is formed by laminating the surface of the steel tool blade with the first layer mainly made of titanium nitride 0.1-0.5μm thick, the second layer mainly made of titanium nitride 1.0-5.0μm thick and the third layer mainly made of titanium nitride 1.0-5.0μm thick in turn. In addition, the radius of curvature of the blade edge is adjusted to 0.2-0.25mm to further prolong the blade life.
