Glass cutting blade and machining method thereof

Abstract

The invention discloses a glass cutting blade. A blade body comprises disc surfaces on two sides and a central hole. A first inclined surface and a second inclined surface are separately arranged on two sides of the outer circles of the two disc surfaces, wherein the first inclined surface and the second inclined surface extend outward. The first inclined plane and the second inclined plane are symmetrical inclined planes. The intersection line of the first inclined plane and the second inclined plane forms a peripheral outer cutting edge, and the intersection line of a first groove and a second groove forms an inner cutting edge. The peripheral outer cutting edge and the inner cutting edge form a connected gear-shaped full cutting edge structure. The invention further discloses a machining method of the glass cutting blade. The machining method of the glass cutting blade comprises the steps that blanks are prepared, the center hole is formed by electric spark discharge, an outer circles and the center hole are cut, and the first inclined surface, the second inclined surface and the disc surfaces on two sides are ground according to the center hole positioning reference; and the first groove penetrating through the first inclined surface is cut on the first inclined surface by numerical control laser equipment. According to the glass cutting blade, the full cutting edge structure is achieved, and smooth discharging is achieved. The machining method of the glass cutting blade is high in machining efficiency, and machining quality is effectively improved.

Description

technical field [0001] The invention relates to the technical field of cutting tools, in particular to a glass cutting knife and a processing method thereof. Background technique [0002] With the diversified development of glass products, the fields involved in glass cutting technology are also becoming more and more extensive. A considerable part of the glass to be cut has a very thin thickness and high hardness, and requires high processing precision, so higher requirements are placed on the cutting quality. The existing cutter wheel structure is mainly to process the tooth shape on the outer cutting edge of the circumference, the inner cutting edge is formed by the concave part of the tooth shape, and the full cutting edge is formed by the outer cutting edge and the inner cutting edge of the circumference, but the size of the existing tooth shape concave part is small , making it difficult to discharge materials, and the chip waste is easily blocked on the cutter wheel,...
