Problems solved by technology

The hardness of cemented carbide is small, the performance of the notch produced is not high, and the service life is short, so it is not suitable for cutting flat glass of liquid crystal products
The hardness of polycrystalline (PCD) diamond (micropowder) is equivalent to that of diamond particles, but the processing is difficult and the manufacturing cost is high

Embodiment Construction

[0024] Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] As shown in Figures 1 and 3 of the glass scribing disc of the present invention, the disc 1 is disc-shaped and made of steel. A central hole 12 is provided at the center, and a row of diamond particles 2 are brazed to the tip of the blade portion 11, and the particle size of the diamond particles 2 is #300. The brazing layer 3 is a copper-silver alloy containing at least 3% by weight of titanium.

[0026] The manufacturing method of the aforementioned glass scribing disc is as follows:

[0027] Grind out a "U" shaped groove 13 (as shown in Figure 6) with a diamond grinding wheel on the circular disk 1 (as shown in Figure 5); Fig. 7), the diamond particles 2 are stuck on the viscose 4, and the copper-silver alloy brazing material powder containing at least 3% by weight of titanium is spread in the groove, placed in a vacuum brazing furna...

Abstract

A glass cutter disk is contrived to make scratches on glass. A tip of a blade portion of the disk is soldered with a row of highly-hard diamond particles to make deep scratches with less fractures and scraps, which is particular useful in cutting liquid crystal display panels. The disk is constructed in such a way that the diamonds are glued in place and secured by soldering, which can dramatically reduce the manufacturing cost plus simple and practical processing method.

Description

technical field [0001] The invention relates to a glass scribing cutter, in particular to a glass scribing cutter disc. Background technique [0002] The method of scribing glass with diamond has existed since ancient times, but because diamond is non-metallic, it is difficult to process it into a disc-type tool, which limits its application in industry. At present, the disc-type tool is mainly made of hard alloy such as tungsten carbide or Made of polycrystalline (PCD) diamond (micropowder), etc. When cutting flat glass, especially the flat glass used in liquid crystal products, its hardness is higher than that of ordinary glass, and the cutting precision is required to be higher. This requires a deeper scratch depth to be able to easily and accurately along the scratch. Break the glass with as little chipping and debris as possible at the breaking edge. The hardness of cemented carbide is small, the performance of the notch produced is not high, and the service life is s...
