Circular saw blade of diamond and method of producing the same

Abstract

The invention discloses a diamond circular saw blade and a maufacturing method thereof. The diamond circular saw blade comprises a cutter body fixed on a basal body, convex ridges arranged on the exterior margin of the basal body. The convex ridges consist of convex wedges and flutes, which are uniformly arranged in turn along the circumference. Both sides of the convex ridges are provided with boss lugs which are distributed unevenly and pits surrounding the same . While the convex ridges are machined, a laser with the control voltage of 500V, the air pressure of 0.5 to 0.8MPa, the laser power density of 10<6> to 10<10>W / cm<2>, the pulse width of 10 to 300 microseconds, the defocusing amount of 0.3 to 1.0 millimeters, the pulse frequency of 100 to 100000 hertz and the laser impacting frequency of 2 to 4Hz shall be adopted for roughing both sides of the convex ridges with laser, thus forming pits. Not only the cutter body is fastened on the basal body, but also the surface area of the convex ridges is increased; the fixing surface of the cutter body and the basal body is increased; the surface of the convex ridges is reinforced; the rigidity and the hardness of the convex ridges are improved, thus improving the connecting firmness and the use reliability between the cutter body and the basal body.

Description

technical field [0001] The invention relates to a metal bonded diamond circular saw blade, in particular to a sintered ultra-thin diamond saw blade, which can be widely used in the cutting of brittle and hard materials, especially in the cutting and grinding of glass. Background technique [0002] At present, most of the cutting tools for brittle and hard materials such as glass use diamond circular saw blades. Since the substrates of these saw blades are generally thicker than 1mm, it is difficult to meet the requirements of material loss and service life. In particular, the strength of the corrugation on the outer edge of the substrate and the degree of bonding and firmness between the substrate and the cutter head are all affected. The matrix itself is also required to have a certain degree of elasticity during processing, which puts forward higher requirements on the processing accuracy, cutting strength and service life of the cutter body.

AI Technical Summary

Problems solved by technology

Chinese patent CN2601807Y discloses an ultra-thin diamond circular saw blade. The base body and the cutter head are sintered together. , there is a pattern on the outer edge of the circular base, which cooperates with the cutter head to increase the connection strength. There is also a thin flange on the base. This technical solution is mainly through the thin flange on the base and the The set pattern achieves the purpose of firmness and durability, but there is no specific technical proposal on the structure of the pattern shape and how to be adjacent to the cutter head to improve the strength of the outer edge of the above-mentioned base

The purpose of this technical solution is to make the cutter body not only connect the cutter body to the base body through the anti-buckle function of the dovetail groove, but also make use of the combination of the dovetail convex wedge and the two sides of the rib and the side wall of the cutter body ring groove, The fixed surface between the cutter body and the substrate is enlarged, so as to realize the firmness of the connection between the cutter body and the substrate, but its disadvantages are: when the dovetail groove is set, the rigidity of the substrate, especially the convex one, is seriously reduced, and there is stress concentration at the bottom of the groove
