Embodiment Construction

[0035] The technical scheme of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0036] A composite diamond cutter head, including a metal matrix and several diamond particles, each diamond particle is coated with a layer of tungsten on the outside, the outside of the tungsten layer is coated with a layer of nickel, and the outermost layer is coated with each diamond particle of the nickel layer Inlaid in the metal body. Wherein, each diamond particle is evenly or randomly inlaid in the metal matrix.

[0037] Correspondingly, its preparation method comprises the following steps:

[0038] Step 1. Plating tungsten powder on the surface of diamond particles to form a layer of tungsten layer; or, discharge the mixed powder of dia...

Abstract

The invention discloses a composite diamond tool bit, a manufacturing method of the composite diamond tool bit, a diamond saw blade and a manufacturing method of the diamond saw blade. The diamond sawblade comprises a disc-shape base, wherein a shaft hole is formed in the center of the base; a plurality of composite diamond tool bits are uniformly arranged along the periphery of the base; chip removal grooves are formed between the composite diamond tool bits; each composite diamond tool bit comprises a metal matrix and a plurality of diamond particles; the outside of each diamond particle iscoated with a tungsten layer; the outside of each tungsten layer is coated with a nickel layer; and each diamond particle coated with the nickel layer at the outermost layer is inlayed in the metal matrix. The tungsten layers and the nickel layers improve the interface bonding between the diamond particles and the metal matrixes so as to increase the utilization rate of the diamond particles in the diamond saw blade, therefore, the cutting efficiency of the diamond saw blade is improved, the service life of the diamond saw blade is prolonged, and it is ensured that the diamond particles are sintered firmly in the metal matrixes and are not prone to falling off.

Description

technical field [0001] The invention relates to a composite diamond cutter head and a preparation method thereof, a diamond saw blade and a preparation method thereof. Background technique [0002] Diamond saw blade is a cutting tool, which is widely used in the processing of hard and brittle materials such as concrete, refractory materials, stone, ceramics, etc. Diamond saw blade is mainly composed of two parts: the base body and the cutter head. Among them, the matrix is ​​the main supporting part of the bonded cutter head, and the cutter head is the part that cuts during use. The reason why the cutter head can cut is because it contains diamond particles, and the diamond particles are made of metal matrix. Wrapped in the cutter head, it frictionally cuts the processed object in the cutter head, and the cutter head will be continuously consumed during use. [0003] The performance of the saw blade not only depends on the performance of the selected diamond and the metal m...
