Problems solved by technology
[0004] However, the difficulty in the manufacture of such products is that the high temperature during brazing will greatly damage the diamond particles, resulting in a decrease in the strength of the diamond particles and affecting performance; if high vacuum equipment is used for brazing, the equipment cost is high, and the operation mode is not flexible; in addition Achieving an efficient and orderly arrangement of diamonds is one of the goals of all diamond tools

Embodiment Construction
[0028] The technical solutions of the present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.
[0029] The processing steps of the brazed diamond tool manufacturing method of the present invention are as follows:
[0030] 1. Select diamond particles 1 with coating.
[0031] Choose diamond particles 1 with the same size, clean the surface of diamond particles 1, and coat the high temperature resistant layer 2 on the surface of each diamond particle 1; the high temperature resistant layer 2 can adopt Ti (titanium), Cr (chromium), V ( Vanadium), W (tungsten) and other materials, such as figure 1 shown.
[0032] 2. Making diamond pellets 5.
[0033] Each diamond particle 1 prepared with the high temperature resistant layer 2 is wrapped with brazing powder 3 and made into a spherical shape with the same diameter, thereby obtaining diamond pellets 5 with equal diameters; the diameter of the diamond pellets 5 depend...

The invention discloses a manufacturing method for a brazed diamond tool. The method comprises the following processing steps: diamond particles with identical diameters are selected, and the surface of each diamond particle is coated with a high-temperature-resistant layer; the cladding layer of each diamond particle is wrapped by a brazing powder material, diamond spheres are prepared from the diamond particles, and the diameters of the diamond spheres are identical; the surface of a workpiece to be brazed is filled with the diamond spheres, so as to form a single-layer structure of the diamond spheres or a stacked structure with two or more layers of the diamond spheres; in the stacked structure, the diamond spheres on adjacent layers are staggered; the workpiece and the diamond spheres are heated through a high frequency, flame or other methods, so that the brazing powder material is melted and then slowly cooled to form a brazing layer, and the combinations between the workpiece and the diamond particles as well as between the diamond particles are achieved. The method adopting the scheme has the advantages that through the high-temperature-resistant layer and the brazing powder material, the corrosion influence of oxygen in air on the diamond particles can be reduced at a high temperature, so that the effect of brazing in air is achieved, the equipment requirements are reduced, and the manufacturing method is more flexible.
Description
technical field [0001] The invention relates to diamond cutting tool technology, in particular to a method for manufacturing brazed diamond tools, which can be applied to the manufacture of diamond brazed saw blades, drill bits, grinding wheels and other tools, and achieves uniform distribution of diamonds in the tools. Background technique [0002] (High temperature) brazing diamond tools is one of the most popular technologies in diamond tool manufacturing at present. Brazing technology can realize chemical metallurgical bonding of diamond, bonding agent (brazing alloy material) and metal matrix interface, with high bonding strength. [0003] Due to the high bonding strength on the metal matrix interface, only a very thin bond thickness is enough to firmly hold the abrasive grains (diamond particles), and its exposed height can reach 70% to 80%, which is much higher than that of conventional tools. 30%, making full use of abrasives, greatly improving tool life and processi...
