Problems solved by technology

However, in the above-mentioned diamond tools, the diamonds are randomly distributed on the surface of the cutter body, and the disordered arrangement and irregular distribution of the diamonds cannot fully and effectively utilize the cutting performance of the diamonds. The cutting efficiency of the diamond tools is low, and the utilization rate of the diamonds is low. Caused a waste of diamond resources

Embodiment 1

[0035] The diamond tool of the present embodiment, such as figure 1 , 2 , 3, including a cutter body 5, the cutting surface of the cutter body 5 is provided with a plurality of orderly arranged slits 4, and the slits 4 are arranged in parallel and all run through the front and rear sides of the cutter body 5; The angle between 4 and the bottom plane of the cutter body 5 is 45°, and the width of the slit 4 is 2mm; the distance between the bottom of the slit 4 and the bottom plane of the cutter body 5 is 5mm; the depth of the slit is 5mm; 3 / 4 of the body thickness; diamond particles are brazed and fixed in the slit 4.

[0036] The preparation method of the diamond tool of the present embodiment comprises the following steps:

[0037] 1) Open a slit with a slit width of 2mm on the cutter body by sawing to obtain a slit cutter body;

[0038] 2) After mixing the diamond particles and the brazing material, fill them into the slit of the slitting cutter body obtained in step 1) to...

Embodiment 2

[0041] The diamond cutter of this embodiment is the same as that of Embodiment 1, including a cutter body, and a plurality of orderly arranged slits are provided on the cutting surface of the cutter body, and the slits are arranged in parallel and all run through the front and rear sides of the cutter body; The angle between the slit and the bottom plane of the cutter body is 40°, the width of the slit is 0.5mm, and the distance between the bottom of the slit and the bottom plane of the cutter body is all the same, which is 1.5mm; There are diamond particles.

[0042] The preparation method of the diamond tool of the present embodiment comprises the following steps:

[0043] 1) Open a slit with a slit width of 0.5mm on the cutter body by sawing to obtain a slit cutter body;

[0044] 2) After mixing diamond particles and brazing material, fill them into the slit of the slitting cutter body obtained in step 1) to obtain a semi-finished product; the brazing material is a solder ...

Embodiment 3

[0047] The diamond composite tool of the present embodiment is a diamond saw blade, such as Figure 4 As shown, it includes a disc-shaped saw blade base 1, and the center of the saw blade base 1 is provided with a mounting hole 7 for mounting and matching with the rotating shaft and surrounding the mounting hole for positioning during installation. Positioning holes 3; the peripheral surface of the saw blade base 1 is spaced apart with chip removal grooves 6 running through the upper and lower ends of the saw blade substrate, and the peripheral surface of the saw blade base is welded between two adjacent chip removal grooves 6 for implementation. The diamond cutter 2 described in Example 1; the inclination directions of the slits on the diamond cutter 2 are consistent, clockwise or counterclockwise.

[0048] The preparation method of the diamond composite tool in this embodiment is to weld the diamond tool on the peripheral surface of the saw blade substrate, and the cutting s...

Abstract

The invention discloses a diamond cutter and a preparation method thereof, and a diamond composite cutter. The diamond cutter includes a cutter body, and a plurality of orderly arranged slits are provided on the cutter body. Brazing and fixing a diamond particles. In the diamond cutter of the present invention, a plurality of orderly arranged slits are provided on the cutter body, and diamond particles are brazed and fixed in the slits, and the three-dimensional distribution of the diamond particles in the cutter body is realized by using the plurality of orderly arranged slits , the arrangement of diamond particles on the cutting surface of the tool is more uniform and orderly than the random arrangement of the prior art, which improves the cutting performance and cutting efficiency of the tool, prolongs the service life of the tool, improves wear resistance, and saves raw materials at the same time , reduces the production cost, and avoids the waste of diamond; the diamond tool has high cutting efficiency and long service life, and is suitable for cutting processing of reinforced concrete, stone and other materials.

Description

technical field [0001] The invention belongs to the technical field of cutting tools for non-metal hard and brittle materials, and specifically relates to a diamond tool, and also relates to a preparation method of the diamond tool and a diamond composite tool using the diamond tool. Background technique [0002] Diamond has extremely high hardness, high thermal conductivity and low thermal expansion coefficient. It is the best material for making cutting and grinding tools and is widely used. Diamond tools made of diamond have the advantages of high hardness and wear resistance, low friction coefficient, high elastic modulus, high thermal conductivity, low thermal expansion coefficient, and low affinity with non-ferrous metals, and can be used for non-metallic hard and brittle materials such as Precision machining of graphite, high wear-resistant materials, composite materials, high-silicon aluminum alloys and other tough non-ferrous metal materials. However, diamond itsel...
