Embodiment 1

[0023] The manufacturing process of the above-mentioned three-dimensional distribution diamond cutter comprises the following steps:

[0024] 1) Take the existing steel saw blade as the saw blade body 201, and process several parallel slits on its surface as the diamond slits 202. The distance between the diamond slits 202 is set according to the needs, and the width is 100% of the particle size of the diamond powder. 2-3 times, and the direction of the diamond kerf 202 is at an angle of 30° to the transverse centerline of the rectangular plane formed after the saw blade body 201 is deployed;

[0025] 2) Take commercially available BNi7 flux paste for brazing diamond, and mix it with 40-100 mesh diamond powder and external reinforcement particles to make composite solder paste, and then fill the composite solder paste into the diamond kerf 202 ,spare;

[0026] In the composite solder paste, the weights of diamond powder and additional reinforcing particles are respectively 10...

Abstract

The invention discloses a three-dimensional distribution diamond cutter and a preparing method thereof and belongs to a cutter for nonmetal hard brittle materials. Firstly, a saw kerf is formed in a saw blade body; then, the saw kerf is filled with composite solder paste for soldering, and diamond powder in the composite solder paste is distributed in a three-dimensional manner and is arranged orderly as well; and next, the saw blade body is soldered to a cutter disk to form the diamond cutter. Due to the fact that the kerf is formed in the saw blade body and the diamond powder is soldered in the kerf, when the solder paste comprising the diamond powder is fused in the soldering process, the kerf with a certain angle can prevent diamond particles in the solder paste from floating upwards so that three-dimensional distribution of diamond can be achieved and the diamond can be arranged orderly as well. Therefore, the prepared diamond cutter is good in sharpness, the service life is prolonged, and the diamond cutter is used for cutting granite, marble, reinforced concrete and other nonmetal cutting hard brittle materials and is also widely applied to cutting airport runway antiskid seams, road and square expansion joints and other nonmetal materials and metal materials

Description

technical field [0001] The invention relates to the cutting field of non-metallic hard and brittle materials such as granite, marble, and reinforced concrete, in particular to a three-dimensional distribution diamond cutter and a manufacturing process thereof. Background technique [0002] The superiority of evenly distributed and orderly arrangement of diamonds on the cutter head is recognized by people, but it is more difficult to implement it on the cutter head. It is possible to realize the uniform distribution and arrangement of diamonds on the cutter head manually, but it is necessary to It is more difficult to achieve industrialization in mass production, so the process and equipment implemented in the production of evenly distributed and orderly arrangement of diamonds is an extremely critical link. [0003] Patent 200920070665.4 provides a cutter head with diamonds arranged in an orderly manner. The cutter head is formed by superimposing and sintering multipl...
