Problems solved by technology
[0006] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art, and provide a cutter head with evenly distributed diamonds and its preparation process, which can overcome the traditional diamond cutter head, which is easy to cause diamond segregation in the production process, resulting in tire tires on the cutter head. The local diamond concentration in the body is too high, which affects the cutting efficiency of the saw blade. At the same time, the matrix in the produced diamond head has poor holding force on the diamond, and it falls off too quickly during the cutting process, resulting in the problem of short product life.

Embodiment Construction
[0042] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0043] Such as figure 1 As shown, a cutter head 10 with evenly distributed diamonds includes a cutter head body, and the cutter head body is formed by pressing multi-layer sheets, and each layer of sheets is composed of diamond spheroidized particles and metal powder spheroidized particles according to the comprehensive The ratio is fully mixed and cold-pressed;
[0044] The diamond spheroidized particles are formed by wrapping diamond spheroids with a metal powder coating; the size of the diamond spheroidized particles is 30-80 mesh;
[0045] The metal powder spheroidized particles are directly spheroidized metal powder; the size of the metal powder spheroidized particles is 15-120 mesh;
[0046] The diamond spheroidized particles and metal powder spheroidized particles are mixed in a ratio of 10% to 20%.
[0047] Preferably, the metal powder coatin...

The invention discloses a tool bit with uniformly distributed diamond. The tool bit is characterized by comprising a tool bit body, the tool bit is formed by pressing a plurality of layers of sheets,and each layer of sheet is formed by carrying out full mixing and cold pressing on diamond spheroidized particles and metal powder spheroidized particles according to the comprehensive proportion; thediamond spheroidized particles are formed by coating diamond with a metal powder coating; the size of the diamond spheroidized particles ranges from 30 meshes to 80 meshes; the metal powder spheroidized particles are formed by directly spheroidizing the metal powder; the size of the metal powder spheroidized particles ranges from 15 meshes to 120 meshes; and the diamond spheroidized particles andthe metal powder spheroidized particles are mixed according to a ratio of 10% to 20%. According to the tool bit with the uniformly distributed diamond, the diamond segregation of tool teeth can be prevented, the instability of the use of a diamond tool is avoided, moreover, the cutting speed can be kept consistent, and a good cutting hand feeling is provided for a user.
Description
technical field [0001] The invention relates to the application field of diamond, and more specifically refers to a cutter head with evenly distributed diamond and a preparation process thereof. Background technique [0002] Diamond is the hardest substance in nature and is widely used in industrial production, such as diamond tools are often used for building cutting, drilling, road repair, fine polishing, automotive bearing grinding, etc. [0003] Traditional diamond tools are generally made by directly mixing diamond and metal powder, first weighing the material manually, then pressing it into a mold, and finally performing pressureless sintering or vacuum sintering. The production process of traditional diamond tools has the following defects in manufacture and use: [0004] 1. Diamonds are generally irregular in shape and randomly distributed in the cutter head carcass. Uneven distribution or segregation is prone to occur during the molding process of the mixer, result...
