A cutter head with evenly distributed diamonds and its preparation process

Abstract

The invention discloses a cutter head with evenly distributed diamonds, which is characterized in that it includes a cutter head body, the cutter head body is formed by pressing multi-layer sheets, and each layer of sheet is made of diamond spheroidized particles and metal powder balls The diamond spheroidized particles are fully mixed and cold-pressed according to the comprehensive ratio; 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; the metal powder spheroids The spheroidized particles are directly spheroidized by metal powder; the size of the spheroidized particles of the metal powder is 15-120 meshes; The invention can prevent the diamond segregation of the cutter teeth, avoid the instability of the use of the diamond tool, keep the cutting speed consistent, and provide users with a good cutting feel.

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...

AI Technical Summary

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.
