Example Embodiment

[0051] Example 1

[0052] The abrasive arrangement device of this embodiment, such as figure 1 , 2 As shown in and 3, it includes a vacuum pump 1 and a funnel-shaped suction cup 2. The small opening 5 of the suction cup 2 communicates with the vacuum pump 1 through a pipeline 3, and the large opening end 4 of the suction cup 2 is covered with a porous thin layer 6. The porous thin layer 6 is a metal wire mesh; the funnel-shaped suction cup 2 is filled with a transition layer 7 having a porous structure, and the transition layer 7 is used to pass gas and prevent abrasives from being sucked into the vacuum pump 1; the transition layer is a sponge.

[0053] The physical diagram of the abrasive arrangement device of this embodiment is as Figure 4 , 5 Shown. The funnel-shaped suction cup is like a shower structure, and the porous thin layer at the large open end has regular small holes. When in use, the suction cup is used to suck the abrasive in the metal wire mesh by using the sucti...

Example Embodiment

[0055] Example 2

[0056] The polygonal super-hard composite abrasive of this embodiment is filled with abrasive powder into a polygonal groove of a graphite mold, assembled into a composite block, placed in a six-sided roof, and synthesized at 50,000 atmospheres at 1500°C for 10 minutes Triangular shaped abrasive produced.

[0057] Wherein, the abrasive powder includes the following components in mass percentage: 30% cubic boron nitride with a particle size of 0.5-1μm, 50% corundum with a particle size of 10-30μm, and aluminum nitride 10 with a particle size of 10-30μm. %, 10% of aluminum powder with a particle size of 1-2μm. After mixing the above components uniformly, the abrasive powder is obtained.

[0058] The graphite mold used is such as Image 6 As shown, the polygonal groove is triangular. The polygonal groove of the graphite mold adopts an engraving machine (Zhengzhou Kechuang CNC KC-6090 engraving machine, with an accuracy of 0.001mm). After two-dimensional drawing of ...

Abstract

The invention discloses a polygonal superhard abrasive compound and a method for manufacturing an abrasive tool with the same. The polygonal superhard abrasive compound is synthesized through high temperature and high pressure after polygonal grooves of a graphite die are filled with abrasive powder and synthesis blocks are assembled. Due to the fact that the polygonal superhard abrasive compound is the abrasive material which is regular in shape and synthesized through high temperature and high pressure after the polygonal grooves of the graphite die are filled with the abrasive powder and the synthesis blocks are assembled, the hardness is high, and the toughness is good; the size dimension is controllable, the particle size is uniform, and good grinding performance is achieved; the shape is regular, the sharpness of the abrasive material is further improved, the abrasive tool with abrasive material cutting edges evenly distributed in a space can be obtained conveniently, the grinding quality and the grinding effect of the abrasive tool can be improved, and the polygonal superhard abrasive compound and the abrasive tool are suitable for application and popularization.

Description

technical field [0001] The invention belongs to the technical field of superhard abrasives, specifically relates to a polygonal superhard composite abrasive, and also relates to a method for preparing abrasive tools by using the polygonal superhard composite abrasive. Background technique [0002] Abrasives are materials with a certain hardness and a certain grinding ability that can be used for grinding purposes. Generally, they are granular or powdery mineral materials with a certain hardness and toughness. Abrasives are divided into two categories: natural abrasives and artificial abrasives. Natural abrasives include diamond, corundum, garnet, quartz, etc., and artificial abrasives include three series: diamond, carbide, and corundum. In recent years, many natural abrasives have been replaced by artificial abrasives. Abrasives are classified according to hardness into two categories: superabrasives and ordinary abrasives, among which superabrasives are abrasives mainly c...
