Embodiment 1
[0015] Such as figure 1 As shown, the grinding rod provided in this embodiment includes a cylinder 1 mixed with abrasive grains. Those skilled in the art can understand that when the abrasive grains are mixed in the metal mixture, the area covered by the abrasive grains increases, and at the same time The density of the grinding rod is also increased, which improves the holding force of the grinding rod. The grinding rod has a thickness, not just a layer on the surface of the substrate, so the time from a new grinding rod to the grinding of the alloy structure with abrasive grains is greatly increased, and the service life is prolonged.
[0016] A matrix 2 is provided at one end of the cylinder 1 mixed with abrasive grains, and the matrix 2 is fixedly connected with the cylinder 1 mixed with abrasive grains. Those skilled in the art can understand that the provided base 2 is convenient for installation with equipment, for adjusting the length of the grinding rod, and increasi...
Embodiment 2
[0019] Such as figure 1 As shown, in the grinding rod provided in this embodiment, the abrasive grains are diamond grains. Those skilled in the art can understand that diamond particles have high hardness and good wear resistance, and when they are mixed in the metal mixture, the area covered by the abrasive particles is increased, and the holding force of the abrasive particles is improved.
[0020] The cylinder of mixed abrasive particles includes a metal powder mixture. Those skilled in the art can understand that the metal powder mixture utilizes good toughness, which can maintain high grinding force during the grinding and polishing process and is not easy to produce scratches; and the metal powder mixture makes the grinding rod have good hardness, thereby enhancing the grinding force Grain holding power.
[0021] The metal powder mixture includes diamond powder, pore forming agent, carbon powder, tin powder, copper powder, nickel powder, titanium powder, aluminum powde...
Embodiment 3
[0031] Such as figure 1 As shown, in the grinding rod provided in this embodiment, the components of the diamond powder, pore-forming agent, carbon powder, tin powder, copper powder, nickel powder, titanium powder, aluminum powder, and WC powder are 15- 40%, 3-12%, 3-8%, 10-25%, 15-30%, 5-10%, 3-8%, 3-8%, 1-5%.
[0032] The particle size range of the diamond powder is set to be 15 microns to 180 microns. Those skilled in the art can understand that diamond powder with larger particle size is suitable for coarse grinding, while diamond powder with smaller particle size is suitable for fine grinding. Setting the particle size range of diamond powder to 15 microns to 180 microns can take into account both coarse grinding and fine grinding. Grinding demand, increase the utilization efficiency of the grinding rod.
[0033] The difference between the particle size of the pore-forming agent, carbon powder, tin powder, copper powder, nickel powder, titanium powder and aluminum powde...
