The mechanism of blockage of the high quality grinding disc when grinding titanium alloy has the following main points:

(1) During the grinding process of ferroalloy, due to the effect of grinding temperature, TiO2 and Ti2O3 are easily formed. The hardness of this oxide is basically the same as that of corundum high quality grinding disc. The material with the same hardness is easy to be sticky under high temperature and high pressure. The phenomenon.
(2) Oxide Ti2O3 and corundum Al2O3 have the same crystal structure and similar lattice parameters, so there is a good affinity between Al2O3 and Ti2O3:
(3) One of the important mechanisms for the high quality grinding disc to block. The element has large chemical activity and is easy to form a compound with carbon, nitrogen and oxygen. This compound is easy to form a solid solution of aluminum titanate, Al2O7┬ĚTi2O3, which makes the titanium and corundum have a strong bond and forms a new compound.
(4) The thermal expansion coefficient of titanium oxide and corundum is very close, which improves the reliability of adhesion to corundum.

Due to the above reasons, when the titanium alloy is ground by the high quality grinding disc, the chemical bonding phenomenon is easily generated between the sand and the grinding debris, which causes the high quality grinding disc to be clogged. When the abrasive grain edge is covered by the first chemical adhesion layer, the grinding ability is greatly reduced. The subsequent grinding is carried out during the sliding and pressing process between the adhered abrasive chips and the surface to be machined, and the grinding force and the frictional heat are greatly increased. This state of high temperature, high pressure, and high friction force promotes the pressure welding process between the wear debris and the wear debris. The multiple unit wears debris is welded to each other multiple times to form a blockage of the high quality grinding disc. This is the formation mechanism of the adhesive plug.
