Abstract

The invention discloses a ceramic bond grinding tool for oriented arrangement of abrasives and a preparation method thereof. The grinding tool is prepared by the method comprising the following steps: 1) the abrasives, a ceramic bond, a dispersing agent and a solvent are taken for mixing a slurry; 2) the obtained slurry is injected in a mold, and is put in a magnetic field with a strength of 1-50 T for magnetizing to obtain magnetized slurry; and 3) the magnetized slurry is dried and demolded to obtain a biscuit; and the biscuit is sintered and cured to obtain the ceramic bond grinding tool. In the ceramic bond grinding tool for oriented arrangement of abrasives, after the slurry is injected in the mold, the slurry is stood in the high-strength magnetic field; under the effect of electromagnetic force, the abrasives rotate to generate oriented arrangement; the ceramic bond grinding tool for oriented arrangement of abrasives is prepared through the oriented arrangement of the abrasives; an effective cutting edge in the grinding of the grinding tool is added; the grinding capacity of the grinding tool is improved; and the grinding surface quality is improved.

Description

technical field [0001] The invention belongs to the technical field of abrasives and abrasives, in particular to a vitrified bonded abrasive with directional arrangement of abrasives, and also relates to a preparation method of vitrified bonded abrasives with oriented arrangement of abrasives. Background technique [0002] Artificial superabrasives, namely cubic boron nitride and diamond, have anisotropic crystal form and irregular shape. Abrasives prepared with superabrasives are superabrasives. The abrasives of the traditional superhard grinding wheel are randomly arranged. When the grinding wheel is grinding, the direction of the cutting edge cannot be guaranteed to be consistent, which greatly reduces the number of effective cutting edges. Therefore, if the cutting edges of the grinding wheel are uniformly arranged radially, the number of effective cutting edges can be greatly increased, thereby improving the grinding ability of the grinding wheel and improving the grind...
