METHOD FOR ABRASIVE TOOLS IMPREGNATION Russian patent published in 2019 - IPC B24D3/34 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to the production of abrasive tools on a ceramic bond and can be used in various branches of engineering. This impregnation method includes the impregnation of the instrument with an aqueous solution of surface-active substances (surfactants) at room temperature for 5–8 minutes and convective drying of the instrument during rotation with a speed of 0.3–0.5 s^-1 and temperature 80–95 °C for 2.5–3.0 hours with continuous shaking. Then, the abrasive tool placed in an aqueous surfactant solution is exposed to an alternating magnetic field of intensity H_V=8–10 MA/m and frequency ƒ=12–15 kHz for 4–6 min, followed by exposure in an aqueous surfactant solution without a magnetic field for 1–2 min.

EFFECT: result is a high contact strength of abrasive grains with a ceramic bond.
