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

FIELD: technological processes.

SUBSTANCE: invention relates to the abrasive tools on a ceramic bundle production and operation, namely, abrasive disks, and can be used in various branches of machine building. Method comprises the tool impregnation in the boiling aqueous solution containing 20–25 g of chromium diiodide per liter of water for t_n=3.2×10^-3ν^1.15a₀/a, min, where ν is the abrasive tool volume in cm³; a_o is the abrasive tool standard porosity from the given abrasive, bundle and composition, %; a is the impregnated abrasive tool porosity, %, with periodic shaking of the container with the chromium diiodide aqueous solution and the tool, and the tool convective drying during its rotation with a speed of 0.3–0.5 s^-1 within 1.5–2 hours at a temperature of 40–50 °C, wherein, capacity with the boiling aqueous solution and the tool periodic shaking is carried out with a frequency of ƒ and amplitude A, equal to ƒ=8.24×10^-4ν^0.95d₃^0.68a₀/a, Hz; A=2.81×10^-5ν^0.83d₃^1.24a₀/a, mm, where d_s is the abrasive grains in the tool main fraction average size, microns, and performed at equal intervals of time t_pt, matching the shaking duration t_t and taken equal to t_t=t_pt=0.1t_p.

EFFECT: invention allows to increase the tool running time between resharpening, reduce the tool wear rate and improve the parts machined surfaces surface layer quality.
