METHOD OF ABRASIVE TOOL IMPREGNATION Russian patent published in 2009 - IPC B24D3/34 

FIELD: mechanics, production processes.

SUBSTANCE: sulfur structure stabiliser additive is introduced into impregnation chamber containing sulfur melt, the additive amount making 2 to 5 wt %. Abrasive tool is dipped into the chamber. The tool impregnated, the chamber melt temperature is increased to 180 to 190°C and kept up for 20 to 30 min.
