Abstract RU 2155197 C1

FIELD: abrasive materials. SUBSTANCE: invention relates to manufacturing abrasive tools with polymer binders widely employed for finishing treatments, in particular for polishing mechanical and instrumentation engineering products. Method of invention, including mixing abrasive filler with polystyrene- based polymer filler, molding tools according to specified shape and size, baking, cooling, and dislodging, is distinguished by preliminarily preparing polymer binder by stirring suspension of polystyrene beads with medicinal Vaseline oil. Abrasive filler heated to 220-250 C is then mixed with polymer binder and agglomeration of abrasive tool is accomplished at 120 to 220 C. EFFECT: improved physico-chemical and operational characteristics of tools. 1 tbl, 6 ex
