摘要

FIELD: machine engineering, possibly finish working of bodies of revolution. ^ SUBSTANCE: method comprises steps of imparting rotation and reciprocation motion along axis of worked surface to cylindrical tool; selecting constant speed of reciprocation motion of cylindrical tool; continuously changing revolution number of tool rotation by increasing it during working period according to condition Vrev = (0.8 - 1.2)Vrec where Vrev - revolution number of cylindrical tool; Vrec - speed of reciprocation motion of cylindrical tool. In the result working traces of passes are not coincided one to other and angle of motion direction of abrasive grain changes that increases wear resistance of tool. ^ EFFECT: enhanced efficiency of working, increased wear resistance of tool. ^ 2 dwg, 1 tbl, 3 ex
