METHOD FOR ABRASIVE WORKING OF SCREWS BY MEANS OF ANNULAR EMBRACING TOOL Russian patent published in 2001 - IPC

Abstract RU 2170650 C1

FIELD: machine engineering, possibly finish abrasive working of helical surfaces of precision screws of hard-to-grind materials by embracing type grinding. SUBSTANCE: method comprises steps of using annular abrasive wheel embracing worked part and having body in the form of coiled cylindrical spring and abrasive layer on its inner annular surface. Part is subjected to rotation, tool is subjected to reciprocation lengthwise feed motion. Method provides lowered thermal stresses of process and burning free grinding. EFFECT: enhanced quality and efficiency of grinding. 2 cl, 4 dwg, 1 ex
