METHOD FOR SHARPENING CUTTING BLADE OF TOOL Russian patent published in 2001 - IPC

FIELD: metal working, possibly sharpening blade type tools. SUBSTANCE: method comprises steps of matching non-worked adjacent surface of blade with basic surface of base in the form of geometrical wedge shape body having flat basic and free surfaces; at adjusting machine tool, placing free surface of base lower than worked surface of blade by value equal to admission value for working; filling blade-base butt with heat conductive lubricant and grinding surface of tool blade until contact of grinding wheel with free surface of base. Blade-base butt is filled with heat conductive lubricant and it provides its high contact heat conduction and lowered thermal stress in blade at grinding. EFFECT: enhanced quality and efficiency of sharpening blade tool by means of grinding wheel. 3 dwg
