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

FIELD: metal working, possibly sharpening of blade type tools. SUBSTANCE: method is realized at using as base geometrical wedge-shape body having flat basic and free surfaces. Method comprises steps of placing (before working) at the same level free surface of base and worked surface of tool blade; grinding together surfaces of base and tool blade. At grinding blade by means of grinding wheel due to elastic and plastic deformation processes contact heat conduction of blade-base butt sharply increases. It provides lowered thermal stress in blade at sharpening it. EFFECT: enhanced quality and efficiency of sharpening blade type tool by means of grinding wheel. 3 dwg, 1 ex
