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

FIELD: metal working. SUBSTANCE: unworked adjacent surface of blade is conjugated with basic surface of base made as geometric body of wedge-like form with flat basic and vacant surfaces. During adjustment of machine-tool vacant surface of base is positioned below blade surface subject to working by value hu which is smaller than allowance z removed during sharpening by value of allowance left for final sharpening or finishing. Then grinding operation is performed. The first tool blade surface is ground only, and then after removal of main part of allowance z both surfaces of base and tool are ground together. The method makes it possible to improve quality of blade tool sharpening by grinding wheel, provides for absence of burrs on cutting edge and intensifies process of heat transfer from ground tool blade to base. EFFECT: enhanced efficiency. 3 dwg
