CUTTING EDGE FOR FIBERS

PROBLEM TO BE SOLVED: To provide a cutting edge for fibers, which is hardly worn out at its knife edge, is sufficiently impact resistant at its base substance part, and furthermore, has thermal stresses caused less when the knife edge is welded with the base body part. SOLUTION: This cutting edge is...

description	PROBLEM TO BE SOLVED: To provide a cutting edge for fibers, which is hardly worn out at its knife edge, is sufficiently impact resistant at its base substance part, and furthermore, has thermal stresses caused less when the knife edge is welded with the base body part. SOLUTION: This cutting edge is provided with a knife edge 1a formed out of a sintered hard alloy (WC+10%Co, and harness Hv : 1700) having a thermal expansion coefficient of 57×10 / deg.C in a temperature rang of 25 of 200 deg.C, and with a base substance part 1b formed out of carbon tool steel (SK-5, quench hardness Hv : 500) having a thermal expansion coefficient of 112.5×10 / deg.C in a temperature range of 20 to 200 deg.C by applying quenching and tempering, and the knife edge 1a is joined with the base substance part 1b by way of a nickel alloy layer 1c.
