Abstract
PURPOSE:To easily form a tapping hole having high joining strength in a hard member by heating mixed powder of Cu powder and Fe powder packed in the hole in the hard member to make sintered body and executing tapped hole machining after diffusing in and joining with the inner wall of the hole in the hard member. CONSTITUTION:In the hole of the hard member of hard line bar, super hard long length blade, etc., the mixed powder compacting of 3-30wt.% Cu powder and the balance Fe powder is packed. Successively, the above mixed powder is heated at 1050-1500 deg.C to make the sintered body, and also the sintered body is diffused in and joined with the inner wall of the hole in the hard member. Next, by executing the tapped hole machining to the sintered dody diffused in and joined with the inner wall of the adove hole, the tapped hole is formed to the hard member.
