BONDING METHOD OF DIAMOND

摘要

In the diamond bite, an insert with projected diamond tip is fixed in the insert hole of a defined depth, formed at upside of bite edge, by bolt and adhesive. A method for attaching the diamond tip to the end portion of insert comprises interposing an active silver solder between the diamond tip and the insert, and heating at 700-850 deg.C in a vacuum container of 10-5 torr. The solder is composed of 59-65 wt.% Ag, 12.5 wt.% In, 27.25-35.25 wt.% Cu and 0.25-1.75 wt.% Ti. The bite has a high strength and excellent workability.
