ABSTRACT:
A method is provided for manufacturing a segmented diamond blade. The method includes the steps of placing a core into a mold and pouring a metal mixture into a mold cavity surrounding the core. The metal mixture is cold pressed to the core to form a blade having a continuous outer rim. Thereafter, the core and outer rim are suspended in a free-sintering furnace which is heated to an initial diffusion bonding temperature. The core and outer rim are heated for an initial bonding time period. Thereafter, the furnace is heated to a final diffusion bonding temperature and the core and outer rim are maintained at this temperature for a final diffusion bonding time period. After the blade cools, it is placed in a cutting tool and segmented. During segmentation, a plurality of radially aligned notches are cut through the outer rim and a corresponding plurality of gullets are cut in the core. During cutting, an inert gas, such as helium, argon or the like, is blown under high pressure directly onto the cutting point. The present method facilitates diffusion bonding and segmentation by using an optimal combination of metal particles to form the outer rim.
