SEGMENT FOR PREVENTING UNDERCUT

摘要

PURPOSE: A segment for preventing an undercut to reduce a production cost as improving a performance of a saw blade as increasing a tenacity. CONSTITUTION: Diamond particle is distributed as one layer only on a surface without containing the diamond particle in a segment. The diamond segment is produced by baking by mixing/forming metal powder with the diamond particle(15). A tenacity of the segment is decreased and the segment becomes brittle to be broken easily as the containment of the diamond increases because the diamond powder performs as a hetero-material. According to the fact, filling in the segment with the metal powder layer(16) is to increase the tenacity and distributing the surface with the diamond particle(15) is to prevent a breakage or exclusion of the segment for preventing undercut by shock. And also not using diamond in the segment reduces a cost.
