Scribing wheel for brittle material and manufacturing method for same, as well as scribing method, scribing apparatus and scribing tool using the same |
摘要 |
A scribing wheel for a brittle material includes a circumferential ridgeline in which two truncated cones have connected bottoms so as to share a rotational axis. Alternating notches and protrusions are formed along the circumference ridgeline. The protrusion are portions of the ridgeline remaining after the ridgeline is notched. The length of the notches is less than that of the protrusions so that a catch on the surface is improved while lowering the high penetrability.
