Document Type and Number:
WIPO Patent Application WO/2015/029987
Kind Code:
A1
Abstract:
Provided is a dicing blade capable of cutting even a workpiece composed of a brittle material stably and accurately in a ductile mode without causing cracks and breakage. This dicing blade (26) is attached to a rotatable spindle, and while rotating about the rotation axis of the rotatable spindle, cuts or grooves a flat plate-shaped workpiece to a constant depth of cut while the workpiece is relatively slid. This dicing blade (26) is integrally formed into a disc shape or a ring shape from a diamond sintered compact formed by sintering diamond abrasive grains, and is provided with, at the outer periphery of the dicing blade (26), a cutting edge part (40) in which minute cutting edges formed on the surface of the diamond sintered compact are provided continuously along a circumferential direction.
