Title:
DIAMOND WHEEL AND SCRIBING DEVICE
Document Type and Number:
WIPO Patent Application WO/2004/110712
Kind Code:
A1
Abstract:
A diamond wheel (8) allowed to roll on the surface of a brittle material without slipping and less producing horizontal cracks in the brittle material. The diamond wheel (8) rolls on the surface of the brittle material to form a scribing line thereon. In the diamond wheel, diamond particles (15)...of 1000 to 8000 meshes are held thereto with a bonding agent. Since the diamond particles projected from the binding agent (16) are easily bitten in the brittle material, even if a load more than necessary is not given to the diamond wheel, the diamond wheel can roll on the brittle material without slipping.
