Document Type and Number:
WIPO Patent Application WO/2016/129136
Kind Code:
A1
Abstract:
[Problem] To improve production rate and increase tool service life by expanding the flow channel area of coolant flow channels formed in a sheet glass tool and ensuring adequate coolant flow. [Solution] A sheet glass tool in which many abrasive grains are anchored in an anchoring layer formed on the tool tip, wherein: a coolant flow channel is formed between a first abrasive grain and a second abrasive grain that are adjacent to each other; and, when viewed in the direction of said coolant flow channel and S is the area of a region enclosed by a first imaginary line that passes through the apex of the first abrasive grain and extends in the thickness direction of the anchoring layer, a second imaginary line that passes through the apex of the second abrasive grain and extends in the thickness direction of the anchoring layer, a third imaginary line that connects the first and second apices, and a fourth imaginary line connecting the bottom of the first abrasive grain to the bottom of the second abrasive grain, and S1 is the area of the region corresponding to the coolant flow channel, S1/S ≥ 0.35 is satisfied.
