摘要： In a glass cutter wheel where a blade edge is formed on a disk-shaped wheel, grooves having a predetermined shape are formed at a predetermined pitch in a ¼ or smaller or ¾ or smaller blade edge line portion of the entire perimeter of the blade edge. The ratio of the groove portion to the entire perimeter, which largely contributes to a scribing characteristic, is changed such that a desired scribing characteristic can be obtained.
摘要翻译：在叶片边缘形成在盘形轮上的玻璃切割轮中，在叶片边缘的整个周边的1/4或更小或更小的叶片边缘线部分中以预定间距形成具有预定形状的凹槽。改变了槽部分与整个周边的比例，这很大程度上有助于划线特性，使得可以获得期望的划线特性。

摘要： A scribing wheel for a brittle material, comprising: an outer peripheral portion around which a circumference ridgeline is formed, where two truncated cones have connected bottoms so as to share the same rotational axis; and a number of alternating notches and protrusions which are formed in the direction of the circumference along the above described circumference ridgeline, wherein the above described protrusions are formed of portions of the above described circumference ridgeline which remain after the above described circumference ridge line is notched and have a length in the direction of the circumference so that a scribe line is drawn on the above described brittle material substrate and a vertical crack extending from the scribe line in the direction of the thickness of a brittle material substrate is formed when the scribing wheel is rotated in such a state as to be pressed against the above described brittle material substrate, wherein the length of the notches in the direction of the circumference is shorter than the length of the above described protrusions in the direction of the circumference, so that the bite (catch) on the surface of glass is improved, while lowering the high penetrability.
摘要翻译： 1.一种脆性材料用划线轮，其特征在于，包括：外周部，形成有圆周棱线，其中两个截锥体具有连接的底部以共享相同的旋转轴线; 以及沿着上述圆周棱线沿圆周方向形成的多个交替的凹口和凸起，其中上述突起由上述圆周脊线的部分形成，上述圆周脊线在上述圆周脊线被切口之后残留并且在圆周方向上具有长度，使得在上述脆性材料基板上划出划线，并且当划线轮形成从脆性材料基板的厚度方向上从划线延伸的垂直裂纹在上述脆性材料基板上被按压的状态旋转，其中，在圆周方向上的切口长度比上述突起的周长方向的长度短，在玻璃表面的咬（抓）改善，同时降低高透明度亲爱的

摘要： A cutter wheel for forming scribe lines on a brittle plate has a disk with two side planes. The disk has an edge formed at the outer periphery of the disk and a shaft hole formed at the center of the disk for inserting a rotational shaft. Further, at least one groove is formed to extend from a surface of one of the side planes along the shaft hole.
