摘要： An apparatus for polishing the relief surface of a specially shaped cutting edge employed in an end mill, the apparatus including a polishing unit (30) having a rotary grinding wheel (31), a model guide (61) disposed at the lower portion thereof with the same guide surface (61a) as the polishing surface of the grinding wheel (31), a cutter support (40), a model support (50) for supporting a model (B1) in parallel with the axis of a cutter (A), and a drive unit (70) for moving both the supports (40), (50) in unison toward the grinding wheel (31) and the model guide (61). The model (B1) has the same outer peripheral surface as the rotary profile of the cutter, whereby a groove (C) is cut so as to form a model line (C1) corresponding to the cutting edge as predetermined. The relief surfaces (24), (25) are accurately and easily polished by copying the model (B1) while making the model (B1) contact the guide surface (61a) along the model line (C1) and by turning both in unison while making the cutter (A) contact a polishing surface (31a).

摘要： A drill has a pair of cutting edges (2) formed at one end of a shank and arranged symmetrically, each cutting edge comprising a central edge portion (21) and an outer edge portion (22), the central and outer edge portions each extend substantially straight and join each other at an obtuse angle when seen from below. The central edge portion is formed with a cutting face (25) substantially parallel to the drill axis. A land portion (24) of the two edge portions has a top face (4) joined to the cutting face (25) of the central edge portion and curved to give a large area to the cutting face. The invention also includes a method of grinding the drill with the outer periphery and a side surface of a rotary grinder, and a drill grinding apparatus for practising the method comprising a holding frame for reciprocating the drill axially, means for rotating the drill, and position changing means for altering the angle between the grinder and the drill.
摘要翻译：钻头具有形成在柄的一端并对称布置的一对切削刃（2），每个切削刃包括中心边缘部分（21）和外边缘部分（22），中心和外边缘部分各自延伸基本上是直的，从下方观察时以钝角相互连接。中心边缘部分形成有基本上平行于钻头轴线的切割面（25）。两个边缘部分的接地部分（24）具有接合到中心边缘部分的切割面（25）的顶面（4），并弯曲成使切割面面积大。本发明还包括一种用旋转研磨机的外周和侧面研磨钻头的方法，以及用于实施该方法的钻削研磨装置，该钻头研磨装置包括用于使钻头轴向往复运动的夹持框架，用于旋转钻头的装置和位置用于改变研磨机和钻头之间的角度的改变装置。

摘要： Apparatus for grinding drills with curved cutting edges comprises a chuck (60) for holding a drill (1). The chuck (60) is mounted on a shaft (6) journalled in a movable frame (4) slidable in an oblique guide (3). A cam (7) on the shaft (6) cooperates with a follower roller (72) mounted on a fixed frame (5) to guide the cutting edge (11 ) of the drill (1) against a grinder (2).
