    • A thread-whirling tool is provided to reduce time for processing by setting the radial direction of each cutting edge in individual inserts to be in contact with the side of each insert which is separated from the cutting edges. A thread-whirling tool comprises a through-hole(10), plural inserts radially arranged around a rotation axis(5), and at least one cutter having at least one cutting edge. The outer threads of various shapes are fabricated in a thread-whirling manner from a solid material of a workpiece. Each individual indexable insert is positively and non-positively fitted to a thread-whirling head(1). Each indexalbe insert having an indexable insert surface on a bearing surface(20) of a freely accessible recess(2) is radially orientated between a first side(21) and a second side(22) of the recess, and mounted on a first plane(7) of the thread-whirling head perpendicular to the rotation axis. The distance of the indexable inserts along the periphery of the thread-whirling head is selected so that more than one cutting edges are simultaneously in contact with the workpiece.
    • 提供一种螺纹旋转工具,以通过将各个插入件中的每个切削刃的径向设置为与与切削刃分离的每个刀片的侧面接触来减少加工时间。 螺纹旋转工具包括通孔(10),围绕旋转轴线(5)径向布置的多个插入件和至少一个具有至少一个切削刃的切割器。 各种形状的外螺纹以螺纹旋转的方式由工件的固体材料制成。 每个单独的可转位插入件正向和非正向地配合到螺纹旋转头(1)。 每个具有可转位的插入表面的指状插入件在可自由访问的凹部(2)的支承表面(20)上径向地定位在凹部的第一侧面(21)和第二侧面(22)之间,并安装在第一平面 (7)垂直于旋转轴线的旋转头。 选择可转位刀片沿着螺纹旋转头的周边的距离,使得多于一个的切削刃同时与工件接触。
