    • A machine having a drive motor which rotates a tapered workpiece having peripheral cutting spirals through constant velocity universal joints and which simultaneously moves the workpiece longitudinally to generate a lead which corresponds to the lead of the cutting spirals. The machine has an upper table which can be horizontally tilted to compensate for the taper of the workpiece so that a rotating grinder wheel, fixed in a predetermined vertical position above the workpiece, frictionally engages and grinds each cutting spiral as the workpiece is driven. A lead start selector permits workpiece to be turned relative to the grinder wheel before a grinding operation so that the start of any cutting spiral is engaged by the grinding wheel.
    • 一种具有驱动马达的机器,该驱动马达通过等速万向接头旋转具有外围切割螺旋的锥形工件,并同时沿纵向移动工件以产生对应于切割螺旋的引线的引线。 机器具有可以水平倾斜以补偿工件的锥度的上台,使得固定在工件上方的预定垂直位置的旋转研磨轮在工件被驱动时摩擦地接合和研磨每个切割螺旋。 引导启动选择器允许工件在研磨操作之前相对于研磨轮转动,使得任何切割螺旋的开始被砂轮接合。

    • A form tap includes a shank having a shank length and a thread portion that extends along at least a portion of the shank length. The thread portion includes a finishing portion and a chamfer portion. Each of the finishing portion and the chamfer portion include a plurality of threads and each thread has a crest and a root. The plurality of threads of both the finishing portion and the chamfer portion are spaced apart at a constant pitch, such that a crest-to-crest distance between adjacent threads remains constant along the entire thread portion.
    • 形状分接头包括具有柄部长度的柄部和沿柄长度的至少一部分延伸的螺纹部分。 螺纹部分包括精加工部分和倒角部分。 每个精加工部分和倒角部分包括多个螺纹,并且每个螺纹具有顶部和根部。 精加工部分和倒角部分的多个螺纹以恒定间距间隔开,使得相邻螺纹之间的波峰间距保持沿整个螺纹部分恒定。
