    摘要： A support- and -cutting-tool assembly for use with a lathe for machining elongated flexible rods which, in their initial form, may be cylindrical or polygonal in cross section. The tool assembly includes a carrier adapted to be mounted upon the carriage of a lathe so as to be reciprocated axially thereby toward and away from the collet of the lathe. The carrier is disposed transversely with respect to the path of movement and has a large central opening within which is removably mounted a support block having a passage therethrough alignable with the collet and through which the elongated workpiece projects when gripped by the collet. A cutting bit mounted upon the carrier at the trailing end of the passage is engageable with the workpiece to remove stock therefrom as the workpiece is rotatably driven by the collet and as the carrier and carriage upon which it is mounted are displaced toward the collet. Thus, even though the workpiece is flexible and tends to bow or whip, it may be supported at one end only by the collet and is nevertheless fixedly constrained by the support block during the machining operation at the exact location at which the cutting bit is removing stock therefrom.

    摘要翻译： 一种用于车床的支撑和切割工具组件，用于加工细长的柔性杆，其初始形式可以是圆柱形或多边形横截面。 工具组件包括适于安装在车床的托架上以便沿轴向往复运动的托架，从而朝向和远离车床的夹头。 载体相对于运动路径横向地设置，并且具有大的中心开口，在该中心开口中可拆卸地安装支撑块，该支撑块具有通过其与夹头对准的通道，并且伸长的工件在被夹头夹持时突出。 在通道的后端安装在托架上的切割头可与工件接合，以便当工件由夹头可旋转地驱动时，并且随着其安装的托架和托架朝向夹头移位，从而将其从中移除。 因此，即使工件是柔性的并且倾向于弯曲或鞭状，它也可以仅由夹头支撑在一端，并且在加工操作期间在切削钻头移除的确切位置处由支撑块固定地约束 库存。

    摘要： A C-shaped frame carries a pipe or rod engaging roller at one end. The frame has ways upon which a carriage is slidably disposed and may be moved on the ways by a screw means rotatably journaled in the other end of the frame. The carriage has a pair of pipe engaging rollers which engage the opposite side of the pipe from the first roller. The carriage in turn has ways which slidably carry a cutoff holder. The tool is moved on the carriage by a second screw means which is angularly disposed relative to the first screw means and in interlocking sliding engagement with an angularly disposed cam surface on the cutoff tool holder.

    摘要： A shaving tool holder for use on automatic screw machines or the like. The tool holder is self-adjusting and carries a roller for engaging the work at a location opposite the tool. The roller and tool are supported on a head positioned at one end of a pivoted arm. The arm is spring biased to permit the tool and roller to align with the work.
