    • The present invention is a rotary head tool that is a self-propelled rotary tool (SPRT) operable for round cutting involving hard turning. The rotary head tool comprises generally a toolholder, a tool that is removably or fixedly connectable to the toolholder, and an insert that that incorporates a cutting edge finable into the tool. The toolholder is formed to hold the tool with the insert therein at a particular angle. Elements of the rotary head tool of the present invention, such as the insert, may be “off the shelf elements and consequently the present invention may be produced at a low cost. Embodiments of the present invention are designed so that the rotary head tool provides economical benefits and affordability for the user and to provide performance benefits of SPRTs.
    • 本发明是一种旋转头工具,其是可操作用于硬切削的圆形切削的自推进旋转工具(SPRT)。 旋转头工具通常包括刀架,可移除地或可固定地连接到刀夹的刀具,以及嵌入件,该刀片结合有可切削成刀具的切削刃。 刀架形成为以特定的角度将刀具保持在其中。 本发明的旋转头工具的诸如插入件的元件可以是“现成的元件”,因此本发明可以以低成本制造。 本发明的实施例被设计成使得旋转头工具为用户提供经济的益处和可承受性并且提供SPRT的性能优点。

    • There is provided a machine tool capable of working a workpiece regardless whether it is gripped by a front spindle or a back spindle while guiding a free end side thereof by one guide bushing (160), is simplify and compacted and suppresses an increase of a number of axes to be controlled. The machine tool comprises the front and back spindles (112) and (122) having one and same axial line and disposed opposite each other and a guide bushing (160) having an axial line identical with the axial line. The guide bushing (160) is disposed between the front and back spindles (112) and (122), is configured so that the guide bushing (160) can guide the workpiece on both ends of the workpiece (W), so that the workpiece gripped either by the front spindle (112) or the back spindle (122) can be inserted, and so that the guide bushing (160) is movable in an axial direction.
    • 提供一种能够对工件进行加工的机床,无论是通过一个引导衬套(160)引导其自由端侧是否被前主轴或后心轴夹持,都被简化和压缩,并且抑制数量的增加 的轴被控制。 该机床包括具有一个相同的轴线并彼此相对设置的前和后主轴(112)和(122)以及具有与轴线相同的轴线的导向套管(160)。 引导衬套(160)设置在前和后主轴(112)和(122)之间,构造成使得引导衬套(160)可以在工件(W)的两端上引导工件,使得工件 可以插入由前心轴(112)或后心轴(122)夹持的导向套管(160),从而可以沿轴向移动。
