摘要： A cutting insert having four symmetrically located cutting edges is mounted on a cutting insert holder, which is in turn mounted on a rotary driver. One of the cutting edges projects out from the cutting insert holder. The rotary driver rotates the projecting cutting edge along a circular path. A tube end to be finished is held in contact with projecting cutting edge being colinear with the centerline of the tube. A plurality of cutting insert holders each has a cutting insert mounted thereon with the respective projecting cutting edges being located at varying distances from the axis of rotation. The design of the cutting edges also varies. Tube ends having different radii, wall thicknesses, cross section, or chamfers are finished by successively mounting on the rotary driver the cutting insert holders having projecting cutting edges located the required distances from the axis of rotation and having the appropriate designs.

摘要翻译： 具有四个对称定位的切削刃的切削刀片安装在切削刀片保持器上，切削刀片架又安装在旋转驱动器上。 其中一个切削刃从切削刀片架突出出来。 旋转驱动器沿着圆形路径旋转突出的切割刃。 待完成的管端与与管的中心线共线的突出切削刃保持接触。 多个切削刀片保持器各自具有安装在其上的切削刀片，其中相应的突出切削刃位于与旋转轴线不同的距离处。 刀刃的设计也不同。 具有不同半径，壁厚，横截面或倒角的管端部通过连续地安装在旋转驱动器上而完成，切削刀片保持器具有位于距旋转轴线所需距离并具有适当设计的突出切削刃。
