摘要： A rotary boring tool adapted to include a locator insert for precision positioning of cutting tips provided on multiple cutting elements or inserts is disclosed. The boring tool comprises a tool body, a plurality of replaceable cutting inserts and an insert locator. The tool body includes a first end having a shank portion and a second end having a plurality of cutter insert supports, a plurality of cutter insert recesses and an insert locator recess. The outside surfaces of the shank portion and the flat portions of the insert locator are jig ground to a 0.000 variance relative to a central rotational axis of the tool body. The insert locator is secured to the tool body at a base surface of the insert locator recess. The cutting inserts are secured to the second end of the tool body so that they contact base surfaces of the cutting insert recesses, first radially and axially extending lateral or side surfaces of the cutting insert supports, and the flat portions of the insert locator. When the cutting inserts are secured in the prescribed manner, the cutting tips lie in a plane that is perpendicular to rotational axis and are spaced the same radial distance from the rotational axis. Being so situated, all cutting tips engage a work piece and thereby facilitate rapid and precise production of a bore having virtually no retraction marks and made to a diametral tolerance of 0.0005 inch.
摘要翻译：公开了一种适于包括用于精确定位设置在多个切割元件或插入件上的切割尖端的定位器插入件的旋转钻孔工具。钻孔工具包括工具主体，多个可替换的切削刀片和刀片定位器。工具主体包括具有柄部分的第一端部和具有多个切削刀片支撑件的多个刀具刀片凹槽和刀片定位器凹部的第二端部。柄部分的外表面和插入定位器的平坦部分相对于工具主体的中心旋转轴线被夹具为0.000。插入定位器在插入定位器凹部的基面处固定到工具主体。切削刀片被固定到刀具主体的第二端，使得它们接触切削刀片凹槽的基面，切削刀片支撑件的第一径向和轴向延伸的侧面或侧表面以及刀片定位器的平坦部分。当切削刀片以规定的方式固定时，切削刀片位于垂直于旋转轴线的平面中并且与旋转轴线间隔相同的径向距离。所有的切割尖端位于这样的位置，并与工件接合，从而有助于快速准确地生产一个实际上没有回缩痕迹的孔，并使其具有0.0005英寸的直径公差。

摘要： A hollow mill tool comprising a shank portion and a plurality of radially spaced and axially extending tool posts integrally formed with and projecting from the shank portion. Each tool post has a longitudinal cutting insert mounting face and each mounting face defines a first plurality of axially extending serrations. A cutting insert is mounted on each mounting face and each insert has a second plurality of axially extending serrations defining a back face and intermeshing with the first plurality of serrations. A threaded fastener extends through a front face of each cutting insert and is received in each of the tool posts to securely hold each cutting insert against its tool post.
摘要翻译：一种中空轧机工具，其包括柄部和多个径向隔开且轴向延伸的工具柱，所述工具柱与所述柄部整体形成并突出。每个工具柱具有纵向切削刀片安装面，每个安装面限定第一多个轴向延伸的锯齿。切削刀片安装在每个安装面上，每个刀片具有限定背面并与第一多个锯齿相啮合的第二多个轴向延伸的锯齿。螺纹紧固件延伸穿过每个切削刀片的前表面，并被接收在每个刀架中，以将每个切削刀片牢固地保持抵靠其刀架。

摘要： A tool interconnect structure includes a spindle adapter, a rotary cutting tool, and a lock mechanism securing the rotary cutting tool to the spindle adapter. The spindle adapter has a face with a short hollow tapered shank at the face. The rotary cutting tool has a face for engaging the spindle adapter face and a tapered recess at the face for cooperating with the tapered shank. The lock mechanism includes a pair of blocks having shoulders at their ends adapted to engage annular grooves within the hollow tapered shank and within the rotary cutting tool. The blocks have threaded apertures therethrough and a screw having oppositely threaded end portions extends through the apertures. Rotation of the screw causes the shoulders to engage with and disengage from the grooves.
摘要翻译：工具互连结构包括主轴适配器，旋转切割工具和将旋转切削工具固定到主轴适配器的锁定机构。主轴适配器的表面在表面有一个短的中空锥形柄。旋转切削工具具有用于接合主轴适配器面的面和在面处的与锥形柄部配合的锥形凹部。锁定机构包括一对在其端部具有适于接合中空锥形柄部内和旋转切削工具内的环形槽的肩部的块体。这些块具有穿过的螺纹孔，并且具有相对螺纹端部的螺钉延伸穿过孔。螺杆的旋转使得肩部与凹槽接合并脱离凹槽。
