    Abstract: A broaching tool is manufactured directly from a heat hardened blank of preformed metal by having a grinding wheel of CBN (cubic boron nitride) material cut a broach tooth from the hardened blank by cutting gullets in the blank. The blank is made movable and rotatable relative to the CBN grinding wheel to allow the manufacture of a series of broach teeth forming a broaching tool with various tooth spacings, depths, and angles with respect to the face of the broaching tool.

    Abstract translation: 通过使用CBN（立方氮化硼）材料的砂轮通过切割坯料中的齿槽从硬化的坯料切割拉刀齿，直接从预成型金属的加热硬化坯料制造拉削工具。 坯料相对于CBN砂轮是可移动的和可旋转的，以允许制造一系列拉刀齿，其形成相对于拉削工具的表面具有各种齿间距，深度和角度的拉削工具。

    Abstract: A rotary disc cutter for cutting workpieces, especially gears and the like. The rotary cutter comprises a plurality of cutting blades arranged about the periphery of a rotary disc cutting body with at least a portion of the blades being roughing blades comprising a tip and two sides with each side having first and second side portions. The first side portion along with the tip defining a cutting surface of the blades while the second side portion is relieved such that a clearance is formed between the second side portion and the surface of the workpiece. The clearance being of a dimension to allow the flow of coolant therethrough thereby improving the cooling of the cutting surface and enhancing the flow of chips away form the vicinity of the blades. The invention further includes a substantially reduced number of blade segments. Alternative blade tip configurations are also disclosed.

    Abstract translation: 一种用于切割工件，特别是齿轮等的旋转盘式切割机。 旋转切割机包括围绕旋转盘切割体的周边布置的多个切割刀片，其中至少一部分刀片是粗刀片，其包括尖端和两侧，每侧具有第一和第二侧部。 第一侧部分与尖端一起限定叶片的切割表面，同时第二侧部被释放，使得在第二侧部和工件的表面之间形成间隙。 该间隙具有允许冷却剂流过的尺寸，从而改善切割表面的冷却并且增强切屑从叶片附近的流动。 本发明还包括大量减少数量的叶片段。 还公开了替代的刀片尖端配置。

    Abstract: An endodontic instrument for use in a root canal procedure. The instrument is formed from a substantially hollow tube with at least one elongate slotted aperture extending along a portion of a length of the tube. One or more of the edges of the slotted aperture provide cutting surfaces for extirpating material from the walls of a root canal.

    Abstract: A broach which has several cutting elements and a support unit to which the cutting elements are attached is made by cutting the cutting elements through electric-discharge machining, in particular wire-EDM so that the production thereof is less time consuming and less expensive. Moreover, the cutting elements can already be made to final size and final hardness.

    Abstract: A shaping-and-cutting broach comprising cutting and gauging teeth and a shaping element located before the cutting teeth, said shaping element provided with projections on its surface which contacts the machined surface. Owing to said projections each cutting tooth has a continuous cutting edge and this, in turn, increases the strength of the tool as a whole and reduces the cost of its manufacture and operation.
