摘要： In an insert clamping mechanism of an indexable grooving tool of the present invention, a shaft portion of a clamping tool has a major axis and a minor axis orthogonal to each other on a center axis thereof in a cross-sectional view perpendicular to the center axis. At least one end portion of the both end portions positioned on the major axis in an outer circumference of the shaft portion is formed into a recessed shape or a linear shape and is disposed not to come into contact with an upper wall and a lower wall of an opening-closing operation slit. Support portions are respectively formed in parts adjacent to the end portions on both sides around the center axis along the shaft portion.

摘要： Die Erfindung betrifft ein Schneidwerkzeug (1) zum radialen und axialen Einstechen und zum seitlichen Verfahren, zum sogenannten Stechdrehen von hauptsächlich metallischen Werkstoffen, mit einem Klemmhalter (2) und einer am Klemmhalter (2) befestigten Schneidkörperunterlage (3) auf der ein Schneidkörper (6) aufliegt, der von einem Spannfinger (4) einer Spannpratze (5) auf die Schneidkörperunterlage (3) gedrückt wird, wobei der Schneidkörper (6) auf der Schneidkörperunterlage (3) über ein Prisma geführt ist.
Damit mit dem Schneidwerkzeug (1) auch seitliche Drehbearbeitungen durchzuführen sind, ohne dass sich der Schneidkörper (6) aus seinem Sitz herausdrehen kann, wird vorgeschlagen, dass der Schneidkörper (6) auf seiner zum Spannfinger (4) gewandten ebenen Oberfläche zwei entgegengesetzt geneigte ebene rechteckige Dachschrägen (7) in der Art eines Sattel- oder Giebeldachs eines Hauses aufweist, die sich ausgehend von der Oberfläche in den Schneidkörper (6) hinein erstrecken und der Spannfinger (4) an seiner zum Schneidkörper (6) gewandten Unterseite zwei an die Dachschrägen (7) angepasste Rampen (8) aufweist.-

摘要： A parting off blade (1) for use in combination with a parting off machine, lathe or the like, which comprises a free front end for cutting a sample (2). The cutoff blade (1) has a shape that at least partially includes an increased thickness in the direction opposite to said free front end. In a first preferred embodiment, a first cutting insert (11) is mounted at the free front end and a second cutting insert (15) is provided behind the first cutting insert (11). The second cutting insert (15) may be mounted such that it is moveable along the blade (1). In another preferred embodiment (see figure 3) a cutting insert (3) having a front part (32) with a width less than a rear part (31) is mounted at the free end of the blade (1).
摘要翻译： 一种用于与切断机器，车床等组合使用的切断刀片（1），其包括用于切割样品（2）的自由前端。 切断刀片（1）的形状至少部分地在与所述自由前端相反的方向上包括增加的厚度。 在第一优选实施例中，第一切削刀片（11）安装在自由前端处并且第二切削刀片（15）设置在第一切削刀片（11）的后面。 第二切削刀片（15）可以被安装成使得它可以沿着刀片（1）移动。 在另一个优选实施例中（参见图3），具有宽度小于后部（31）的前部（32）的切削刀片（3）安装在刀片（1）的自由端处。

摘要： A tool holder has a main body having a holder head extending away from a holder shank in a forward direction, a clamping member non-threadingly retained in the holder head, and a locking member operatively engaging a single abutment surface of the clamping member. The holder head has an insert receiving pocket at a forward end thereof with a pocket support surface substantially facing in an upward direction, and the clamping member is located entirely rearward of the pocket support surface with the abutment surface facing generally upwardly. The tool holder is configured to direct a clamping force towards, and clamp a cutting insert against, the pocket support surface.
