摘要:
Bei einem spanabhebenden Werkzeug, insbesondere Stechwerkzeug mit einer gabelartig geschlitzten Halterplatte (1) zum Einklemmen eines Schneideinsatzes (5) ist der Klemmschlitz (2) so ausgebildet, daß die Klemmbacken (3,4) der Halterplatte (1) den Schneideinsatz (5) mit einer vorgegebenen Klemmspannung haltern. Der Schneideinsatz (5) und/oder der obere Klemmbacken (4) sind mit einem Einschubbegrenzungs-Anschlag (25) versehen, so daß der Schnittdruck zu einer proportionalen Erhöhung der Klemmspannung führt.
摘要:
The invention relates to a cutting tool that is intended above all for tube cutting machines and includes a tool holder and a dismountable holder blade having replaceable cutting inserts, the tool holder including a basic body (10) as well as a support body (11) for the holder blade (7). According to the invention, between the basic body (10) and the support body (11), there is arranged a set-up body (12), by means of which the support body - and thereby the holder blade - can be set and fixed in the exact, desired spatial positions in the machine without time-consuming measuring and fine adjustment operations. In addition, the holder blade is fixed in the support body by means of a single simple screw, which allows a flexible mounting and dismounting of the same.

The invention relates to a method for producing for example a cylindrical surface (Fig. 10) which has a suitable surface structure of a predetermined geometry for applying material by thermal spraying. According to said method, a geometrically defined groove structure (Fig. 10) of minor depth and width is introduced into the surface, for example cylindrical surface, of a substrate to be coated, which surface is premachined to size using a tool which is preferably a follow-on tool (12; Fig. 1), by gradually bringing a groove cross-section to a desired measure. In order for the surface to be producible in series with a constant quality, the groove structure is introduced by first machining a basic groove (52B; Fig. 10) having a groove root width which is smaller than the groove root width of the finished groove (52). The groove, for example at least one flank (52-1 & 52-2) of the basic groove, is then machined in a non-cutting or cutting manner to produce an undercut groove profile, the groove structure produced by introduction being deformed in such a manner that the groove openings are made narrower by upsetting deformation.
