摘要:
The present invention relates to a thread-milling cutter (13), which includes a cutting head (14) with a number of cutting insert pockets (18), a number of thread-milling inserts (1), which are received in said cutting insert pockets (18) and an attachment (16) integral with the cutting head (14), which is intended to be received in a tool coupling. The present invention also relates to a thread-milling insert (1), which is mounted in the thread-milling cutter (13). The thread-milling cutter according to the present invention is characterized in that at least one threaded hole (19) is provided in connection with each cutting insert pocket (18) which communicates with the associated cutting insert pocket (18), that a screw (17) is received in each of the threaded holes (19), that said screw (17) is in direct contact with a surface (10) of a securing portion (5) of the thread-milling insert (1) to secure the same in its cutting insert pocket (18), and that said surface (10) forms an acute angle (β) with a main plane (L) of the thread-milling insert (1).

The present invention relates to a method of making cutting tool inserts with high demands on dimensional accuracy by - mixing by milling of powders forming hard constituents and binder phase, - forming the powder mixture to bodies of desired shape, - sintering the formed bodies, - grinding with high accuracy the sintered bodies to inserts with desired shape and dimension, - possibly edge rounding of cutting edges and - providing the ground inserts with a wear resistant non-diamond or non-diamond-like coating. According to the method the ground inserts are heat treated prior to the coating operation in an inert atmosphere or vacuum or other protective atmosphere below the solidus of the binder phase for such a time that the micro structure of the surface region is restructured without causing significant dimensional changes. In this way inserts with unexpected improvement of tool life and dimensional accuracy have been achieved.

Die Erfindung betrifft Gewindewerkzeug umfassend einen Schaft (1) und einen Profilkörper (3), wobei der Profilkörper (3) zum Scheiden oder Formen eines Gewindes ausgelegt ist, wobei der Schaft (1) aus einem ersten Material in einem Volumenformverfahren und der Profilkörper (3) aus einem zweiten Material mit einem additiven Verfahren hergestellt ist.
摘要:
A cutting tool body is disclosed, comprising a first member and a second member, both having a substantially cylindrical shape, and arranged such that a tool body central axis coincides with a central axis of each of the first and the second members. The first member has a tool characteristic of a first magnitude, and the second member has the tool characteristic of a second magnitude, different from the first magnitude. The cutting tool body comprises a transition member arranged between the first and second members and connected at a first end to the first member and at a second end to the second member. The tool characteristic in the transition member is of the first magnitude at the first end, and of the second magnitude at the second end. The transition member comprises a transition region between the first and the second ends in which the tool characteristic transforms from the first magnitude to the second magnitude.
