Rotierendes Schneidwerkzeug.

摘要

A rotary cutting tool is disclosed which has a tool body (1), a cutting insert (4), a clamp member (14) and a clamp screw (19). The tool body has an insert-receiving recess (3) and a clamp member-receiving aperture (15) formed in an outer surface thereof. The insert-receiving recess has a bottom and at least two bearing walls disposed so as to be inclined with respect to each other. The clamp member-receiving aperture (15) is disposed so as to be communicated with the recess. The cutting insert (4) includes a plate having a front face serving as a rake surface and a rear face. The cutting insert (4) is releasably received in the recess with the rear face being mated with the bottom, in such a manner that the front face is partly located in the clamp member-receiving aperture (15). The clamp member has an axis therethrough and an engagement portion. The clamp member (14) is releasably accommodated in the clamp member-receiving aperture so as to be axially slidable, with the engagement portion being held in abutment with the front face of the cutting insert. The clamp screw (19) is threaded into the tool body so as to be held in abutting engagement with the clamp member, to thereby press the clamp member against the insert. The clamp screw is preferably arranged such that an angle defined between the axis of the clamp member and the front face of the insert ranges from 30 degrees to 60 degrees. The clamp member is preferably arranged such that as viewed from the rake surface, the clamp member (14) extends in a direction toward the at least two bearing walls.
