摘要： A tool intended for chip removing machining is disclosed. The tool is of the type that has a basic body and an indexable cutting insert that can be connected to the basic body via an interface including a primary connecting surface in the basic body and a secondary connecting surface in the cutting insert. Among two cooperating support flanks included in the connecting surface of the basic body, one is situated on a level above the other in order to form a lateral support for the cutting insert. In the connecting surface of the cutting insert, contact flanks are included that, together with the clearance surface of the cutting insert, form a V-shapedly converging wedge part that can be applied in a seat delimited by the support flanks, the contact flank being urged against the low-positioned support flank of the basic body, while an upper part of the clearance surface of the cutting insert is urged against the high-positioned support flank. By means of the high-positioned support flank, large cutting forces can be carried in a dominant line of action, the interface in other respects efficiently counteracting such tendencies to dislodging/turning of the cutting insert that are caused by more moderate forces in other lines of action. In addition to the proper tool, a cutting insert and a basic body for the tool, per se, are also disclosed.

摘要： A tool for the fine-turning of grooves in workpieces including a basic body having a rearwardly extending mounting part, and a forwardly projecting bracket. The bracket includes a narrow neck part and an enlarged support part disposed at an end of the neck part. The support part, which forms an insert seat, extends laterally from the neck part wherein the seat is arranged asymmetrically with respect to an imaginary center line of the basic body. A cutting insert includes a bottom side supported on the insert seat. The insert includes two spaced apart convexly arched side cutting edges arranged so that the imaginary center line passes therebetween. A hole is provided through the insert for receiving a fastening screw. The bottom side and the insert seat include mutually engaging stabilizing structures preventing angular displacement of the insert about an axis of the hole.
