Abstract
A tool for chip removing machining, including a basic body, and a cutting insert fixed in an insert seat in the basic body by a tightening element, and which, via at least one shoulder surface, is held pressed against a stop surface in the insert seat. An elastically deformable spring is arranged in the insert seat, which provides, by elastic deformation as a result of tightening of the tightening element, the pressing of the shoulder surface against the stop surface.
Claims12
A tool for chip removing machining, comprising:
- a basic body;
- a cutting insert fixed in an insert seat in the basic body by a tightening element, and which, via at least one shoulder surface, is held pressed against a stop surface in the insert seat;
- and
- an elastically deformable spring arranged in the insert seat, which provides, by elastic deformation as a result of tightening of the tightening element, the pressing of the shoulder surface against the stop surface,
- wherein the shoulder surface is a flank surface included in a connecting surface of the cutting insert, and the stop surface is a flank surface included in a co-operating, second connecting surface, which forms the insert seat in the basic body, and
- wherein the tightening element is located between the spring and the two co-operating flank surfaces.
A tool for chip removing machining, comprising:
- a basic body;
- a cutting insert fixed in an insert seat in the basic body by a tightening element, and which, via at least one shoulder surface, is held pressed against a stop surface in the insert seat;
- and
- an elastically deformable spring arranged in the insert seat, which provides, by elastic deformation as a result of tightening of the tightening element, the pressing of the shoulder surface against the stop surface,
- wherein the spring is arranged between the cutting insert and the tightening element.
A basic body for cutting tools, comprising:
- an insert seat arranged for the receipt of a replaceable cutting insert, the insert seat including a stop surface against which a shoulder surface included in the cutting insert is pressed;
- and
- an elastically deformable spring included in the insert seat, which provides, by elastic deformation as a result of tightening of a tightening element, the pressing of the shoulder surface of the cutting insert against the stop surface,
- wherein the tightening element is located between the spring and the cooperating shoulder surface and stop surface.
