Abstract
A milling cutter (10), in particular a side milling cutter, is described, having a tool body (12), to which at least one cutting insert (14) is removably secured, said cutting insert being clamped by means of a movable clamping element (16) in the tool body (12) and comprising a cutting edge (18) pointing in the direction of rotation (R). The clamping element (16) clamps the cutting insert (14) from behind and is arranged on the rear side of the cutting insert (14) in the direction of rotation (R) of the milling cutter (10).
Claims21
A milling cutter comprising:
- a tool body having a movable clamping element, the cutting insert comprising a front contact surface and a rear contact surface on a side opposite the front contact surface;
- and
- at least one cutting insert removably secured to the tool body by the movable clamping element, the at least one cutting insert comprising a cutting edge pointing in a direction of rotation,
- wherein the clamping element clamps the cutting insert from behind and is arranged on a rear side of the cutting insert in the direction of rotation of the milling cutter;
- wherein the tool body and the cutting insert abut against each other flatly in the direction of rotation via the front contact surface;
- wherein rear stop surface force is applied on the rear contact surface of the cutting insert by the front clamping surface of the clamping element;
- and
- wherein the rear stop surface is nonplanar.

A milling cutter comprising:
- a tool body having a movable clamping element, the cutting insert comprising a front contact surface and a rear contact surface on a side opposite the front contact surface;
- and
- at least one cutting insert removably secured to the tool body by the movable clamping element, the at least one cutting insert comprising a cutting edge pointing in a direction of rotation,
- wherein the clamping element clamps the cutting insert from behind and is arranged on a rear side of the cutting insert in the direction of rotation of the milling cutter;
- wherein the tool body and the cutting insert abut against each other flatly in the direction of rotation via the front contact surface;
