Abstract
The chip removing machining of a workpiece is performed by a cutting tool which includes a cutting insert. In order to cool the cutting insert, one or more over-cooling nozzles is arranged for directing a jet of cooling liquid downwardly toward a contact area between the workpiece and a chip surface of the cutting insert. A sub-cooling nozzle is arranged for directing a jet of cooling liquid upwardly toward a contact area between the workpiece and a flank surface of the cutting insert. A jet of cooling liquid can be emitted from only the over-cooling nozzle, or from only the sub-cooling nozzle, or from both of those nozzles simultaneously.
