Abstract
An integral cutting tool configured for revolving about a central axis is provided. The cutting tool is formed with at least one cutting portion having a rake surface, a relief surface, and a cutting edge formed at the intersection between the rake surface and the relief surface. The cutting tool is further provided with a cooling fluid provision arrangement having at least one passage, and a cooling aperture formed at the relief surface. The cooling aperture is directed towards the cutting edge at an acute angle.

An integral cutting tool configured for revolving about a central axis thereof, said cutting tool being formed with at least one cutting portion having a rake surface, a relief surface and a cutting edge formed at the intersection between said rake surface and said relief surface, said cutting tool being further provided with a cooling fluid provision arrangement having at least one passage and a cooling aperture formed at the relief surface, said cooling aperture defining an aperture plane thereacross, the cooling provision arrangement being configured to emit a cooling fluid along a cooling axis perpendicular to the aperture plane, said cooling axis being directed towards the cutting edge and intersecting the cutting edge at an acute angle.
A cutting tool comprising a cutting element and a cutting tool holder, the cutting element comprising top and bottom faces and at least one side face extending therebetween, a cutting portion and a cooling portion, said cutting portion having a rake surface on at least one of said top and bottom faces, a relief surface on said side face, and a cutting edge defined at the intersection between the rake surface and the relief surface, said cooling portion comprising:
- a portion of at least one of the top and bottom faces other than the rake surface, disposed at a location more remote from the cutting edge than the rake surface and constituting an operative surface;
- and
- a cooling nozzle integrally formed therewith and having a cooling aperture directed at the cutting edge at an acute angle with respect to the rake surface, said rake surface being disposed between the cutting edge and the cooling aperture;
- wherein said cooling nozzle is constituted by at least one side wall extending transverse to said operative surface and upper face extending transverse to said side wall so that said cooling aperture is delimited by said operative surface, said side wall and said upper face, and wherein said cutting element is further formed with a cooling passage extending between said bottom face and said top face and being in fluid communication with said nozzle for provision of a cooling fluid thereto;
- said cutting tool holder being configured for mounting thereon said cutting element and being formed with an insert seat for receiving the cutting element therewithin and a cooling fluid provision arrangement having at least one cooling channel in fluid communication with said insert seat.
