Cutting tool with cooling mechanism and a cutting insert and tool holder therefor
Abstract:
A cutting element includes a cutting portion and a cooling portion. The cutting portion has a rake surface, a relief surface and a cutting edge defined at the intersection between the rake surface and the relief surface. The cooling portion has an operative surface and a cooling nozzle integrally formed therewith. The nozzle is spaced from the cutting edge and having a cooling aperture directed at the cutting edge at an acute angle with respect to the rake surface. The operative surface is one of the rake surface and a surface of the cutting element other than the rake surface, disposed at a location more remote from the cutting edge than the rake surface, so that the rake surface is disposed between the cutting edge and the cooling aperture.
