Abstract
A machining tool, in particular a drill carrier tool, includes a monolithic base body extending in the axial direction which, at least in one section, has a porous or grid-like core structure that is encased in a solid outer jacket. These measures allow less material to be used, while maintaining good mechanical properties. The porous or grid-like core structure is simultaneously used for transporting coolant. The base body is manufactured in particular by means of a 3D printing method.
Claims11
A rotary machining tool comprising a monolithic base body extending in an axial direction and comprising a rear shaft part and a fluted cutting part, wherein the base body has a non-solid core structure extending between flutes of the cutting part, the non-solid core structure being encased in a solid outer jacket, the solid outer jacket forming a single body with the non-solid core structure and wherein the non-solid core structure spans uninterrupted from the rear shaft part to the cutting part and without partition.
