Abstract
A machining tool, in the area of a tool tip, includes an integrated cooling structure for transporting a coolant. The cooling structure is optionally or in combination designed as a porous structure or at least one cooling channel having a bent reversing segment, so that two channel segments are oriented in opposite directions. The cooling structure is integrated into a base body of a carrier tool. According to a method of the invention, the cooling structure is manufactured by means of a 3D printing method.
Claims7
A machining tool that extends in an axial direction along a rotational axis and comprising:
- a tool tip;
- a base body, the base body forming retaining webs between which a tool tip can be inserted and having an integrated cooling structure for conducting a coolant or lubricant, the cooling structure being integrated at least partly in the retaining webs;
- and
- a chip flute formed in the base body, the chip flute having a chip flute wall,
- wherein the cooling structure, at least in sections, is designed as a porous structure having a plurality of pores;
- wherein at least a portion of the porous structure is located in the retaining webs of the base body and the porous structure exits at an outlet point provided on the chip flute wall;
- and
- wherein the porous structure has a porosity ranging between 5% and 90%.
