Abstract
The invention relates to a milling tool (1) having a length ltotal and diameter dtotal and having blades (2) for the milling of mostly metal workpieces. In order to prevent an uncontrolled failure of the milling tool, it is proposed that the blades (2) are partially or entirely made of polycrystalline cubic boron nitride (PcBN) or polycrystalline diamond (PCD) and the diameter dtotal of the milling tool lies between 7 mm and 40 mm.
Claims14
A milling tool comprising blades for the milling of workpieces, wherein the milling tool has a length ltotal and diameter dtotal, wherein said blades are partially or entirely made of polycrystalline cubic boron nitride or polycrystalline diamond and the diameter dtotal of the milling tool is between 7 mm and 40 mm, wherein the cutting part is joined to the base body by positive interlocking, wherein a recess is arranged on the bottom of the cutting part which faces the base body and on the top of the base body which faces the cutting part, wherein said recesses are arranged in line with one another with respect to the longitudinal axis and, in the assembled state of the cutting part on the base body, form a mounting space in which a driving dog is brazed, and wherein at least one raised driving dog is arranged on the bottom of the cutting part which faces the base body and at least one driving dog depression matched to the driving dog arranged on the top of the base body which faces the cutting part and, in the assembled state of the cutting part on the base body, and
- wherein the driving dog engages in the driving dog depression and is brazed therein.
