MÉTODO DE FABRICAÇÃO DE UMA FERRAMENTA ROTATIVA PARA A MAQUINAÇÃO DE REMOÇÃO DE CAVACO

摘要

A method for manufacturing a rotary tool for chip removing machining with a least one chip flute that extends in the longitudinal direction of the tool. The method involves preparing a mixture of a cemented carbide, cermet or ceramics powder and a carrier, such as a polymer, and placing the mixture in an extruding machine. The mixture is extruded in a feed direction by means of a die to form the diameter of the mixture body. The mixture body passes against a chisel which forms a chip flute in the outer periphery of the
