Abstract

"FERRAMENTA DE PERFURAçãO PARA PRODUçãO DE FUROS EM PEçAS DE TRABALHO METáLICAS". A presente invenção se refere a uma broca com sulcos de carregamento de cavacos e um cabeçote de broca em sua extremidade dianteira, com pelo menos duas inserções de corte. Cada inserção de corte é dotada de pelo menos uma borda de corte que é delimitada entre uma superfície de frenagem de cavacos e uma primeira superfície de alívio e que inclui uma borda reta externa. Na proximidade do eixo central do fuso, é proporcionada uma seção de borda de corte curva, à qual é conectado um chanfro de reforço adjacente. A borda de corte se encontra em direta proximidade a um eixo central, sendo terminada por um gume entre as inserções de corte, que serve como uma porção de núcleo de centralização. A seção de borda de corte curva quando dirigida internamente é acompanhada por uma porção reta principal, sem um chanfro de reforço de ajuste, numa direção que é orientada em um ângulo que se situa entre aproximadamente 40-50<198>, em relação a uma linha horizontal que se estende através do eixo central da broca.
