Abstract

1 / 1 resumo “sistema de perfuraã‡ãƒo, e, processo para montagem de um sistema de perfuraã‡ãƒo” sistema de perfuraã§ã£o (10) que melhor utiliza a curva de forã§a das mã¡quina-ferramenta moderna. o sistema de perfuraã§ã£o (10) usa uma perfuraã§ã£o de duas etapas, utilizando inserã§ãµes ic (50) para realizar o corte de diã¢metro de furo principal, e um sistema de perfuraã§ã£o central (70). nos exemplos, as inserã§ãµes ic (50) podem ser estabelecidas em um cabeã§ote de perfuraã§ã£o (30) em uma configuraã§ã£o eficaz ãºnica ou dupla. um sistema de perfuraã§ã£o central (70) corta a parte de diã¢metro menor remanescente do furo, e ã© configurada para ver menos comprimento total da superfã­cie de corte, devido a sua posiã§ã£o a partir do centro rotativo da ferramenta. o sistema de perfuraã§ã£o central (70) pode incluir uma geometria de “autocentralizaã§ã£o”, de modo que o cabeã§ote de perfuraã§ã£o (30) da ferramenta seja guiado por toda a profundidade do furo. o sistema de perfuraã§ã£o (10) permite que um furo profundo de grande diã¢metro permaneã§a inteiramente reto para ser perfurado em velocidade mais elevadas e taxas de alimentaã§ã£o mais leves, oferecendo assim uma ferramenta mais produtiva que tem a vantagem das curvas de forã§a e menor capacidade de impulso das mã¡quinas-ferramentas modernas.
