Vamos entender tr\u00eas tipos diferentes de brocas<\/p>\n

Brocas de centro<\/em><\/strong><\/h4>\n

Consiste em ponta de broca, aresta de corte e canal de cavacos<\/p>\n

\u00c9 usado principalmente para ampliar o furo com um furo pr\u00e9-moldado ou furo inferior e melhorar a cilindrica e o volume, mas o furo ainda n\u00e3o est\u00e1 neste momento<\/p>\n

Usar<\/em><\/strong><\/p>\n

    \n
  1. Geralmente \u00e9 usado para semi-acabamento ou usinagem final de furos<\/li>\n
  2. Para pr\u00e9-processamento de dobradi\u00e7as ou retifica\u00e7\u00e3o<\/li>\n
  3. Para expans\u00e3o de furos \u00e1speros<\/li>\n
  4. Pode ser usado como pinhole<\/li>\n<\/ol>\n

    Brocas centrais t\u00eam 3 a 4 bandas de borda, sem bordas de corte e corte de canto frontal e traseiro<\/p>\n

    Vantagem<\/em><\/strong><\/p>\n

      \n
    1. A mudan\u00e7a da l\u00e2mina \u00e9 pequena<\/li>\n
    2. O efeito de guiamento \u00e9 bom durante a usinagem<\/li>\n
    3. A resist\u00eancia \u00e9 pequena<\/li>\n
    4. As condi\u00e7\u00f5es de perfura\u00e7\u00e3o s\u00e3o subdivididas em furos de perfura\u00e7\u00e3o<\/li>\n<\/ol>\n

      \"Broca<\/p>\n

      Mais sobre a broca central<\/p>\n

      A broca<\/em><\/strong><\/h4>\n
        \n
      1. Composto por ponta de broca, aresta de corte e canal de cavacos<\/li>\n
      2. Processa principalmente furos de pe\u00e7as sem furos pr\u00e9-fabricados<\/li>\n
      3. Os furos processados s\u00e3o geralmente de baixa cilindrada e volume<\/li>\n
      4. \u00c9 amplamente utilizado na perfura\u00e7\u00e3o de metal ou outros materiais<\/li>\n<\/ol>\n

        Mais sobre as brocas helicoidais<\/p>\n

        A broca e a broca central s\u00e3o as mesmas coisas, mas t\u00eam fun\u00e7\u00f5es diferentes<\/em><\/strong><\/p>\n

        Ambos usam a aresta de corte para perfurar<\/em><\/p>\n

        A broca de perfura\u00e7\u00e3o no orif\u00edcio inferior e a broca central ampliam o orif\u00edcio inferior da broca<\/em><\/p>\n

        \"Broca<\/p>\n

        Alargador<\/em><\/strong><\/h4>\n

        Usar<\/em><\/strong><\/p>\n

          \n
        1. O alargador usa l\u00e2minas laterais para cortar<\/li>\n
        2. O alargador \u00e9 usado para escarear para obter a precis\u00e3o e o acabamento do furo<\/li>\n
        3. Um alargador \u00e9 um tipo de ferramenta de corte rotativa usada em metalurgia<\/li>\n<\/ol>\n

          Composi\u00e7\u00e3o<\/em><\/strong><\/p>\n

            \n
          1. Consiste em aresta de corte e canal de cavacos<\/li>\n
          2. \u00c9 usado principalmente para melhorar a circularidade e o deslocamento do furo inferior<\/li>\n<\/ol>\n

            \"Alargador\"<\/p>\n
