As brocas centrais s\u00e3o usadas para a usinagem de furos centrais nas faces finais de eixos e outras pe\u00e7as<\/h5>\n
    \n
  1. \u00c9 usado para o posicionamento preciso de furos pr\u00e9-fabricados<\/li>\n
  2. Guia as brocas helicoidais para realizar o processamento de furos para reduzir erros e localizar os furos com precis\u00e3o<\/li>\n
  3. \u00c9 a superf\u00edcie de base de posicionamento para instalar a pe\u00e7a de trabalho do tipo eixo no centro<\/li>\n
  4. O orif\u00edcio c\u00f4nico de 60 \u00b0 no orif\u00edcio central corresponde \u00e0 superf\u00edcie c\u00f4nica de 60 \u00b0 na ponta Ding<\/li>\n<\/ol>\n

    As brocas centrais t\u00eam tr\u00eas tipos<\/h4>\n
      \n
    1. Tipo A: Broca central sem cone de prote\u00e7\u00e3o<\/li>\n
    2. Tipo B: Broca central com cone de prote\u00e7\u00e3o<\/li>\n
    3. Broca de centro composto: use sozinha e tamb\u00e9m pode usar em diferentes equipamentos mec\u00e2nicos<\/li>\n<\/ol>\n

      Ao usinar furos centrais com um di\u00e2metro de d = 2 ~ 10 mm<\/strong><\/p>\n

      Geralmente usa o tipo A<\/p>\n

      Ao usinar furos centrais com di\u00e2metro superior a 10 mm<\/strong><\/p>\n

      Voc\u00ea pode usar o tipo B<\/p>\n

      Geralmente use essas brocas para o processamento do furo central<\/p>\n

      Selecione de acordo com o furo central \u00e9 diferente<\/p>\n

      O uso da broca central \u00e9 o seguinte:<\/h4>\n
        \n
      1. Antes de usar a ferramenta, \u00e9 necess\u00e1rio lavar a graxa antiferrugem para evitar que os cavacos grudem na aresta de corte e afetem o desempenho de corte<\/li>\n
      2. Selecione o tipo de broca de acordo com o tipo de furo e o tamanho do furo reto da pe\u00e7a usinada<\/li>\n
      3. A dureza da pe\u00e7a de trabalho \u00e9 melhor entre 170-200HB<\/li>\n
      4. A superf\u00edcie da pe\u00e7a de trabalho deve ser reta, sem tracoma ou pontos duros, para n\u00e3o danificar a ferramenta<\/li>\n
      5. Antes da perfura\u00e7\u00e3o deve atingir a precis\u00e3o de posi\u00e7\u00e3o necess\u00e1ria<\/li>\n
      6. Quantidade de corte. Fluido de corte: Escolha diferentes fluidos de corte de acordo com o objeto de processamento, e o resfriamento deve ser suficiente<\/li>\n<\/ol>\n
