The problems of tip burning, can be related to the following situations:<\/span> <\/span><\/p>\n

    \n
  1. a) High rotation (tip firing): The high rotation of the equipment can cause high wear on the screw tip, due to the high friction index, thus generating the breakage of the cutting rod of the screw tip.<\/span><\/li>\n
  2. b) Screw performs two operations at the same time (tip breaking): If the screw is generating two operations at the same time (e.g.: drilling and fastening), the process may slow down the rotation of the screw at the moment of drilling, generating tip burn.<\/span><\/li>\n
  3. c) Extension too long: if the extension is too long, it may decrease the voltage of the screwdriver, generating a decrease in rotation, making the drilling process more difficult, and causing the tip to burn.<\/span><\/li>\n
  4. d) Boring holes outside the specification (tip flaring): The screw must pierce the specified range of each tip, according to the Hard Technical Bulletin. Drilling above this range causes the tip to burn out.<\/span><\/li>\n<\/ol>\n

     <\/span><\/p>\n

    SOLUTION<\/span><\/b> <\/span><\/p>\n

    The possible solutions for tip burning are listed in the following alternatives:<\/span> <\/span><\/p>\n

      \n
    1. a) Use the appropriate equipment, according to Hard specification, of maximum rotation of 2500 RPM and 15Nm of wrench.<\/span><\/li>\n
    2. b) During the installation process, the screw should perform one operation at a time, such as:<\/span><\/li>\n<\/ol>\n

      1\u00ba) Drilling;<\/span> <\/span><\/p>\n

      2\u00ba) Laminate;<\/span> <\/span><\/p>\n

      3\u00ba) Screw;<\/span> <\/span><\/p>\n

      This prevents loss of speed during the process and, consequently, burning of the tip.<\/span> <\/span><\/p>\n

        \n
      1. c) Work with extensions of a maximum of 2 meters, preventing loss of tension.<\/span><\/li>\n
      2. d) Work according to the drilling range specified in the Hard’s Technical Report, checking the comparative between: TIP TYPE X PURLIN THICKNESS.<\/span><\/li>\n<\/ol>\n","protected":false},"featured_media":0,"template":"","categoria_de_perguntas":[234,358],"class_list":["post-21986","faq","type-faq","status-publish","hentry","categoria_de_perguntas-parafusos","categoria_de_perguntas-screws"],"acf":[],"yoast_head":"\nThe screw is burning the tip.
