Скачать или смотреть Stainless steel square tubewith hot-melt friction drilling and tapping.

Hot fusion friction drilling is a thin-walled metal products stretching technology, it changed the traditional drilling fastening process, making the previous processing of thin-walled metal can not be tapping the problem of thin plates and tubes tapping fastening can be easily solved in a few seconds. This process is used to replace the drilling, instead of welding nuts, instead of riveting nuts. The drill bit of the hot melt drill is made of tungsten carbide material, which produces 600 degrees high temperature at the moment of high-speed rotation contacting the surface of the metal material to be processed, and the high temperature softens the metal and enhances the ductility of the metal. Through the rotation and downward pressure of the drill bit, the extruded part of the metal extends along the round hole toward the top and bottom, forming a thick wall layer three times thicker than the original metal. The entire process of hot drilling does not destroy the structure and properties of the metal material. At the same time, the thick wall layer formed has high resistance to force and torsion, and can be used directly for high-quality tapping.
