Hot melt drill is manufactured through special craft processing of cemented carbide and high speed rotary drill when in contact with the metal material friction moment of the machining of high temperature over 600 degrees, make the hot melt drill area metal softening quickly, with the rotation of the drill bit and press, squeezed Kong Chao stretch up and down along the circle part of the metal, forming three times thicker than the original metal metal convex sets, the convex platform can be tapping, screw tooth extrusion molding, strengthening the coupling effect. Hot melt drill of the whole process does not destroy the structure and properties of metal materials, also for the whole process is a chipless machining, the machining of screw hole high tensile resistance and high torque performance.
Hot melt drill processing advantages and scope of application:
1, advantages: improve product quality, improve production efficiency, reduce production cost, clean environmental protection.
2, scope of application: metal furniture, metal doors and Windows, metal shelves, auto parts and so on
