Hot melt drilling technology
When the tool and workpiece are in contact, high speed (1000~3500) and proper axial thrust (feed force) cause awesome friction between the drill and metal, reaching 650 centigrade instantly. °～ seven hundred and fifty ° The temperature of the temperature. The metal near the bit softens rapidly, and then axial pressure is applied to extrude the boss and bushing about three times the thickness of the initial plate on the upper and lower surfaces of the workpiece.
The whole process only takes 2-6 seconds. For the machining of smooth connecting surface or chamfering hole, plane drill can be used to cut the boss formed on the surface of the workpiece. The bushing can be used as bearing support, branch throat welding joint, etc., and can also be tapped for threaded connection. The thread is formed by rolling, and the processed thread can bear higher tension and torsion.
The chip-free drilling technology is suitable for processing ordinary steel, stainless steel, aluminum, copper, and other workpieces with ductility, as well as electroplated workpieces. It can be used for manual bench drill or CNC machine tools, the required power is 1.5 ~ 3.5kw, and the spindle speed is 1000 ~ 3500r / min. According to the different hole diameter, workpiece material and thickness, the selected cutting parameters are also different. Advantages: high efficiency, economy, saving materials, and the processed workpiece is more beautiful.
