Friction drilling

Friction drilling is a method of making holes in metal in which the material is pushed out of the way with the aid of heat from friction. The process is also called thermal drilling, flow drilling, form drilling, or friction stir drilling. Friction drilling is commonly used on bicycle frames, heat exchangers, and to create … See more In 1923, the Frenchman Jean Claude de Valière tried making a tool that could make holes in metal by friction heat, instead of by machining. It was only a moderate success, because at that time the right materials were not … See more Friction drilling uses a conical bit made of very heat-resistant material such as cemented carbide. This device is pressed against a target … See more • Friction drilling is not possible in massive material since displaced metal must be able to flow somewhere.

A novel method of friction drilling technique review - AIP Publishing

WebFriction drilling is a non-traditional hole-making method that utilizes the heat generated from friction between a rotating conical tool and the work-piece to soften and penetrate the work-material and generate a hole in a thin-walled work-piece. It forms a bushing in-situ from the thin-walled work-piece and is a clean, chip-less process. WebFeb 1, 2016 · A friction-drilling, or flow-drilling, screw is a self-piercing and extruding fastener for joining layers of sheet metal. Combining the properties of friction drilling and thread forming, the screw acts as both a fastener and a drilling-and-tapping tool. It penetrates the layers, extrudes a short boss, forms its own threads, and applies ...
