Kennametal Extrude Hone is a thermal energy machining technology for complex finishing challenges. A pressurised mixture of a combustible gas and oxygen is injected at 5 to 10 atmospheres of pressure into a containment chamber sized both by the amount of material to be removed and the volume of parts in the chamber. An ignition system ignites the gas mixture, releasing heat energy from the oxidation of fuel in a 20-millisecond, high-speed energy wave.
The company claims that internal burrs and flashings burn away instantly. Because the gas mixture engulfs the entire workpiece, all internal and external surfaces are exposed to the rapid oxidation. Internal cross-drilled holes and intersecting edges that are difficult or impossible to reach are instantly processed.
