Profile: Alpha Metall GmbH & Co. KG specializes in offering machinery for welded tube manufacturers. Our product line consists of tungsten carbide cutting rings, oscillating outside diameter scarfer, external tube scarfing, 3-stations-strip shaving unit and bead chopper. Our 3-stations-strip shaving unit scarfs the edge and wants to shave the aluminum coating from top and bottom of the strip. The unit is provided with a sequence for opening and closing the side guide rollers. Our product has strip size changeover. The cutters are provided with chip breakers as to direct the chips down into a container. Our oscillating outside diameter scarf is designed for tube outer diameter of 1/2" to 4" or 2" to 6.3". The round cutting head has 3 cassettes holding 3 tungsten carbide blades. The scarfer constantly oscillates over the length of one cutting blade, obtaining a perfect surface finish and dividing the wear over the length of the cutting edge, resulting in an edge life. The cutter swings by a push button to the new selected blade within 1.5 seconds and will start oscillating again. Three blades will give an one-shift-outside-scarfing without manual tool change.
