Abstract: A method and apparatus for producing a finned tube comprises the step of securing a tube to a tube clamping device. The method also comprises the step of arranging a plurality of cutters within the cutter head, wherein the cutters rotate with the cutter head. The method also comprises a step of moving the cutter heads into position around the tube and rotating the cutters around an outside surface of the tube in order to cut fins, via the removal of material, into the outside surface of the tube. The removal of the material also will allow for a very thin inner wall to be arranged underneath the fins being cut therein. This methodology will allow for a very light weight, thermally efficient finned tube to be used to produce a heat exchanger for use in turbine engines or the like.
