Abstract
Tube ends such as those of boiler tube banks, are prepared utilizing any of various combinations of processes which include a step of micro-diameter tube film removal from a portion of a tube end, including an area below a beveled segment, or segment to be beveled. The micro-diameter film removal step provides the tube with an exposed, clean metal surface which is conducive to a subsequent welding or bonding operation performed on the tube. In yet a further embodiment, tube film removal blades are provided having a curved or rounded edge which can be utilized in milling operations having close quarters. In a further embodiment, milling head cutting blades are provided which are adjustable. In a preferred embodiment, the milling head cutting blades and/or bevel blades are provided with elongated, slotted bores.
