Abstract
A pipe and tube end preparation apparatus for simultaneously cutting an inside and an outside chamfer on a tube end is herein disclosed. The apparatus generally includes a tube holder and a housing connected to the tube holder. A head carriage mechanism is connected to the housing. The head carriage mechanism is progressively axially movable with respect to the tube holder and the housing. A drive train is rotatably supported by the head carriage mechanism. A cutter head assembly is fixed to the drive train. The cutter head assembly includes an inside chamfer cutter and an opposed outside chamfer cutter, which acts as a cutting guide for the inside chamfer cutter. A tube end, which is to be prepared, is secured by the tube holder. The drive train rotates the cutter head assembly with respect to the tube end. The head carriage mechanism advances the rotating cutter head assembly into cutting engagement with the tube end, thus simultaneously forming an inside chamfer and an outside chamfer on the tube end.
