Abstract: An automated tube trimming system accurately trims tubes to the correct height and angle. The tube trimming system is a combination of an automated trimming saw and a unique spherical tube clamping system. A spherical clamp having a fixed clamp section and an internal swivel portion is used to clamp a tube at an appropriate angle for cutting in an automated tube trimming saw. The spherical clamp may be tightened onto the tube at an angle appropriate to provide the correct mating cut to easily weld to a second mating tube section or fitting. Conventional methods cut perpendicular to the direction of the tube, thereby requiring time consuming and labor intensive grinding and deburring. The ability to provide accurate and simple formation of trimmed tubes may be useful in a wide variety of industries where the movement of air and fluid through tubes is performed.
