CL132-5000: Complex machining of tubes SUMMARY: The demand for the use of bars and tubes in various business industries has increased, with regards to high volume applications or for quality niche market products. Thèse two quite varied business fields require différent types of products and spécifie production and working processes. The quality niche market, a more sophisticated demand, has a need for spécial machining processes requiring customized studies and related technological and multidisciplinary know-how and the realization of the proiect to combine creativity and a capacity of innovation. End-machining: the heart of the machining Cell. The model CL132-5000, produced by CAORLE, is an end-working machine which has been specifïcally designed in order to respond to the machining needs of an important French manufacturer of hydraulic cylinders, a product used in a variety of différent fields, i.e.: the displacement of lifts, earth moving machines, elevators and so on. The end-machining is for a variety of différent types of hydraulic cylinders, which is principally chamfering on both ends, the required installation of the machine is in a machining cell, where at the beginning of the line is located a saw to eut the cylinder bodies and at the end of it there is a lapping machine for the internai finishing of the cylinders. Afler thèse opérations the cylinders are moved to the welding phases, one side is closed by welding the bottom part and on the other end is welded the closing-flange, which drives the cylinder-rod in its movement. « Conceived and designed to reply to a spécifie need - says Mr. Alberto Caorle, Managing Director of the Company - the CL132-5000 is structured with four NC axis and two machining units, but it was customized with regards to the main structure (it has a diameter range from 40 mm to 200 mm maximum and a minimum machining length of 300 mm and a maximum of 5.000 mm), with regards to the tooling and also of the automation, in order to respond to the needs of executing the end-machining with référence to the internai diameters, on différent dimensions of hydraulic cylinder of their production, by means of a flexible solution, with high productivity level and a reliable one ». The steel bed of CL132-5000 is an electro-welded and normalized structure made of a thick section heavy-duty steel plate, strategically reinforced for obtaining a maximum stiffness and rigidity. The considérable length (approx. 8.000 mm) required a spécifie designing aimed to achieve the maximum rigidity for the whole length. On the steel bed are positioned the two longitudinal "T" shaped guideways made of hardened and ground steel (the "T" is 100 mm wide) and above them slide the cast iron longitudinal !
