machining even on particularly irregular tubes, preventing dangerous mechanical stress on the mandrels. The plant is governed and automatically controlled by two CNC controls: one for the handling area and the other for the laser working area (Sphera). A third CNC control manages and supervises the laser source. The three computers are set to interact with one another and do not need human operation. Automatic operations are carried out for profile loading, dimensional control, 3D laser machining and discharge of the machined parts. The FL 600 3D has 30 controlled axes and can accommodate a maximum tube length of 24,000mm. It holds a maximum round section size of Ø 610mm, a maximum square section size of 400x400mm, a maximum rectangular/oval size of 500x300mm, and a maximum IPE section size of 550mm. The maximum section size loading from the bundle is Ø 254mm. Other specifications include a laser resonator power of up to 4,000W, a mandrel linear speed of 45m/min, and axis acceleration of 13m/sec 2 .

Tube Tech Machinery is specialised in the design and production of 3D laser cutting machines for tube, pipe and sheet metal. The company will exhibit the FL 600 3D cutting machine that provides precision, quality and productivity tube working for diameters ranging from 80-610mm. The tri-dimensional system allows the user to operate on any point in a sphere space, while the movement along 5 interpolated axis, with precision ball screws and linear motors, ensures high dynamics and excellent performance. FL 600 3D is equipped with a double tube loading system. One system is a bundle loader, which allows the automatic loading of tubes with round, square and rectangular section, with a loading capacity of 10,000kg. The other system operates via a chain, which enables the loading of open section profiles. It is composed of V shaped supports: the chains move at variable speed, according to the tube diameter and weight, and slide on bearings to prevent noise and wear.

The movement of the piece along the working axis is guaranteed by four self-centring mandrels, activated by synchronised hydraulic cylinders. A tempered and rectified precision helical toothed rack activates the advance, operated by brushless motor and precision reducer with slack recovery system. The mandrels are designed to allow the machining of different diameters and sections, with no change of tools. An integrated floating system compensates for uneven piece straightness during machining. This enables precision › The FL 600 3D laser cutting machine from Tube Tech Machinery
