The L1.it laser machine with integrated MCL Cartesian manipulator for laser systems and the new ADL loader/unloader for a high degree of automation was launched at EuroBLECH in October..
One of the most important new features of the L1.it is the new focusing head, which has been totally redesigned and will now accept both 5” and 7.5” lenses. Another important innovation is the motorised balanced lens axis, which has reduced cycle times while increasing cutting quality. In fact, the cutting pressure now required has been shown to be 1-1.5 bars lower than usual, allowing a 10-15 per cent reduction in cutting gas consumption and a significant decrease in annual running costs.
The L1.it also features an improved fume extractor and a new chiller that is smaller and consumes less power than the previous version; the independent external air dryer has been made more powerful, improving the quality of the air in the optical path and blower devices, and the lens cooling system has been modified.
Improvements have been made to the nesting software, almost guaranteeing perfect blank use and common cut optimisation to minimise scrap percentages.
The new, fully centralized Salvagnini SiX controller features digital drives that are the result of important technical cooperation between Moog, Comau and Salvagnini and represent the state-of-the-art in terms of performance and economy.
The MCL connection is the new Salvagnini solution for picking up and stacking the parts processed on laser systems. Cut parts of many different sizes can be picked up from the processed sheet: the suction cups move independently to take the smallest ones (down to 100 mm long), whereas the two gripping devices move together synergistically in order to lift the largest ones (over 2,000 mm long).
With the integration of the brand new ADL component, Salvagnini has completed the automation of its laser systems. The ADL loads the starting sheets and unloads both the scrap and the parts that remain on the worktable, eliminating the intermediate processing phases (pick-up/ stacking) and leaving the operator free to perform other tasks.
