BLM GROUP’s new Lasertube system, the result of years of investment in technological research and the development of innovative software and hardware solutions. It is unquestionably the new benchmark for tube laser systems.
The newest member of the Lasertube family processes tubes from 12 to 152 mm diameter and up to 23 kg/m bar weight. From the smallest to the largest tube, all adjustments are automatic. Sections with open profiles, L and U, and flat bars are considered part of standard machining and are processed in a fully automatic mode.
The 3kW fiber laser source allows great flexibility of thicknesses and materials, from 12 mm of mild steel to 4 mm of brass.
3D machining completes the framework of this extremely flexible system able to tackle the most challenging cutting patterns.
Productivity, quality and accuracy, flexibility, and ease of use: the LT7 has advanced characteristics and performance that fear no comparisons.
The incredibly rapid machining speed is only one of the characteristics that make the LT7 system a real champion of productivity. Experience has shown that a Lasertube system should not be measured in meters per second, but instead in parts produced in the span of a single day.
A fast and effective is exactly where the LT7 shows all its potentialities, with innovative solutions, that come from years of experience, like the scimitar bar change system together with the fully automatic section change, also for special sections. The design of the rollers and chuck mechanism ensure parts are not marred during the process cycle.
Extreme speed during both cutting and production change results in excellent productivity. At the end of a working day when finished parts are counted, the LT7 has produced more parts than the other systems.
Quality and accuracy
The LT7 system is a combination of technological solutions that ensures quality throughout the process.
Between the spindle and the steady rest, the supports driven by controlled axes are equipped with rollers and self-adjusting templates for optimum support both for small, light tubes and for large, heavy tubes. Downstream of the cutting area, the tube is supported by the unloading table, which is also equipped with rollers for side containment. The rollers follow the position vertically providing steady and efficient support. Steadiness of tube during machining is a guarantee of quality and accuracy of cut.
LT7 looks after the quality of the surface of cut pieces from loading to unloading, also in the event of delicate surfaces, by protecting the tube in every phase without ever letting it drop or bumping into items that could damage it.
Finally, the combination of Active Tools and the cutting parameters database assure desired cutting quality with extreme simplicity are achieved. These are the elements that characterize quality and precision obtained from all the Lasertube systems and are present in the LT7.
Flexibility and automated functions
Flexibility is to carry out 3D machining on small tubes as well. The TubeCutter head, with autofocus, specifically designed by BLM GROUP for tube processing, is particularly suitable for 3D machining. The application of 3D machining on medium-sized tubes represents one of the most interesting innovations of the LT7
Loading and unloading of the LT7 system are examples of unmatched flexibility for this class of machine. On the rear side, to ensure maximum reliability, the bundle loading system with pushers has been integrated with a chain loading surface that can be easily interfaced with automatic bar handling systems. On the front side, a wide access to the work area facilitates manual loading of a single tube to be eventually machined in semi-automatic cycle. Flexibility deriving from the use of auxiliary chains for loading the double loader is undoubtedly reflected on productivity. Preparing the next processing on the second loader, while the machine is completing the previous tube bundles, means saving valuable time and producing more parts.
Cut parts, always separated from scraps, are loaded indifferently on front or rear side and deposited on accumulation carriages that receive parts carefully without dropping or dragging them.
Ease of use
The graphical user interface, designed according to ergonomic standards, is extremely clear and easy to use and only a few intuitive operations are necessary to start a new production.
Programming is carried out by the powerful CAD/CAM, Artube which simplifies operations that have required years of experience in field to be developed. With Artube, transformation of a complex frame into machine programs for the LT7 systems is carried out in few seconds.
In the end, the Active Tools are the functions that make operations on machine extremely simple. Just think about how much experience would be necessary to properly set drilling parameters that are automatically managed by Active Piercing or to find out cutting parameters in areas where speed slows down as Active Speed performs automatically in during the machining speed. Active Marking laser marks a part in a rapid and effective way according to parameters. While Active Focus automatically and safely adjusts focus point position.
LT7, as with all BLM GROUP Lasertube systems, can be used in connection with the BLM GROUP bending solutions in an All-In-One work cycle. Integration among production systems, with the exchange of technical information to obtain the realization of a cut or bent part from the first time, is a characteristics of BLM GROUP.
ProTube Enterprise is the MES package developed to plan and monitor production of BLM GROUP systems and in general to interconnect these systems with the company ERP.
The LT7 exploits all potentialities of the software suite BLMelements, together with applications that assist the user in the use of the Lasertube systems.
