At Fabtech 2022 in Atlanta BLM GROUP showcased its LS7 sheet laser cutting machine, a brand-new addition to its line-up resulting from the company’s most current technological research.
The LS7 was designed as an entry-level product in the high-end system segment, i.e. a product with all the features and functionality of a high-end system, but at an attractive price.
The LS7 has a conventional aluminium mobile gantry structure actuated by a rack and pinion system, which slides on a steel base filled with a special polymer to ensure high rigidity even with high accelerations up to 2g. And, the pallet change can be accomplished in only nine second, taking place on the long side of the machine. This speed is attainable thanks to a smart mechanical solution that anticipates the simultaneous exchange of the two tables. Handling is fully electric, without pneumatic or hydraulic actuators, for improved maintenance and energy usage. These features, in combination with the ability to use laser power up to 12kW, makes the LS7 a highly productive machine.
The LS7 can cut steel, stainless steel, iron, copper, brass, and aluminum in thicknesses from 0.20” to 1.57”, or even double sheets, depending upon the material and selected laser power. It is available in two versions – the 3015 with a maximum sheet size of 121.5” x 62.2” and the 4020, capable of handling sheet sizes up to 162.5″ x 79.5″.
Users can add automatic sheet loading and unloading with one or two storage towers for automated material type and thickness changeovers, which is especially well-suited for unmanned operations.
Other features of the LS7 include Plug & Play operations that leads to fast and easy equipment setup, ability to integrate with ERP systems, as well as material handling and storage systems, leading to better interconnectivity. The cutting process can be monitored by the windows near the operator console or by the optional cameras located inside the cabin, the image of which is visible on the operator console, on an additional external monitor and also remotely.
The system comes equipped with the company’s patented Active Tools, which automatically adapt process parameters for optimal results independent of operator experience, ensuring the highest cutting precision and speed. Additionally, an Active Nozzle Changing feature automatically monitors the wear of the cutting nozzle and exchanges it based upon the condition set within the controller.
The system is designed for easy transport with installation completion in just one week.
