BLM unveils LS7 sheet metal cutting system
BLM GROUP unveiled its new LS7 sheet cutting system at EuroBLECH this year. The system is 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. It has a conventional aluminium mobile gantry structure actuated by a rack and pinion system, which slides on a very strong metal structure, filled with polymer concrete to ensure high rigidity even with high accelerations up to 2G. It can be fitted with 3-12kW laser power.
BLM claims the system can achieve no burrs on metals of a wide range of thicknesses. The laser-cutting head automatically adapts to the thickness and type of material (stainless steel, aluminum, mild steel, copper, and others) to ensure clean, precise and consistent cuts. The cutting area has been designed to protect the bellows from the glowing sparks thrown in all directions, especially during piercing. Access is only from the short side and the entire machine remains completely enclosed for safety reasons related to the fibre laser source. The cutting process can be viewed by means of a camera, the image of which is visible on the operator console, on an additional external monitor and also remotely.
The pallet change takes place on the long side in only nine seconds thanks to a smart mechanical solution anticipating the simultaneous exchange of the two tables. Handling is fully electric, without pneumatic or hydraulic actuators. LS7 is available in both 3 x 1.5m and 4 x 2m versions. Additional options include many loading-unloading automation solutions with one or two towers. The system is designed for easy transportation. Installation takes just one week, including training.
