EuroBlech 2024 in Hanover last month saw Italy-headquartered BLM Group present its LS7 sheet metal laser cutting system with a 20 kW power source and automatic warehouse for 24/7 continuous production. The new 20 kW LS7 retains all the features of the company’s lower power versions.

According to BLM, the LS7 is a compact, high-performance laser machine with a fast pallet-change time of just 9 seconds. Laser cutting head sensors and specific active tools serve to optimise the automatic cutting process and maximise energy efficiency. Thanks to its fibre source, the machine can process a wide variety of metals, including aluminium, brass, stainless steel, copper and mild steel.

The LS7’s gantry structure combines aluminium and polymer concrete elements to give strength and lightness to the machine, aiding acceleration beyond 2 g. BLM paid special

attention to ergonomics and ease-of-use, with the HMI and windowed door located next to the operator console, which allows access to the work area (with the machine off) for cleaning or maintenance operations.

At EuroBlech, the machine featured a gas mixer system that blends gases automatically to improve cutting quality and speed further. The system requires no special maintenance procedures or extra space for installation as it is fully integrated into the machine.

BLM’s LS7 not only occupies minimal floor space but can also feature various systems for sheet metal automation, such as loading/unloading or compact tower storage.

Other solutions on display at the show include the Lasertube LT7 for tube cutting and a five-axis 3D laser cutting cell for processing 3D metal profiles.

At EuroBlech 2024 in Hanover last month, Trumpf presented a completely new solution for the automated sorting of 2D laser-cut parts. With the SortMaster Station and SortMaster Vision, customers can sort parts reliably without any programming effort.

The key to this capability is that the SortMaster Station removes parts from the sheet metal in the first step, regardless of their geometry. The machine operator then sorts the separated parts manually or has them removed and palletised fully automatically by the SortMaster Vision. Meanwhile, the laser cutting machine is already processing the next sheet.

“The automated sorting of parts is one of the biggest challenges in the sheet metal world,” states Trumpf’s CTO for machine tools Thomas Schneider. “Conventional methods are suitable for simple components with medium sheet thickness up to 12 mm. For many companies, their common automation solutions are too inflexible and time-consuming to program, so they sort parts by hand. With the SortMaster Station and SortMaster Vision, Trumpf enables automated sorting of any sheet metal components.”

Trumpf offers its customers the new solution in a 3 m format for laser cutting machines within its 3000 and 5000 series.

The solution uses the Trumpf LiftMaster Compact loading and unloading automation system. It removes the cut sheet from the pallet changer of the machine and transfers it to the SortMaster station. This separates the components from the scrap skeleton in just a few seconds. The separated parts are then conveyed to the sorting area.

“With our solution, we have decoupled the cutting, separating and sorting processes from each other for the first time,” concludes Schneider. More information www.trumpf.com

Yamazaki Mazak has introduced its latest innovation in 2D laser cutters: the OptiPlex Ez series. The new range includes two introductory models, the OptiPlex 3015 Ez and 4220 Ez, designed to offer customers a user-friendly experience, affordability and high performance levels.

Mazak says that its OptiPlex Ez series offers high mechanical rigidity for precision cutting and reliability. Intelligent functions empower users with supportive and preventive measures, minimising set-up times for higher productivity. The OptiPlex Ez is for customers seeking a straightforward entry into laser cutting technology, with simplified functions that combine with an integrated cutting database.

Among the stand-out features is the new auto-focus torch and new fibre resonator that enhance adaptability to various materials during the cutting process. According to Mazak, the torch’s design facilitates quick, straightforward and economical maintenance, as it is possible to replace the protection window and lens swiftly on-site, eliminating the need for specialist equipment. This capability arrives courtesy of a specific cover that prevents any risk of contamination during the replacement process.

The OptiPlex Ez series utilises a fibre laser source that results in low power consumption and streamlined maintenance, while eliminating the requirement for laser gas. With configurations available in 3, 4 and 6 kW power options, OptiPlex Ez machines are suitable for diverse cutting requirements and can integrate into automated systems for higher operational efficiency.

Large front and side sliding doors optimise floor space, ensuring hassle-free material loading and unloading. The tilting and rotating CNC control panel allows operators to work at the front or side of the machine. Equipped with the new Mazatrol SmoothLx CNC control with 21.5-inch display and user-friendly HMI, the OptiPlex Ez series provides intuitive operational functions.
