GPA comprises eight companies that produce a broad range of plasma, laser and waterjet cutting machines. Its latest CNC laser cutting machine, Speed Cut, can cut a variety of metals of various thicknesses in its work area of 1.5 by 3 m at speeds to 120 m/min. with positioning accuracy of 40 microns. Doing the work: a 2-kW IPG Photonics solid-state ytterbium fiber laser system, with a Precitec LightCutter 2.0 cutting head. This cutting head features automated motor-driven adjustment of the axial focus position, can handle acceleration rates to 3 g and covers a focus-position range of 23 mm.

A Num Flexium+ 8 CNC system controls all cutting-head positioning functions. All four machine axes are driven by Num high-torque BPX servomotors controlled by NumDrive X digital servo drives. The Y1 and Y2 gantry axes are equipped with 9.8-Nm motors, while the X and Z axes feature smaller 2.7- and 1.4-Nm motors, respectively. Num’s Flexium Tool commissioning software allows the Y1/Y2 axes to be tuned while the synchronization is active, thus maximizing performance and precision, according to Num officials. 

By capitalizing on the Dynamic Operator function in Num’s Flexium software, which enables event-driven machine cycles to be integrated into the real-time CNC kernel, Speed Cut users reportedly benefit from an automated dynamic height-control system that accommodates rapid cutting. The system interprets data from the machine’s cutting-head-height sensor and uses it to rapidly adjust proportional-integral-derivative loop parameters in the Z-axis servo drive. The height sensor also is employed to facilitate an automatic sheet-detection routine. This determines the workpiece’s dimensions, zero and angular offset, further simplifying the machine’s operation.

“We partnered with Num mainly because of its open-architecture CNC platform and its willingness to actively participate in joint development projects,” says Omar Sandoval, GPA owner and CEO.

Says Steven Schilling, Num Corp. managing director: “In addition to the real-time adaptive height-control and sheet-detection systems, the customized version of Numcut software that we are providing (for this machine) features a user library of material cutting conditions. It is preloaded by GPA with the optimal laser power levels, cutting speeds, etc., as a function of material type and thickness. The provision of this library will further add to the machine’s productivity and cutting accuracy.”

20-kW Laser for 24/7 Use

Eagle-FiberEagle Fiber Laser, a Power-Tech brand, has released what it claims to be the world’s first 20-kW fiber laser cutting machine, able to cut 0.75-in.-thick steel at 120 to 160 in./min. and providing reliability for 24/7 operation. 

The key to mastering such high laser power: the company’s eVa cutting head. With contamination from external sources or motorized motion of lenses representing the most common cause of optical failure, the eVa cutting head eliminates these contaminants to significantly extend head life, even when operating at 20-kW power. The machine, with its 6-g acceleration, also offers extremely high-speed cutting of thin sheet.

Fairmount Machinery distributes Eagle laser cutting machines in the United States.

New Dust Collector Optimized for Fiber Laser Cutting

RoboVent-SenturionThe faster cutting speeds of fiber laser machines create new challenges for laser cutting dust control, leading RoboVent to develop the Senturion, optimized for the volume and type of dust produced by fiber laser cutting.  Senturion addresses the challenges of fiber laser cutting dust collection with several adaptations, including a powerful and efficient motor-blower combination to ensure adequate airflow for laser cutting applications. Also, a lower air-to-cloth ratio (more filter media per ft.3/min. of air) handles large volumes of dust, and an advanced pulsing system prevents dust from becoming embedded in the filter media. The RoboVent Pleatlock filters used with the Senturion offer more filter media to capture more dust with less loading. Senturion also comes standard with RoboVent’s touchscreen control system and SafeSensor particulate monitor, which detects leaks past the filter and shuts the collector down if a leak is detected. The rugged, powerful plug-and-play system is designed to keep up with the demands of fiber laser dust collection in high-production manufacturing facilities.  

“Fiber lasers create higher loads of very fine particulate, which creates challenges for the fume collection industry,” says Rick Kreczmer, president of RoboVent. “Senturion has been designed to handle the high cutting speeds and rapid filter loading inherent to fiber lasers, so they deliver better performance for end users.” 

Gantry-Style Large Format Laser Cutting Machine

LVD-Large-FormatLVD Strippit, now branded as LVD North America in the United States, Canada and Mexico (see below), has launched the Taurus FL, a large-format gantry-style fiber laser cutting machine engineered for extra-large sheet metal cutting. It features a unique modular design, with machine size beginning at a 39-ft. bed length and expandable in increments of 6.5 ft. to a maximum bed length of 131 ft. The large format allows the cutting of a diverse range of parts, efficiently nested, to increase productivity and optimize material usage. The machine comes with a 6-, 8- or 10-kW fiber laser source.

Taurus FL enables flexibility to process extra-large sheets or multiple sheets, and handle varying batch sizes, shapes and material types. It accommodates workpieces in widths to 10.8 ft. and thicknesses to 1.18 in. Large parts can be processed without repositioning while multiple smaller workpieces can be positioned on the cutting table and processed in continuous fashion, without interruption. Parts can be cut on one section of the table, while loaded/offloaded on another, to optimize uptime. The Taurus FL also provides the option of beveling cutting or 2.5D cutting at angles to 45 deg.

The Taurus FL offers eased access, as only the gantry features an enclosure, not the complete machine, and the cutting zone has a detachable front panel, providing access for maintenance. The machine requires no special foundation. And, the mechanical design and drive system reportedly ensure high machine dynamics in large-format cutting.

An operator has use of two touch panels for access to the control at all times, with a handheld control unit allowing the operator to safely move all axes in manual mode for machine setup or to load the nozzle changer. A camera located inside the cutting zone and a monitor on the operator console allow continuous process monitoring. 

An optional automatic nozzle changer increases machine uptime and throughput. The unit has storage for 30 nozzles in a turret-style holder positioned close to the cutting head. The nozzle changer features an integrated camera that checks nozzle alignment, size and condition. It offers automatic calibration of the capacitive height sensing and nozzle cleaning after a preset number of piercings. 

Optional CadMan-L software includes automated functions to simplify programming and offers advanced nesting, collision avoidance, on-the-fly piercing and cutting, and process parameter tables to realize the machine’s full potential.

Also, Belgium-based LVD, a manufacturer of sheet metal working equipment including laser cutting systems, punch presses, press brakes, shears and automation systems, has rebranded the LVD Strippit brand in North America. The new name, LVD North America, reflects alignment with the broader LVD Group organization, say company officials, and helps unify the LVD brand across its 47 global subsidiaries.  The Strippit, Inc. engineering and manufacturing facility in Akron, NY, will become an independent production facility for the LVD Group, serving all markets worldwide. As such, the 250,000-sq.-ft. facility will manufacture a broader range of LVD products to support global sales.  Sylvain Lefebvre will serve as president of LVD North America; Elizabeth Victor is vice president sales and marketing; Mathieu Vanbraekel is vice president customer service.
