New TLH Series 5-axis laser cutting system offers high cutting speeds and versatility

Komatsu America—Laser Group, Novi, MI, has introduced its fastest performing system yet with the TLH Series 5-axis, three dimensional Komatsu Fiber Laser processing machine. The TLH Series, of which there are three models, provides cutting speeds to 1,181 in/min (30,000mm/min)and features fiber optic beam delivery with 2 and 3 kW power options.

The series is ideal for hot stamping operations and has shown itself to be more accurate than other operations such as robotic laser systems. Further, the series is ideal for any production application that requires high speed cutting of thin gage mild steel, aluminum or stainless steelÉworking best with materials less than 3/8″ thick. These highly rigid machines allow operator access from the opening of one side of the machine for optimal accessibility. The feature provides dramatically superior operability and workability.

The series provides X, Y and Z axis travel up to 177 in. (4500mm), 45 in. (1150mm) and 20 in. (500mm) respectively with positioning and cutting accuracy 0.0015″/19.68″ (0.04mm/500mm) Combined with its controllable optical head angles of +720 degrees on the C axis and rotation of +/-135 degrees, on the A axis, the TLH can operate in virtually all cutting applications.

The series can be modified with two integral pallet changers or a large indexing table (up to 120 in.) for increased flexibility and production. The system uses a Windows® operating environment, non-contact gap sensor technology, controllable optical head angles, and operator friendly joystick and hand-held pendant—along with a teach mode that all help to make complex cutting simple.

The TLH Series was developed to provide, through simple programming and operation of integrated motion and laser systems, high-productivity performance in cutting complex parts, to generate intricate beam paths and to adapt laser parameters to various cutting requirements.

The TLH also provides precision cutting, established first on its cantilever-style construction and solid base that are the foundation of its operating accuracies. The construction features are matched with AC servo motor drives, ball screw feeds and linear ball guide mechanisms that provide movement tolerances of +0.0019 in. per 19.6 in. of travel distance (+0.05mm per 500mm). To assure consistent beam penetration despite contours and form irregularities, the TLH’s non-contact sensor provides rapid response to changes in the gap between cutting needle and material to maintain the beam’s optimum focus.

The TLH Series programs can be prepared either by using the teaching playback system or by using NC data made with an optional automatic programming system and corrected by the teaching playback system if necessary. The teaching mode allows for settings for on/off laser beam, pulse rate, laser power, cutting speed and other parameters. In addition, the control incorporates memory storage for multiple part programs and includes integral subroutines such as linear, circular and spline interpolations, copying and mirror shaping, pattern downloading, circular cutting and corner rounding from center point definition, scheduling parts and operations for unattended production.

Laser power options are available with up to 5.0kW output that, when coupled with flying optics and features such as a non-contact gap sensor, side gas assist, and auto focus, assure cutting integrity. An automatic pierce sensor and retry function are also available.

Complementing the series’ speed and powerful laser output are two model choices with work envelopes that fit a majority of application needs. The TLZ-408 provides a 98″ x 49″ inch (2,500mm x 1,250mm) cutting stroke; the TLZ-510 model has 122″ by 61″ (3,100mm x 1,550mm) axis movements, and both models have a 100mm (4″) vertical stroke of the optical head.

The TLZ Series provides tight tolerances with positioning accuracy of +.002″ per 20″ of travel (+.05mm over 500mm).

Controlling this performance is a single but advanced CNC unit that features one-touch function and programming of most operations, eliminating multi-key data entering and helping to error proof setup procedures. The control programs, directs and monitors all machine functions, positioning, laser output, and process parameters. The CNC is matched with NTC’s innovative laser processing software that has built-in subroutines that include calculations and functions for circle, arc and linear interpolation, mirror imaging, an extensive cutting parameter library as well as scaling, automatic skew compensation, part program storage recall and a comprehensive self-diagnostics package.

Performance is heightened with features such as the extra wide, non-jamming conveyor that keeps trimming scrap moving, the power assist work piece lifter along with open access helping to make loading and unloading easier, and the dual pallet changer that moves both pallets simultaneously for faster changeover. Auxiliary material handling options are available for the TLZ systems, including multiple level storage shelves/loaders, that permit automated, unattended operation.

In addition to the TLZ Series ultra high speed systems, NTC America’s lineup of laser products includes the TLV Series 2-dimensional, 3-axis hybrid systems, the TLX Series 3- axis gantry-design machines for large (up to 15′ x 100′) workpieces, and the TLM Series of high power CO2 machines with bridge-type construction and 5-axis control for precision cutting and welding of 3-dimensional workpieces.

Wide Ranging Performance in a 3-Axis Laser Cutting System

December 4, 2015

When the challenge is to cut large plates, or thick stock in a variety of alloys, and routinely fabricate intricate, complex shapes…the solution from NTC America’s Laser Group (Novi, MI) is the TLX Series of gantry-type, 3-axis CO2 laser systems for two-dimensional cutting applications. The TLX machines are a combination of a rugged construction and high-powered laser energy that produces a cutting system tough enough for the harshest manufacturing environments. Yet, the TLX Series also features exceptional precision, and speed along with an operational package that blends all of its productivity performance and power into units that are simplistic in their programming, setup and operation.

In addition to meeting high performance requirements, including fast processing times, accuracy, reliability from its solid machine tool construction, the TLX Series has been reconfigured with a design that places the laser and chiller components on the system’s gantry. This concept provides a smaller footprint and shorter beam path that results in space and labor savings, increased flexibility and greater edge quality in cutting operations.

The TLX systems are, first and foremost, built for heavy duty, rigorous fabrication jobs. Within the series are four standard gantry-style machines that provide working strokes from 10.5′ x 46.25′ (3,200mm x 14,100mm) up to a massive 15′ by 100′ (4,550mm x 30,500mm), and with approximately 8″ of vertical Z-axis travel. A fifth unit in the series is a cantilever model that provides an envelope of 8.5′ x 20.3′ working strokes.

The TLX Series has three power options available including 3.3kW, 4.0kW, 5.0kW and 6.0kW produced by dependable fast axial flow, DC excitation lasers that deliver consistent energy strength and beam quality.

The TLX lasers provide high-speed performance for short cycle times and fast throughput. Rapid feed rates of up to 1,181″ (30,000mm) per minute, X & Y axes, and to 393″ (10,000mm) for the Z-axis position the beam quickly, while cutting speeds of up to 393″ (10,000mm) per minute are possible. These speed ranges are coupled with precision motion that spans just +0.004″ per 12″ (+0.1mm per 300mm) of travel. This accuracy is the result of AC servo motors, linear guides and rack and pinion systems built for the heaviest-duty models that give each model high strength and rigidity throughout the full range of travel. The TLX lasers also have an exclusive drive system that isolates incidental motion from the beam delivery system to provide virtually vibration-free optics for precision cutting at high speeds.

The TLX models incorporate a fast-response gap sensor to monitor optics-to-material distances and an auto focus option that can automatically adjust the laser focal point to compensate for various material thickness while maintaining optimum pierce and cutting quality. Additional features include a Fanuc CNC controller that enables instantaneous and simultaneous movements of all three axes to generate smooth cutting action through a full range of part geometries and shapes. The control functions are balanced with NTC-developed, laser specific software with built-in subroutines and cutting parameter library for circle, arc and linear interpolation, to simplify mirror imaging and scaling, provide automatic skew compensation, part program storage and recall, and comprehensive diagnostics.

In addition to the TLX Series of laser cutting systems, NTC America’s lineup of laser products includes the TLZ Series of 2-dimensional, 3-axis systems with flying optics, the TLV Series 3-axis hybrid machines for large, wide workpieces, and the TLM Series of high power CO2 machines with bridge-type construction and 5-axis control for precision cutting and welding of 3-dimensional workpieces.

The five models of TLV lasers incorporate hybrid technology, allowing both the machine and material to move at the same time during the cut, providing a more stable machine operating platform and more accurate cuts, independent of the system’s size or the workpiece’s bulk. Plus, with five laser power options starting at 2.5kW and working up to 6.0kW, these laser cutting systems deliver deep penetrating cuts to 1″ thick. And, the TLV bridge-style machines incorporate a wide open design that offers access from three sides to facilitate material loading, though its compact configuration typically requires less floor space than similar capacity machines.

Among the five sizes of TLV units are processing centers that begin with 51″ x 49″ (1,300mm x 1,250mm) and range up to a 246″ x 86″ (6,250mm x 2,200mm) X-Y work envelope…with 12″ (300mm) Z-axis vertical stroke. The TLV systems feature drives consisting of AC servo motors, plus the hybrid construction that requires ball screw and linear ball guide mechanisms that, as opposed to conventional rack and pinion mechanisms on the non-hybrid type machines, are better suited for accuracy and stability.

The TLV’s five power options encompass a full range that includes 2.5, 3.0, 4.0, 5.0 and 6.0kW, to match application requirements. The systems use dependable fast axial flow, DC excitation lasers for consistent and targeted power output to assure full penetration and clean cutting action.

The TLV systems offer a high level of cutting productivity with a rapid feed rate of up to 1,181″ (30,000mm) per minute in both the X and Y axes, and up to 787″ (20,000mm) for the Z-axis. That Series also features feed rates of up to 787″ (20,000mm) per minute. Yet, given those sizes, power options and speeds and feeds, these lasers produce precision with positioning accuracy as close as +0.0005″ per 12″ (+0.01mm per 300mm).

The performance specifications of the TLV Series are further expanded with an array of features and options that introduce flexibility, ease of operation and automation into the mix. The series offers a fast-response gap sensor to monitor optics-to-material distance for optimimum cutting performance. The auto-focus option allows focal point adjustments to be made on-th-fly during cutting to further enhance the cut quality on thicker or irregular materials. To maximize loading and unloading efficiency, the TLV units provide automatic stock clamping and work lift mechanism as standard accessories; and for its large material handling capacity, a wider scrap-handling conveyor design that eliminates jamming and downtime. Plus, a centralized lubrication system helps lower maintenance requirements while a telescoping cover protects X-axis motion guides from contaminates.

The laser cutting systems incorporate a Fanuc controller and NTC-developed laser cutting software that synchronize machine motion with beam delivery to optimize performance, resulting in smooth cutting action and sharp, clean edges for complex and simple part shapes alike. The interactive software features subroutines, calculations, functions and a cutting parameters library that simplifies circle, arc and linear interpolation, mirror imaging, scaling, automatic skew compensation, and part program storage/recall for fast setups. A comprehensive diagnostics monitoring system lessens troubleshooting procedures to minimize downtime.

A broad range of options and auxiliary equipment from NTC America expand the versatility, productivity and operating economies of the TLV laser series. Depending upon application requirements, various system and cell automation combinations are available; including multiple level stock shelves, part offloading and storage, automatic focus and gas assist control, and material staging pre-load tables. With the sophisticated level of CNC control and software, dependable laser performance, rugged construction, and precision, even to the assurance of a non-jamming conveyor, these automation features allow the TLV’s to operate with minimal attention or totally unattended for extended periods.

In addition to the TLV Series of laser cutting systems, NTC America’s lineup of laser products includes the TLZ Series 2-dimensional, 3-axis systems with flying optics, the TLX Series 3-axis gantry-design machines for large (up to 15′ x 100′) workpieces, and the TLM Series high power CO2 machines with bridge-type construction and 5-axis control for precision cutting and welding of 3-dimensional workpieces.
