Transforming the Way Material is Cut

LARGE PLATE LASER CUTTING
ESAB Cutting Systems (Florence, SC), an industry leader in plasma and oxyfuel cutting, has joined forces with TRUMPF to produce the Alpharex large plate laser cutting machine. With working widths of up to 17 ft (5 m), the Alpharex has no theoretical restriction in working length. The specially designed laser resonator is mounted on the machine and moves with the machine in the longitudinal direction. In the transverse direction, the beam is delivered by flying optics to the workpiece. This design feature eliminates beam divergence along the longitudinal axis, and ensures that the laser intensity and the cut quality remain constant over the full work space.

The Alpharex laser cutting machine is fitted with a CO₂ laser system supplied by TRUMPF. The TLF-turbo lasers, featuring power selections of 3.2 up to 6 kW, guarantee high precision cutting of carbon steel up to 1.0 in (25 mm) thick. The Alpharex may also be configured with a laser bevel head for cutting up to 450 bevels on parts. Specifications are as follows:

Please note that specifications are subject to change without notice. Please contact ESAB for the most current specifications, numerical control, and available equipment.

The laser process is fully controlled and automated through Vision CNC. All laser parameters, such as power, frequency, piercing routines, gas pressures, and cutting height, are set automatically by the CNC. The Vision CNC also controls the adaptive optics which provides autofocus and also ensures consistent beam quality. Other features on the Alpharex include:

• Large working area increases plate utilization when nesting and cutting large parts.
• Class 1 Laser protection with the optional PRO-LAS enclosure.
• Optional Laser Contour Beveling up to 450 facilitates welding preparation.
• Production cutting to 1 in carbon steel, 5/8 in stainless steel, ½ in aluminum.
• Cutting and marking with the same laser tool.
• Video camera monitoring of the process at the operator’s console.
• Complete process control and automation through Vision CNC.
• Oversized AC Drives for high dynamic response and excellent positioning accuracy.
• CNC controlled auto-focus using adaptive optics for highest reliability.
• Pierce detect and cut loss detection.
• Safety light barriers front and rear.

LASER MARKING SYSTEMS

MOBILITY IN LASER MARKING
The TruMark 5010 Mobile Marker, an innovative portable laser marking unit from TRUMPF Inc. (Farmington, CT) features a compact and handheld marking head. The operator simply moves the laser marking unit to the work piece, eliminating the need to move the part, and intelligent sensors help guarantee the entire process is conducted safely and accurately.

Unlike conventional methods, the laser marking process is achieved without special tooling or consumables. As a tool, the laser is extremely flexible and is capable of marking identifying characters and images including barcodes, variable text, and data matrix codes. The TruMark 5010 Mobile Marker can also handle simple cleaning tasks and can prepare small areas for processing.

A fiber laser operating in the infrared spectrum forms the heart of this marking system. A laser light cable guides the beam from a mobile frame which holds the laser, safety controls and suction system, to the scanner unit at the workpiece. When the operator positions the TruMark 5010 Mobile Marker, a vacuum is created which hermetically seals any gap between the machine and the component. If the processing head is not properly positioned, sensors prevent the laser from emitting its beam. This guarantees that the operator cannot inadvertently start the laser.

The Mobile Marker also features an integrated vacuum unit which removes any vapors or materials dislodged during the marking process. In addition, the unit’s compact design and low weight permit not only straightforward manual operation, but also integration into assembly lines.

Fast and flexible describe the TruMark 5020. High pulse frequencies and superior pulse-to-pulse stability make this fiber laser marker the ideal solution for metal or plastic applications where high speed and superior edge quality are required. Its highly dynamic scanner module is able to convert pulse frequencies of up to 1 megahertz into a correspondingly high processing speed. In turn, thanks to MOFPA technology (Master Oscillator Fiber Power Amplifier), the pulse duration of the TruMark 5020 can be adjusted so that laser processing is perfectly adapted to the application. In addition, the laser’s focus point adjusts to the different component heights. The TruMark 5020 shows special strength in marking metal by delivering high quality customized marking or engraving in short processing times.

The TruMark 5020 is designed with a special focus on laser safety and features a fiber protection hose with a mechanical lock to prevent the laser beam from discharging between two marking procedures.

Telediagnostics makes it possible to maintain the fiber marking laser remotely with comfort and security. For this purpose, the TruMark 5020 comes with integrated laser power measurement and laser power calibration – features that have been proven to maintain laser marking consistency.

ENHANCED LASER MARKER SOFTWARE
Miyachi America Corporation (Monrovia, CA), a leading manufacturer of welding, marking, cutting and micro machining equipment and systems, has updated their LMF series’ laser marker  software and control card for improved graphic file editing (GFE) and enhanced functionality for production line operation. The updated software and control card allows for the control of up to 4 axes of motion without the need for a dedicated PC, saving space and simplifying integration into production lines.

The new card also features an improved ability to mark QR codes and TrueType fonts. The improved GFE enables users to size, shape and edit graphic files such as .dxf and .dwg within the marking software’s graphical user interface giving users the freedom to adjust node locations, close paths, and more directly modify graphic files without adding third-party software. These new features are now standard in all new LMF series markers. Existing markers may be upgraded by Miyachi America service personnel, in the field.  Contact the company to schedule a field service visit.

CAMERA REGISTRATION SYSTEM
Kern Laser Systems (Wadena, MN) is excited to announce the addition of k-vision to their current line of laser systems. The optional k-vision package is a fully integrated hardware and software solution that allows for accurate cutting of printed materials. This process starts with a nozzle mounted camera which automatically measures the dimensions between registration marks on printed materials. The system then uses these measurements and the registration marks of the original cutting file to compensate for distortion and rotation. The slight adjustments that k-vision makes to the cutting file results in a perfectly matched cutout in the material being processed. The entire camera system can be easily removed and stored in a protective box when not in use. The k-vision option is compatible with the entire Kern laser system lineup.
