LWI V Flexx Unixx III

This unit has been developed for areas where the laser work shop needs to be prepared for any type of job. Regardless of whether thousands of small pipes need to be welded or cut today and a three ton mould delivery tomorrow, the UNIxX III will fulfils any task with the highest precision.

The many software tools provided will ensure speedy and high precision processing.

The range of 700mm in the x axis and 400mm in the y axis enable you to process big components without the necessity of them being repositioned.

Small pieces with the weight up to 300kg can be processed on the working table aforementioned in UNIXX and the working position pivoted accordingly.

The positioning and height of the working table has been designed to level with a normal office chair to allow one to sit and work ergonomically, and provides enough legroom. The sturdy table tipped at a well positioned angle ensures that there are no obstacles in your way.

When working on very big pieces, the working table can simple be swivelled to the side to allow the component to be placed under the laser by forklift. The extended range length enables you to reach the area to be repaired quickly.

The head is equipped with a bracket allowing for rotation of the laser head and enables you to weld on edges and angles.

Teach in

Enables the handling of complicated geometries in four axis without complex programming. A small number of support points are hit once on the contour of the work piece in advance. The user can subsequently move the programmed welding line forward and backwards using the joystick and can also shift its position by offsetting the start point.
Schutzgas

Programmable shielding gas post-flooding

In order to eliminate the oxidation of the welded joint directly after it has been welded, the times during which the shielding gas ist still conducted on the welded joint following the welding can be individually set.
PWM

In the lower power range, which depends upon high stability, traditional lasers are inclinined toward a low „pulse to pulse stability“ and thus to a non-uniform welding result. The Pulse Width Modulation (PWM) gives a vastly more fine and stable coordination, as the internal energy supply here works in the area of the optimal output.
Pulse shaping

Free pulse shaping enables the setting and saving of all possible variations in the pulse process. Materials with different thermal coefficients of expansion thus show a clearly better welding behaviour - your laser´s area of application thus expands.
pulse distance synchronization

Provides a constant pulse overlapping through the dynamic synchronization of the pulse trigger with the axis movement. PDS ensures replicable welding results with different speeds and consistent, homogenous weld joints in all movement situations. Therefore, a higher operating speed can be reached.
On axis gas

On-axis shielding gas supply

A reliable on-axis shielding gas supply enables perfect welding even with highly-sensitive materials, such as titanium, for example.

The welded joint is always flooded with shielding gas under 90 degrees. This prevents the sort of shadow effects and swirling which occurs when a lateral gas supply is used.
Rotation Axis

Specially developed turning units increase the user value of your workstation. They incorporate all functions of CAN-Step control, available at the touch of a button, including pulse synchronization and „Teach in“ programming.

Additional features: • Swivel-mounted • Free implementation up to Ø40 mm • different chuck types, chucking range up to Ø 160 mm.
Display

Large display with backlighting

The large backlit display provides the user with a direct view of all the important operating parameters. Adjustment limits are visualized.

The adjustment of the parameters themselves takes place via the work chamber´s control elements.
Can Step

Precisely controls axis movements. This extends manual welding by its sophisticated automatic and programable functions. Touchscreen and Joystick terminals directly in your workspace provide a unique, simple control concept. Thanks to the completely integrated hardware, a separate computer is not needed.
Booster

Booster technology for long lamp lifespan and heightened pulse stability The booster enables you to further raise the „pulse to pulse stability“ and to lengthen the lifespan of the flash lamp. Shortly before the shoot, the simmer power is automatically increased, thus stabilizing the plasma in the lamp and increasing the electrode temperature. This leads to a substanitially more stable energy output of the laser, especially with low energy.
Beamtuning

Beam Tuning Set

The innovative Beam Tuning Set combined with booster technology guarantees a stable output even with very low pulse energies.

This is particulary beneficial when it comes to welding extremely small parts. The spot size can be reduced to 50 μm.

This feature is available as either a fixed installation or a manually connectable option.
3Point

You can process circular type contours by using the PCD function with the XY axis. The circular path is precisely defined through the teaching of only three support points. You do not need to know the center or the diameter; the position on the work piece is optional. You can move along the programmed course either forward or backward by using the joystick.

Integrated work table with aperture

The useful high load capacity work table can be revolved under the laser head. The plain-milled slot profile worktop can be rotated and is locked. Supports and worktops provide free lead through. This allows you to weld long work pieces smoothly.

Concept: Flexible use

The enormous traverse paths of the extension arm enable the processing of long welding lines and large surfaces without repeat clamping of the work piece, while the laser head stays flexible and can also be manually tilted. Suitable for the processing of small to very large work pieces.

Operating comfort

For an ergonomic and flexible workspace: Leg space and a manually adjustable head tilt provide the optimal conditions for the user. All operating elements are ergonomically attached closely to the working head. You have a direct view of all parameter settings.

CAN-Step: The intelligent axis control

Precisely controls axis movements. This extends manual welding by its sophisticated automatic and programable functions. Touchscreen and Joystick terminals directly in your workspace provide a unique, simple control concept. Thanks to the completely integrated hardware, a separate computer is not needed.
