Optics for remote processing

TRUMPF optics for remote processing

The programmable focusing optics from the PFO line are scanner optics for remote welding and cutting. Using two mirrors, the laser beam can be positioned in any specified position within the processing field or space, or be guided along any seam geometries. They can thus be welded without moving the workpiece or the focusing optics. Additionally, no shielding/assist gas is required.

Fast and precise

State-of-the-art, digitally controlled drives ensure a fast pace

Welding on the fly

Robot, laser and programmable focusing optics are synchronised and positioned precisely in real time

Large selection

In the PFO portfolio you will find a solution for every application, from the low-power to the high-power range.

Absolute process reliability

Increased process reliability and quality through an optional connection of intelligent sensor solutions.

Intuitive operation

Set up laser welding and cutting programs in an intuitive, mobile and quick way with the PFO SmartTeach app.

PFO SmartTeach saves you a great deal of time during setup, and the time needed may even be cut in half, depending on the component. You can get the PFO SmartTeach app for free in the Apple App Store.

The programmable focusing optics (PFO) from TRUMPF are especially well-suited for quick and reliable processing of large workpieces. The combination of robots and PFO brings together the best of both worlds: a large work area with excellent dynamics and precision, and a long focal length that allows large working distances from the workpiece.

Using two mirrors, the laser beam can be positioned in any specified position within the processing field or space, or guided along any desired contours. Since neither the workpiece nor the optics have to move, the PFO enables a high degree of productivity, while processing costs remain low and process results are reliable. "On the fly" processes can even be realised using a special control unit.

Programmable focusing optics PFO 1D

PFO 1D

The PFO 1D programmable focusing optics combine the best of both worlds: the robustness of industry-proven TRUMPF fixed optics and the scanner functionality of programmable focusing optics (PFO). The individually adjustable 1D wobbling movement of the laser beam means you benefit from utmost weld seam quality, both during heat conduction welding as well as during deep welding applications.

Laser: TruDisk
Max. laser power: 8 kW (cw)

Programmable focusing optics PFO 14

PFO 14 / PFO 20-2

The PFO 14 and PFO 20-2 programmable focusing optics are ideally suited for spot welding or path welding where high speeds are required. The 2D scanners function according to the pre-objective scanning principle. This allows them to reach all points in the scanner's processing space with high dynamics and consistent beam quality, at a near-constant working distance. You also benefit from easy focusing lens replacement, due to the fact that calibration data is saved in a storage device on the focusing lens. You can easily join complex components with multiple weld seams.

Lasers: TruDisk, TruDiode, TruFiber, TruMicro
Max. laser power: 300 W (TruDiode), 2000 W (TruDisk, TruFiber, TruMicro)

PFO 33-2

Use PFO 33-2 programmable focusing optics for spot welding or path welding with high demands on repositioning times. The 2D scanner works according to the pre-objective scanning principle as well. This means that you can reach all points in the scanner's processing space with high dynamics and consistent beam quality, at a near-constant working distance. You also benefit from easy focusing lens replacement, due to the fact that calibration data is saved in a storage device on the focusing lens. Optionally, these optics are also available with TRUMPF VisionLine image processing.

Lasers: TruDisk, TruMicro
Max. laser power: 8 kW (cw)

PFO 3D-2

The PFO 3D-2 programmable focusing optics constitute a 3D scanner which is also based on the pre-objective scanning principle. This allows all points in the scanner's processing space to be reached with high dynamics and consistent beam quality, at a variable working distance. All NC programmes are saved locally in the PFO, which also allows for operation without a PC. Optionally, the 3D scanner is also available with TRUMPF TruTops I-PFO offline simulation software, seam tracking with SeamLine Remote triangulation, and the CalibrationLine calibration tool.

I-PFO

The perfect software solution for laser welding when dealing with complex challenges. The TruTops I-PFO software makes it easier to set up and adjust complex tasks that need to be carried out with industrial robots and PFO 3D welding optics.

TruTops PFO

TruTops PFO is offline software for 2D and 3D programming of your PFO. You can define any paths, edges, or planes of objects created in the CAD editor or loaded from external sources as welding seams. You can simultaneously take into account clamping fixtures in order to optimise the welding sequence and therefore the processing time. The software makes it possible for you to program different wobble methods. You can use the network to connect TruTops PFO with TruControl.

TruTops I-PFO

To make the most of the advantages of intelligent remote processing, you can program the I-PFO with TruTops I-PFO. The offline 3D development tool determines the ideal process and optimises the path and speed. You can simultaneously take clamping fixtures into account in order to optimise the path of the robot and welding sequence, and therefore the processing time. The software also analyses the cycle time and presents it virtually.

Expand the PFO programmable focusing optics with a variety of innovative functions.

Integrated camera system for the PFO
Camera connection

Various cameras can be directly adapted to the PFO. A digital colour camera system enables the sharp detection of contours and edges, for instance. The software of the PFO supports camera operation by way of touchscreen, crosshairs that can be set digitally and the saving of images. Even in low light, the coaxial and therefore direction-independent lighting brings everything into perspective.

I-PFO

The intelligent PFO (I-PFO) recognises its own position in the work area of the robot, as well as the position and orientation of the processing points. Based on information on the current robot movement, the I-PFO independently starts processing as soon as it is possible in terms of geometry and process technology. Remote processing "on-the-fly" is thereby possible, which greatly reduces both the positioning time of the robot and the cycle times in your production operations.

Functional principle of the PFO SmartTeach application
PFO SmartTeach

PFO SmartTeach is an application for your programmable focusing optics in the PFO series. It makes creating and setting up laser welding and cutting programs easier. The camera installed on the C-mount of the optics transmits the live image to the app. This enables convenient teaching directly at the component. If you want to create and teach in PFO geometries, you can do this by way of intuitive gesture operation on a tablet PC.

Reduction in contamination and spatter thanks to the crossjet option
Crossjet

Crossjet is a compressed air flow that runs orthogonally to the laser beam. It diverts contamination and spatter and thereby extends the service life of the protective glass. The laser process becomes more robust.
