RDX1000 MACHINE FOR DEMANDING LASER MICRO-MACHINING

The RDX 1000 laser machine expands the portfolio of the RDX series from Pulsar Photonics with a system with which the highest demands in laser microprocessing can be met. The bigger sister of the RDX 500 allows next to the acceptance of larger laser beam sources (such as USP high-power lasers), especially the processing of larger workpieces up to dimensions of 450 mm x 600 mm . Thanks to the flexible integration of different processing heads from the system technology portfolio of Pulsar Photonics, but also of scanning systems such as polygon scanners and fixed optics, the machine different laser processes from the field of micromachining simply be covered. The outstanding property of the laser machine is the integration and use of measurement technology to increase the stability of laser processes. By measurement of process variables in laser processing such as power, beam position, temperature and vibrations, the condition of the system can be monitored at any time and, if necessary, the system can be adjusted (condition monitoring).

Topography sensors allow the results of the laser processing to be checked directly in the machine and thus to correct processing or to qualify the components directly in the machine.

The base of the machine frame is designed as a welded steel construction, all components of the laser beam guide are low-vibration and temperature-stable mounted on the granite / natural stone machine bed. The control technology of the laser system relies on modular field bus systems in the industrial standard. The modularity of the system design also allows the adaptation of handling systems for component feeding for series production.

Pulsar is addressing Photonics with the machine tool of the RDX 1000 series demanding users from research and development, but also from industrial individual parts and small series production.

Helical drilling optics for precision drilling

Image source: Fraunhofer ILT

Processing head for precision drilling with high aspect ratios. The 2-part processing head facilitates integration even in small-format and standardized laser machines. The third generation of the helical drilling optics used (patent DE102005047328B3, 2006 Fraunhofer ILT) enables the laser beam to rotate quickly on the drill circle path. At the same time, the laser beam is set in rotation and impresses with its optical translation and operation at moderate speeds. In combination with an XYZ axis system, all drilling geometries can be implemented or precision components can be cut.

Materials and applications:

  • Drilling & precision cuts
  • Smallest and ideally round holes with a diameter from 20 µm
  • Burr and beard-free cut edges, drill holes without edge removal

Photonic Vectors (CAM software)

Pulsar Photonics uses its own high-performance CAM solution to prepare machine and vector data (CAM data) for 2.5D laser processing PhotonicVectors . The software with a graphical user interface allows volume models to be loaded, which can then be broken down into layers, scan vectors and axis infeeds in line with the process. As a result, the user receives a finished job file that can be loaded directly into the PhotonicElements machine software and executed there. In addition to a large number of basic settings for 2.5D laser structuring, the following functions are suitable for your application:

  • Slicing: Decomposition of the volume model into individual layers. Input of the number of layers into which an ablation volume is to be divided in the z-direction
  • Hatching: Hatching of each layer with scan vectors. Input of the hatching with which a layer is to be filled; including hatching spacing, direction, randomization, etc.
  • Contouring: Edge cuts with parallel offset to the outer contour. Input of the edge cut with which the outer contour is to be worked out; including distance, number and position
  • Tiling / stitching: Automatic division of the target geometry into processing fields of variable sizes. Randomization of the processing fields for quality optimization in multi-layer processing.
  • Intelligent tracking: automatic (re) sorting of scan vectors to reduce jump times.
