Laser turning
In order to prevent undesirable friction processes or rapid wear, the microscopic components of high quality watches must have optimal surface properties. This also applies to the pivots of the various shafts in the movement. If their quality suffers, then this would quickly lead to the clock noticably gaining or loosing time. These components are traditionally manufactured using... Read more

In order to prevent undesirable friction processes or rapid wear, the microscopic components of high quality watches must have optimal surface properties. This also applies to the pivots of the various shafts in the movement. If their quality suffers, then this would quickly lead to the clock noticably gaining or loosing time. These components are traditionally manufactured using a mechanical turning process. However, chip formation, heat effects and tool wear lead to large variances in quality. In addition, conventional lathes aren't always able to reliably reproduce the often challenging geometries, for example at the transitions... Read more

LASER DRILLING
We have long-standing experience with the production of micro laser drilling. We work hard materials which are hardly to be worked on like hardened steel, hard metal, ceramics and diamond.
But we are also able to drill standard materials like high-grade steel, copper alloys and plastics very exactly.
MICRO CUTTING
Special trepanning optics allow for right-angled cuts in the µm range without post-processing.
With the GFH laser machining system, ferrous and non-ferrous metals as well as non-metallic materials up to a thickness of 1 mm can be cut. The speed primarily depends on the desired contour and surface quality.
ENGRAVING
The laser offers a highly flexible tool for the manufacturing of deep engraving. Removal is performed on the basis of conventional CAD datasets, allowing programs to be created quickly. Since a tool with a negative of the geometry is not required (as is the case with form EDM), this manufacturing step is eliminated and the laser can be used economically even for small batches or frequently changing geometries.
In addition to the construction of micro laser conditioning attachments and the development of the conditioning processes, the GFH offers the job shop manufacturing of specific components.
LASER TURNING
With a special trepanning optics, a thin laser spot with up to 25 microns is created and will be lead to the rotating work piece which brings it to the required form. Since in this case neither a mechanical nor a relevant thermal influence is acting on the material, even the smallest structures can be created precisely and with a surface roughness of <0,2 microns.

The newly developed GL.smart laser system with up to 16 simultaneous axes is the all-purpose weapon for laser micromachining. Thus, the smallest machine in the GL series not only offers the option of combination machining of laser turning and 5-axis machining, but also an output increase through the possibility of double machining
The GL.compact laser micro-processing machine features an extremely compact design and great flexibility. With highly modern beam generators (fs and ps lasers) and the ability to integrate all available options this machine is suitable for most applications.
The GL.compact II laser micromachining system is an innovative new development offering the possibility of 5-axis simultaneous machining. The special precision, stability and accuracy of the machine is ensured not only by a completely new cooling concept, but also by the newly developed axis kinematics. In addition to its extremely compact design and high flexibility, the GL.compact II offers a greater variety of components due to its more extensive working range.
Under the name GL.evo, GFH is presenting a 3 or 5 axis machine tool for industrial laser micro machining. The machine design harmonizes the requirements for precise (< 1µm) and dynamic (20m/s²) kinematics with the requirements of short-pulse laser technology.
The field of applications ranges from ablation and coating removal processes to engravings and micro drilling with high aspect ratios. For the mentioned tasks different modules are optionally available.
The GL.ultra offers a wide range of laser processing possibilities with automated solutions, maximum laser-on-time and thus maximum output at short cycle times. It was developed to enable several machining steps on a component with only one clamping set-up. In an appropriate ratio to the machining versatility, hardware and installation surface were saved in order to reduce the required installation space of the machine. The integration of two 5-axis processing stations in one machine, as well as the possibility of integrating several laser systems in parallel, guarantee the customer the highest level of investment security.
