Tappet with half of a hair’s diameter
With the laser turning process neither a mechanical force nor relevant thermical influences have an impact on the material and this is why tappets with very small diameters and a good surface quality can be produced. The ejector in the picture has a length of 9mm and has been produced in a clamping process which is made of carbide and with a tappet of 40µm.

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.
MODIFICATION
Cleaving refers to the local modification of transparent workpieces like glass, fused silica or sapphire in order to release material along the introduced modification in a subsequent process. Advantages of this method over conventional mechanical processes exist in a micro structure modifi-cation in the complete volume of the material. This allows crack formation to be controlled in all spa-tial directions so that a homogeneous and vertical fracture edge with low roughness (Ra <0.5 µm) is generated. In this way arched fractures can also be achieved.

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.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.eco machine is based on the Trumpf laser marking station (TMS 5000). This marking station is already optimized for ergonomic and high efficient machining in 2D. Now all existing and new customers can use the well-known TMS system also for 3D machining.
GFH powered the TMS with their control unit and user interface developed for multi axis laser machining. This control unit allows to import 3D CAD files and to machine a defined 3-dimensional geometry layer by layer into the work piece additionally to all known 2D-marking operations.
