Technology - Laserhardening
| The surface hardening with high power diode laser (short laser hardening and laser-beam hardening) is increasingly used in industrial manufacturing and toolmaking.
The laser hardening is a process in which the energy input takes place by means of radiation directly to the component surface. The laser beam heats short term and localized the top portion of the workpiece up to the austenitizing temperature of the material used. This leads to a homogenization of the carbon distribution and thus to a spread of a front of austenitization in the material.
Depending on the material used, the austenitizing temperature is about 900 ° C to 1400 ° C and time to temperature at about 3 s to 10 s.

SKM DCAM 5
DCAM 5 is a standard CAD/CAM software,
that was extended with modules for generating robot programs.
- simple generation of robot programs without programming knowledge
- robot program is nearly ready before part is delivered (if the 3d data was sent before)

Laser Power Control
|
|
|
|
|
|
The laser power control consists of the temperature measuring system "E-MAqS" and the control software "LompocPro". This combination results in an uniform hardness track in face of permanently changing geometry of the part. Melted edges and drilling holes will be avoided.
For a short time it is possible to control laser cladding processes.

Scannersystem
|
 |
Fixe Optiken erreichen bei großen Werkzeugen ihre Grenzen, wenn man variable Spurbreiten benötigt.
Mit dem Scannersystem "LASSY" vom Fraunhofer Institut für Werkstoff- und Strahltechnik (IWS) ist es möglich, während des Prozesses variable Spurbreiten zu erzeugen. Zusätzlich kann man die Leistungsverteilung über die gesamte Scanbreite einstellen. |
