hardening as a service (job shop hardening)

Your ticket to the technology of laser hardening

		technology consultung for laser material processing with high power diode laser versatile usability in mechanical engineering, mould- and tool making high hardeness and ductile material core low distortion hardening of function surfaces and freeforms continuous camera based laser power control quality control with simultaneous documentation during the hardening process Alternatively laser hardening of your parts in our job-shop in Dresden.

special: hardening at your company

The newest service we provide is to harden your parts in your company.
This is interesting if you have big parts or parts which have to stay in the machine while removing causes a complex repositioning.
Also you avoid mounting/unmounting time and work.
The part is ready to use directly after hardening process. (a little oversize caused by laser hardening)
This procedure avoids downtime caused by transport - and not to be forgotten the risk of transport damages.

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.
