Surface layer hardening
We also cure gears and geometries in the range between 500 mm and 8,000 mm — segmented even larger
Induction hardening or induction hardening is a special form of heat treatment in which metallic workpieces can be exposed within a very short time to a changing magnetic field, thereby heated and hardened by subsequent quenching.
In this very precise, non-contact hardening process, it is possible to harden only certain areas of a workpiece or the surface, without affecting the properties of the workpiece as a whole.
This form of surface hardening, depending on the material, the workpieces given a corresponding surface hardness at the desired locations at a relatively low delay.
Deutsche Großwälzlager GmbH is a specialist company certified to DIN EN ISO 9001: 2008. On our modern CNC-controlled induction hardening plant, we process large parts up to a diameter of 8 meters in the circulation feed process, as well as medium and small series in the feed process (rotating) for mechanical engineering.
Our own inductor manufacturing department allows us a high responsiveness even with special geometries of the workpieces, so that even complicated parts can be processed at short notice.
We cure with the latest technology. A consistent quality assurance with appropriate documentation by our quality management department is a matter of course.
Induction hardening also as core process in our slewing bearing production is secured and tested with different methods:
- Process simulation
- Testing and approval with separate test material
- Measurement with ultrasonic devices of the market leader Q‑Net
- Destructive testing, if necessary
