Hardening

As the only Danish gear wheel factory Niebuhr Gears has its own internal hardening facilities. Our case hardening ovens are in the middle of the production line, to follow our LEAN flow principles. In our ovens, we can case harden items up to 1.2 m3. For larger gear Niebuhr Gears has 3 EMA induction hardening machines to harden gears up to Ø5000mm. For other hardening methods and items that are beyond our size capabilities, we have good agreements with external hardening suppliers.
