SUBLIME®
SUBLIME® – The coating that redefines service life in gear manufacturing
The SUBLIME® tool coating was developed for the special requirements in gear manufacturing. Especially when cutting internal and external gears in steel workpieces, long cutting paths and high cutting speeds are required. The SUBLIME® layer considerably reduces the wear of your gear cutting tools.
Up to 130% longer service life in the gear teeth
In tests with commercially available hobs, the new, innovative SUBLIME® coating was compared with other coatings. The results show increases in tool life of up to 130%.

Innovative layer architecture
SUBLIME® is produced in the PVD systems of voestalpine eifeler Vacotec GmbH and is based on AlCrN and AlTiN as coating materials. This combination produces an impact-resistant, temperature-resistant coating with optimum adhesion. Thanks to its layer architecture and elements, SUBLIME® achieves top wear resistance, even at the high temperatures that often occur in gear teeth.
