High Performance Lightweight Vibenite® Gear Hob
Benefit: Improved Performance, Weight Saving
Main Forming Process: Additive Manufacturing
End Use Sector: Automotive
Material: HSS


VBN Components has developed the additive manufactured wear resistant material Vibenite® 60 and tested this in a number of gear hobs at Volvo Powertrain, Sweden. In the tests, the hard and heat resistant material performed very well resulting in twice the lifetime and also the possibility for running with double feed in hobbing. The possibility to build lightweight structures resulted in a weight reduction of 40% of these heavy tools, from 15 to 9 kg.
