Materials Matter: How to Set Up a Vibratory Bowl for Gear Finishing
The vibratory bowl is toroidal-shaped, consisting of a center hub surrounded by an OD wall. Direct drive machines have a motor and driveshaft set inside the center hub.
White Papers
Physical Characteristics of the Vibratory Bowl and How They Affect Processing Efficiency
Vibratory bowls are outfitted with hot-poured polyurethane liners and their durometer hardness is an oft-cited characteristic. But what is durometer hardness and how is it useful?

Materials Matter : The State of the Art of Wind Turbine Gearboxes
Much has been written here about the global growth in the wind turbine industry. Today, more than 341,320 wind turbines are operating worldwide. In particular, the number of offshore installations has exploded in the past seven years.
White Papers
Materials Matter: Nitriding’s “White Layer” and Isotropic Superfinishing
Developed in the early 20th century, nitriding has evolved into a standard process across many industrial applications. Often considered the simplest technique for case hardening, the process is commonplace in aircraft manufacturing, bearings, automotive components, turbine generation systems, and various industrial machineries.
White Papers
Repairing Wind Turbine Gears and Assemblies with Isotropic Superfinishing
As the wind turbine industry matures, the importance of operations and management (O&M) costs grows. In the early years of large kilowatt and small megawatt class wind turbines, pre-mature gearbox failure due to gear fatigue was very common and was a significant issue for wind turbine gearbox manufacturers, wind turbine OEM’s and owner-operators.
