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?
White Papers
Measuring Tooth Flank Roughness
Gear performance has continuously increased over the past two decades. Improvements in metals, heat treatments, geometry, and lubrication are just a few of the sources of these improvements.
Technical Papers
Surface Treatment of Powder-Bed Fusion Additive Manufactured Metals for Improved Fatigue Life
High-cycle fatigue (HCF) tests were conducted on samples fabricated by two powder-bed additive manufacturing techniques.

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.

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.
