Comparison of Dynamic Characteristics Between Grease-Lubricated and Oil-Air-Lubricated Spindles
International Journal of Automation TechnologyOil-air lubrication is commonly employed in rolling bearings for high-speed spindles in machining centers. However, grease-lubricated spindles which consume less lubricant and air have recently gained attention. This study evaluates the lubrication condition of a spindle based on its dynamic characteristics through contactless dynamic spindle testing ...

Development of an oil-air lubrication system with a piezoelectric nozzle for machine tool spindles.
JSME international journal. Ser. 3, Vibration, control engineering, engineering for industry, 1988 Oil-air lubrication is one of the effective lubrication methods for the high-speed spindle of machine tools. However, the oil supply rate to the bearing fluctuates remarkably due to the intermittent oil supply from the oil-air mixing valves. In this study, a new oil-air mixing equipment is developed by applying the piezoelectric nozzle which has been ...

Control of Bacterial Attachment on Macroporous PDMS/Paraffin SLIPS With Varying Lubricant Viscosity
Advanced Materials Interfaces, EarlyView.Slippery liquid‐infused porous surfaces (SLIPS) prepared from macroporous PDMS, infused with medical‐grade paraffins, were systematically investigated regarding the correlation of viscosity, surface corrugation, bulk porosity, and bacterial resistance. Substrate porosity was found to dominate lubricant stabilization and the antifouling activity.
