Comparison of Zinc-Containing and Zinc-Free Hydraulic Packages Using Severe Laboratory Performance Tests

摘要

Ever increasing demands on productivity, performance, worker's safety, as well as realization of total cost management lead to new and higher requirements placed on industrial lubricants. Higher machining speeds and new processes may cause much more thermal stress to the whole lubricating system. The paper will focus on comparison of traditional and modern hydraulic additive technology, considering highly refined base oils, compatibility of additive systems as well as widely used specification requirements.
