Up until recently, semi-synthetic fluids were considered the newest in metalworking fluid technology. They offered superior performance to their water-based predecessors, emulsifiable (soluble) and true solution synthetics. However, in recent years, a new type of hybrid formulation has emerged offering enhanced performance. These formulations include an oil-like component that is not mineral oil! The machining performance is that of an emulsifiable (soluble), but with the fluid life, corrosion protection, and cooling of a semi-synthetic and synthetic.
Hybrid semi-synthetic fluids are ideal for aerospace machining as they can deliver the lubrication required for the exotic alloys used in this market space while also providing the cooling necessary to keep up with the fast-paced machining.
ETNA Products’ newest family of fluids, SynMAX™ Ultimate Coolants fall into this category of products. They are formulated to provide the best in lubricity additives for even the most severe applications. They benefit from breakthrough technology that exceeds emulsifiable and semi-synthetics in machinability on both steel and aluminum.
