During recent years high pressure lubricoolant supply in cutting technologies has been emerging, especially for difficult to cut materials in the aerospace industry, for example Inconel 718 or titanium alloys. The potentials are highly promising with respect to reduced flank wear, lowered process temperatures and thus higher achievable productivity rates. This paper aims to highlight possibilities of the technology whilst focusing on energy efficiency matters. The area of conflict between high pressure, thus high power electrical power demand as well as higher productivity rates, and low pressure, thus high energy efficiency, will be discussed in detail and propositions will be made. It will be shown that processes exists in which high pressure lubricoolant supply is highly productive and even ecologically beneficial, despite of the additional power consumption caused by high pressure pumping aggregates.
