The Hidden Carbon Cost of Coolant: Rethinking CNC Milling for True Eco-Friendly Product Design
Most “green” CNC milling strategies focus on material waste, but the real environmental culprit is often the coolant system. Drawing on a decade of firsthand projects, this article reveals how switching to near-dry machining (NDM) and optimizing toolpaths for dry cutting can slash a product’s carbon footprint by over 40% without sacrificing precision, backed by a detailed case study of a consumer electronics enclosure redesign.
