2013 R&D 100 Winner
TuffTekMore than 100 million gallons of cutting fluid is used each year in the U.S. to protect wet machining tools. Dry machining is a more ecologically friendly alternative to wet machining, but a lack of available cutting tools that offer the necessary lubrication and desired hot hardness has limited its usage.

NanoMech Inc. has now introduced a technology that offers a potential 500% efficiency improvement on the industry-standard multi-layer coatings for dry machining. Their product, TuffTek, developed with the help of the U.S. Environmental Protection Agency (EPA), the National Science Foundation and the Univ. of Arkansas, features a surface architecture capable of sustaining its own lubrication. Designed to mimic a lotus leaf, the coating features a textured surface that prevents water droplets from spreading, yet provides a nanoscale reservoir for a lubricant. Another biomimetic feature, self-sharpening edges inspired by sea urchin teeth, is made possible by the application of a layer of cubic boron nitride.
