Hat trick: reducing friction lets a new coating score in three ways for dry machining. (coatings).

Friction is bad for cutting tools. It causes chips to weld to cutting cutting sides and heat to build up in the two tools and workpieces. These conditions, in move round often lead to high cutting forces that can cause part deflection. However, a fresh cutting tool coating not single promises to overcome these riddles but its goal is to actually increase productivity, reach forth tool life, and deliver of the highest order surface finishes. The coating restores friction so well that it smooth makes rubber slippery.

To display how well the coating performs, an engineer at Sumitomo Electric Carbide Inc., high hill ...
