Tool Coating

Several types of cutting tools can be protected with coatings harder than regular A1TiN coatings by combining A1TiN grains with an amorphous silicon-nitride matrix.

PVD titanium-diboride coating machines aluminum without built-up edge.

Thin-film coatings evolve to improve cutting performance and accommodate new tool and workpiece materials.

Compared to AlTiN and TiAlN, the percentage of aluminum is higher in an aluminum-chromium-nitride PVD tool coating.

Technological developments in manufacturing during the last half century.

There is more to recoating cutting tools than meets the eye.

New equipment allows deposition of hard and tough nanocomposite tool coatings.

Molybdenum disulfide tool coatings improve the machining of aluminum, titanium and nickel-base alloys--even when dry.

Aluminum-titanium-nitride coatings continue to evolve.

A coating system that combines a patented surface impingement process and tungsten disulfide prolongs cutting tool life, but does it promote faster speeds?
