Nanocomposite coating helps increase saw blade service life

Tru-Cut Saw has developed a new nanocomposite PVD coating that helps increase blade life in circular ferrous and nonferrous sawing applications. The ViTA-Nano coating is a proprietary combination of titanium, aluminum, aluminum-titanium, chrome, and silicon.

For deposition, all cathodes in the PVD chamber are turned on at once, resulting in a cohesive, hard coating. According to the manufacturer, saw blades coated with this material run a minimum of 30 to 50 percent faster with less scrap and increased production rates compared to AlTiN coatings.
