Ideal for flying cutoff saws…

BRUNSWICK, OH –Tru-Cut Saw, has developed a new nanocomposite PVD coating that dramatically increases blade life in circular ferrous and non-ferrous sawing applications.

The new coating, called ViTA-Nano, was developed by Tru-Cut’s ICO Surface Coatings Division. The coating is a proprietary combination of titanium, aluminum, aluminum-titanium, chrome and silicon. Unlike multi-layer coatings in which each material is deposited consecutively, with ViTA-Nano, all cathodes in the PVD chamber are turned on at once – resulting in a more cohesive, harder coating. Saw blades coated with this material will run a minimum of 30 - 50% faster with less scrap and increased production rates compared to AlTiN coatings.

Richard Otter, VP Sales for Tru-Cut Saw & ICO Surface Coatings said, “ViTA-Nano blades are ideal for flying saw machines, re-cut machines and high production sawing machines. Users will see immediate cost benefits in longer blade life when sawing with the ViTA-Nano coating.”

Oil country tube sawing comparison

At one of Tru-Cut’s customer plants, a cutting test compared an AlTiN saw blade with the ViTA-Nano coated blade:

Material: 24” x 24” x 0.286” thick, X-70 Oil Country Tubular Goods Steel
Yield Strength: 70 ksi
Tensile Strength: 82 ksi
Test Results:

AlTiN: 180 cuts (3,879 sq. in.) before tooth failure

ViTA-Nano (3-blades tested)
232 cuts (4,999) 30% increase
246 cuts (5301 sq. in.) 37% increase
264 cuts (5,689 sq. in.) 47% increase

ViTA-Nano blades are much better than AlTiN for sawing hardened steels, cast iron, aluminum and super alloys. The blades withstand 33% greater temperatures and last longer because blade edges are protected from steel build-up (which reduces tool life) for a longer period of time. Tru-Cut recommends dry cutting with VITA-Nano blades to further reduce coolant costs.
