New orbital cut-off saw for Nucor Tubular Marseilles

Nucor Tubular Products Marseilles awarded Danieli Centro Tube a contract for a new orbital cut-off saw for the existing 5K-ERW mill in Marseilles, Illinois, USA.

The new orbital cut-off saw will cut to length welded tubes up to OD 6 5/8 inch (168 mm) and equivalent square and rectangular sections, with wall thicknesses up to 3/8 inch (9.5 mm) at speeds up to 460 fpm (140 m/min).

The high-speed and cut-to-length performances are obtained thanks to a reduced weight of the moving parts and a powerful, ultra-precise traveling system on the cutting head car.

The new orbital cut-off saw replaces the existing friction saw, with the main target to improve the cutting quality, and eliminate the current cutting burrs. The equipment features cutting-to-length optimization to minimize scrap tube lengths, a fully automatic set-up, a reduced number of jaws, and easy maintenance. Moreover, the new cut-off is designed to fit the existing foundations without any major modifications.

The start-up is foreseen by the end of Summer 2025.
