Spinning technology is a cost effective way to form the ends and middle of a tube. Standalone or Fully Automatic cells are available for Concentric, Eccentric and Oblique spin-forming processes.
The Grotnes spinforming has focused primarily on tube forming. Our method eliminates the need for welded end cone transitions and associated assembly costs for manufacturing tube assemblies. Savings from reduced inventory, reduced assembly of component parts, reduced tooling, reduced welding equipment and welding consumables can be realized.
Concentric Spinning
Our concentric spinforming machines form a reduced end profile that is concentrically aligned with the tube's center axis. Some of this equipment features our patented "Dynamic Length Control Technology" and some of the most robust equipment in the industry with active tailstocks available.
