Spinning machine
Nihon Spindle SR150-T4

Blank tube shall be spun by rollers rotating along the tube perimeter. Compared with the conventional process (press and welding), this spinning process enables big reduction of welding process and the production cost.
Main Characteristics
- Die-Free Spinning: Enables spinning of the tube with a brick inside, as no internal dies are required.
- No Centrifugal Force: The tube clamp section remains free from centrifugal forces since the tube does not rotate.
- Non-Stop Operation: Eliminates the need to stop the spindle when loading a tube, reducing cycle times compared to the work rotation method.
- Customizable Options: A broad selection of configurations available to accommodate diverse customer needs.
