Spinning machine

Nihon Spindle SR200-T4

Rollers rotating along the tube's perimeter spin the blank tube. This innovative spinning process significantly reduces the need for traditional press and welding methods, resulting in substantial decreases in both welding requirements and production costs.

Main Characteristics

  • Die-Free Operation: Allows spinning of the tube with a brick inside, eliminating the need for dies.
  • Stable Clamping: The tube clamp section remains free from centrifugal force, as the tube does not rotate.
  • Continuous Operation: No need to stop the spindle for tube loading, reducing cycle times.
  • Customizable: Offers a wide range of options to meet diverse customer requirements.
