Hot Straightener

Reika straightening machines in rigid construction for permanent precise tube straightness. The Reika machine design assures long life and low operating cost.

Straightening Lines

Example: Straightening Machine RRM 103


  1. Hot-rolled, drawn, cold-pilgered and longitudinally welded tubes
  2. Hot-rolled and drawn round bars
  3. Low and high alloy carbon steel, stainless steel, Inconel
  4. Tempered steel
  5. Non-ferrous metal

_ Benefits:

  1. State-of-the-art straightening technology in machine tool design
  2. Single drives with process monitoring control (i.e. torque and speed)
  3. Narrow roller distance
  4. Low roller wear due to individual arrangement
  5. Automatic and repeatable precision of roller setting:
    1. No-wear column clamping
    2. Absolute encoder
    3. Single arrangement (19/11 axis)
    4. Integrated database
    5. Interpolation mode
  6. Material saving and sound-absorbing transport systems
  7. Automatic tube inlet and outlet systems available
  8. Slant bed design available
  9. Easy to integrate extraction and emulsion units
