Precision Straightening Machines – Built for Accuracy: Inside the Manufacturing of Our 150 and 100 Models

Every component precision‑processed – from the roller basement to the main frame – to guarantee straightness <0.3 mm/m for your most demanding metal profiles.
Behind the Scenes: Manufacturing High‑Precision Straighteners
We have just completed the fabrication of our larger‑capacity straightening machines – the 150 model and 100 model. These machines are currently semi‑finished products: the main frames have been fabricated, and the major structural components are in place. The next critical steps are:
Assembling the precision‑ground rollers and drive systems onto the main frame
Precision‑machining the casting parts – particularly the roller basement (the foundation that holds the straightening rolls)
Why This Matters for Your Straightness Results
The straightness a straightening machine can achieve – consistently below 0.3 mm/m – is not a matter of luck. It is a direct result of precision manufacturing at every stage. Every component is manufactured to tight tolerances, but the most critical element is the roller basement:
Roller basement machining – This casting is precision‑machined to ensure that all roll mounting surfaces are perfectly parallel and coplanar. Any deviation in the basement translates directly into straightness errors in the finished product.
Main frame stability – The frame must be stress‑relieved and rigid to prevent deflection under load.
Roll assembly precision – Each roll is mounted with controlled preload and alignment to ensure consistent pressure distribution across the profile.
The Result: A machine that delivers straightness <0.3 mm/m – batch after batch, profile after profile.
What Makes Our Straightening Machines Different – Key Technologies
Feature | Why It Delivers High Precision |
Precision‑machined casting parts | All mounting surfaces are machined to tight tolerances – no deflection, no misalignment |
Stress‑relieved main frame | Prevents frame distortion under high straightening forces |
Contoured rolls | Custom‑machined to match your profile geometry – even pressure distribution |
Closed‑loop laser feedback | Real‑time straightness verification and auto‑adjustment |
Servo‑controlled roll positioning | 0.01 mm repeatability – consistent results every cycle |
150 Model & 100 Model – Key Specifications
Model | Profile Width / Diameter | Typical Applications |
100 Model | Up to 100 mm | Bars, tubes, and profiles for general engineering, automotive, and construction |
150 Model | Up to 150 mm | Large‑section profiles, structural steel, heavy‑duty tubes for oil & gas and shipbuilding |
Both models achieve straightness <0.3 mm/m – with typical performance often reaching <0.15 mm/m.
