Cut to Length Machine With Integrated Tension Leveler
On a cut to length machine the flatness of the finished sheet is decided by the leveler in front of the shear. The work rolls are pre adjusted to the incoming strip thickness and straightness, which is what allows one machine to handle a mixed order book.
- Open welded frame in Q235A steel plate
- Hydraulic servo system for roll positioning
- Work rolls pre adjusted to incoming strip condition
- Widely used in stainless strip processing
Key Benefits
Why the leveler section defines the machine.
Shape Corrected Before Cutting
Correcting plate shape before the cut is what stops finished sheets bowing after they leave the line.
Adjustable To Incoming Material
Work rolls are pre adjusted according to incoming thickness and straightness, so the machine copes with variable feed stock.
Rigid Frame For Stable Results
The open frame in Q235A plate, continuously welded, gives good stress distribution and strong rigidity.
Where It Is Used
Products and sectors.
- Stainless steel strip processing
- Automobile body, door and roof component blanks
- Electrical parts manufacturing
- General sheet cutting from coil
Who It Is For
- Service centres cutting coil to sheet
- Automotive component suppliers
- Electrical parts manufacturers
- Plants replacing an ageing cut to length machine
Problems It Solves
- Sheets bowing after cutting
- Variable incoming strip flatness
- Frame flex affecting cut and leveling accuracy
- Machines that cannot handle mixed material grades
Technical Features
Machine construction.
Main Parts And Hydraulic Servo System
The machine is composed of the main mechanical parts plus a hydraulic servo system for positioning.
Frame And Roll Devices
Frame assembly, pressing mechanism, swing mechanism, upper roll device, lower roll device and sensor device make up the main assembly.
Welded Open Frame
The frame is made from Q235A steel plate, continuously welded after plasma cutting, for good stress behaviour and rigidity.
Specifications
Capability depends on configuration. Reference operating data is listed below.
| Frame Material | Q235A steel plate, continuously welded |
|---|---|
| Frame Type | Open structure for stress distribution and rigidity |

| Main Assemblies | Frame, pressing mechanism, swing mechanism, upper and lower roll devices |
| Thickness Reference | From around 0.6 mm up to 2.5 mm depending on configuration |
| Width Reference | Around 1060 mm depending on configuration |
| Material Strength Range | 205 MPa to 1350 MPa class strip |
Materials
- Q235A steel plate for the welded frame
- Alloy steel work and support rolls
- Hydraulic servo components
Manufacturing Process
Specification Study
Material grade, thickness, width and length programme are reviewed.
Frame Fabrication
Plates are plasma cut and continuously welded, then stress relieved and machined.
Roll And Mechanism Assembly
Pressing, swing and roll devices are assembled with their sensors.
Hydraulic Commissioning
The hydraulic servo system is set up and tested with the roll devices.
Quality Control
- Frame machining inspection after welding and stress relief
- Roll geometry and hardness records
- Hydraulic system pressure and response test
- Sensor calibration record
Customization Options
- Thickness, width and length range to your programme
- Leveler roll configuration for your material grades
- Stacking and packing arrangement
- Automation interface
Use Guide
- Pre adjust work rolls to the incoming strip thickness and straightness
- Record settings per material grade for repeatability
- Check hydraulic response as part of planned maintenance
- Inspect roll surfaces when marks appear on stainless
How It Compares
Against simpler cut to length arrangements.
| Cut to length without leveling | Correcting plate shape before cutting is what keeps the finished sheet flat afterwards. |
|---|---|
| Mechanically adjusted levelers | A hydraulic servo system with sensor feedback allows finer and repeatable roll positioning. |
| Lighter frame construction | The continuously welded Q235A open frame gives the rigidity that holds accuracy under cutting load. |
