Tension Leveller Vibration Investigation
Tension levellers have a major influence on final flatness and surface finish in sheet metal production. Vibration in a leveller can quickly produce chatter marks, waviness, and surface defects that lead to rework and downtime. Vibremo helps producers locate and fix these issues, improving both product quality and equipment reliability.
Tension Leveller Vibration Investigation
In high performance steel and aluminium production, your roll grinding operation must deliver flawless rolls, free from chatter marks and ready for the mill. At Vibremo, we specialise in vibration inspection of roll grinding machines to improve roll surface quality for more time in the mills and maintain production efficiency.

Why tension leveller vibration matters
Tension levellers are crucial for achieving consistent flatness and high surface quality levels in aluminium and steel strip. Vibration can produce chatter marks, waviness, or other surface imperfections.
These problems may come from rotating parts (bridle rolls, gearboxes, drives) or from weak connections and resonant cartridges. Identifying whether chatter is driven by mechanical faults, resonance, or both is essential in order to maintain high quality output strip and avoid unnecessary downtime.
How Vibremo supports you
On-site vibration survey
Measure vibration at cassettes, frames, entry/exit bridle rolls and drives to detect resonances and sources of forced excitation.
Structural assessment
Compare component responses to identify poor connections, loose interfaces or local weaknesses that amplify vibration.
Component defect identification
Use spectral analysis to find gear mesh issues, loose bearings or component imbalances that affect the levelling process.
Targeted recommendations
Deliver clear corrective actions (tightening, support improvements, repairs or part replacement) to remove chatter at source.
Typical findings & solutions
Structural resonance in levelling cartridges is a frequent cause of chatter. Weak or poorly connected cassettes can vibrate independently of the frame, sending vibration through the leveller and marking the strip. By comparing cassette and frame responses, we identify the weak coupling and recommend stiffness improvements or better support systems.
Gear defects in bridle roll drives can generate vibration at gear-mesh frequencies, resulting in fine pitch chatter marks. Spectral analysis allows us to isolate the exact frequency, pinpoint faulty gears or alignment issues, and guide targeted repair or replacement.
Vibration can also travel through the leveller from a single cartridge or drive point, creating overlapping chatter patterns. Comparative testing helps confirm whether the source is local or transmitted, enabling focused maintenance rather than broad rebuilds.
Benefits for your operation

Restore smooth, defect-free strip surfaces.
Improve flatness consistency
Keep product within tighter flatness and thickness tolerances.
Better equipment reliability
Reduce wear on cassettes, bearings and drives through targeted fixes.
Lower downtime & costs
Precise diagnosis prevents repeat interventions and cuts maintenance expense.
