The correct shape and surface of the roll is not just about aesthetics. It is a key technical parameter that affects print quality, glue application accuracy, rewind stability or clamping in the production process. At Dessa-NV LLC, we perform high-precision shaft grinding, including the formation of special profiles (bomb, saddle), which ensures optimal equipment performance.
🌀 Why shafts are ground
Grinding allows you to:
- achieve the desired geometry (straight, bombing, saddle)
- to obtain the specified roughness (Ra) for interaction with the material
- eliminate runout, ovality, taper
- restore the worn surface
🧭 Types of profiles we make
Profile | What is it for |
Straight geometry | Standard shafts, even clamping |
Bombsuration | Centres the material, prevents it from "running off" |
Saddle (hyperbole) | For double film tensioning |
Individual profile | Customised to the customer's requirements, e.g. with depths or grooves |
We take into account not only the shape, but also the length, diameter, hardness of the coating, and type of load.
⚙️ Equipment and precision
- Industrial CNC grinding machines
- Accuracy - up to 0.01 mm in diameter
- Shaft length up to 6000 mm, diameter up to 800 mm
- Grinding rubber, polyurethane, metal
🎯 The importance of roughness
Depending on the process, the Ra parameter is set (0.2-3.2 µm):
- For pressure shafts - Ra is lower, closer to the mirror
- For drive shafts - higher Ra for better grip
- Special microtexture for applying adhesives or paints
🔁 Grinding as part of regeneration
In addition to the new shafts, we:
- grinding after curing
- Restore old shafts with deformed surfaces
- change the profile or adjust it to the new equipment
Why grinding at Dessa-NV is about precision without compromise
- Own equipment + experienced specialists
- Grinding to a high gloss or specified Ra
- Individual approach to each shaft
- Runout and balance control after machining
📩 Does your roll run unevenly? We don't just grind the surface - we smooth out the entire process.
