PROEXPORT PROJECT · ROLLER RECONDITIONING

Winder roller reconditioning — Reifenhäuser

Chrome plating and polishing of the working surface

We turned the damaged roller surface down to a diameter below the depth of the damage. We then carried out grinding, chrome plating, regrinding and polishing. After completing the work, we measured the surface roughness.

COMPONENT CONDITION BEFORE REPAIR

Scope of winder roller reconditioning

The repair covered the damaged working surface of the roller. Its condition required removing material down to a diameter below the depth of the damage, followed by surface preparation for chrome plating and finishing.

The scope of work was determined by the condition of this particular component. The journals and bearing seats were in good condition and did not require repair.

FIVE MACHINING AND FINISHING STAGES

Turning, grinding and chrome plating

We reconditioned the roller in five consecutive stages, from removing the damaged layer of material to polishing and surface roughness measurement.

  1. Turning

    We removed material down to a diameter below the depth of the surface damage.

  2. Grinding before chrome plating

    We ground the roller surface before applying the coating.

  3. Chrome plating

    We applied a chrome coating to the prepared roller surface.

  4. Grinding after chrome plating

    We machined the applied coating.

  5. Polishing

    We finished the surface and then measured its roughness.

BEFORE AND AFTER RECONDITIONING

Surface requiring reconditioning

The surface damage required turning the roller down to a diameter below the depth of the damage and preparing it for further machining.

Surface after chrome plating and polishing

After finishing, the chrome coating was 100 µm thick. The measured surface roughness was Ra 0.06–0.18 µm.

PROJECT RESULTS

Final parameters after finishing

ParameterProject result
Final chrome coating thickness100 µm
Surface roughness measured after polishingRa 0.06–0.18 µm
Journals and bearing seatsGood condition; no repair required

The 100 µm thickness refers to the finished coating after grinding and polishing. The stated Ra range is based on measurements taken after polishing this particular roller.

TECHNICAL ENQUIRY

Enquire about roller reconditioning

Send photos of the damage, the basic roller dimensions and a description of how it operates in the machine. Include details of the existing coating and the required surface parameters, if available.
