The expander rollers FAPI-VU-HAND are an optimal grinding tool for working with all types of abrasive sleeves.
The expander rollers are exclusively equipped with a specially grooved coating of foamed Vulkollan®, whereby the abrasive sleeve is clamped by the centrifugal force during the machining process. The expander rolls coated with foamed Vulkollan® (VU) are often referred to in practice as “expander rolls with foam” or “abrasive sleeve carriers”.
Advantages
Advantages of the FAPI-VU-HAND expander rollers with a coating of foamed Vulkollan®:
- Wear resistant
- oil resistant
- greaseproof
Due to these outstanding properties, the FAPI-VU-HAND expander rollers have proven themselves on the market for years.
Coating hardness
Only one level can be selected for the hardness of the foamed Vulkollan® coating. The spectrum here lies in the area of the soft covering made of foamed Vulkollan® with 45º Shore (A). A softer or harder design of the coating would cause the individual “flaps” of the expander roller FAPI-VU-HAND to expand too much or too little during the machining process due to the centrifugal force in order to clamp the abrasive sleeve correctly. However, we also manufacture expander rolls FAPI-VU-HAND in other hardnesses at the express request of the customer.
