EP-Polishing Buffs

EP-Polishing Buffs are manufactured from special, wear-resistant cotton materials. “Thread run” of all polishing buffs is always 45° to the buff’s circumference e.g. Minimum material wear.

Outside diameters from 60 to 1000 mm.

The 45° cut to circumference allows for a consistent wear of the buff with very little dust production.

Dressing

EP-Polishing-Buffs can be dressed prior to delivery to save you the initial dust production on initial use. No “working-in” time is necessary for the operator.

Balancing

Care and attention to detail in the manufacture and folding of the polishing buff minimise unbalance. On spindle mounting, buffs should be rotated randomly to eliminate any rest unbalance.

Impregnation

EP-impregnations are environmental friendly, tried, tested and proven. Our L0/10 impregnation can be used on all types of cloth from NKG – C32 to increase the longevity of the buff.

Folding

The type of folding determines the firmness or density of EP-Polishing Buffs.

Rule-of-thumb

– closed, dense folds = firm to hard buff (corrugated wave buff D1WP and D1B) for aggressive pre-polishing

– normal folds = medium to hard, well ventilated standard buffs (type D1A/K)

– open folds = soft, excellent ventilation and the ability to submerge the work piece deep into the polishing roll (type D1C spiral)

Centers

Polishing buffs of all “K” types, i.e. all buffs with steel-clench-ring fitting, are more cost effective than buffs with cardboard centers. Interchangeable, re-usuable steel centers are used plus steel clamping plates to secure buff material on the spindle. The steel-clench-ring does not present any disposal problems.

Solid Cardboard Centers

These can be stapled into all buffs on request for an additional charge. However, these can only be used once.

Keyways, hexagonal and round bores are all possible.
