The non-woven grinding ring, manufactured with a special non-woven grinding material, consists of a regular shaft fold, which guarantees optimum tool life. It is the most aggressive non-woven abrasive ring from the Picard production range with optimum cooling at the same time. Non-woven abrasive rings with shaft folding are mainly used as wide rollers, which are composed of individual non-woven abrasive rings. Due to the precise folding, the individual non-woven slip rings can be lined up without aisle formation. During the machining process, an absolutely gapless and line-free surface is created on the workpiece.
