EICKELIT flap wheels are constructed from a large number of single flaps of a nylon nonwoven with firmly bonded abrasives. They are suitable for cleaning, fine grinding, satin and matt finishing of non-ferrous metals and steels as well as a wide variety of other fields of application. We offer a large standard range of abrasive fleece types based on aluminum oxide or silicon carbide with different strengths and grain sizes to optimize desired results according to our customers' individual specifications.

In the manufacture of abrasive nonwovens, abrasives such as silicon carbide or aluminum oxide are firmly bonded to a nylon nonwoven by synthetic resins. Consequently, the strength and cooling effect of the abrasive fleece depends largely on the fiber strength, the fleece density and the physico-chemical properties of the binders in use
Due to its open structure, abrasive nonwovens are self-cleaning and therefore do not clog during polishing. In addition, the chemical and physical resistance of the synthetic fiber composite also allows wet use together with aqueous or oily media
Due to the flexibility of the nonwoen, even complex profiles and geometries can be efficiently processed, providing gentle material removal
Because of the constant wear and tear of the backing material, fresh abrasives are constantly released in uniform concentrations on the tool's surface. This is why polishing tools made of nonwovens are particularly low-maintenance and thus provide a very uniform finish over their entire service life
The aluminum oxide abrasives in AO-002 correspond to a grain size of approx. Grit 45 and provide a very rough grinding surface pattern
The abrasive fleece AO-002 has a very firm texture
Corundum / Aluminum Oxide (AO)
Corundum consists of> 95% aluminum oxide and is the most frequently used grinding tool on bonded abrasives. However, as the degree of purity increases, the hardness and brittleness of corundum increase, which has a rather negative effect on the longevity of the abrasive grain and thus the uniformity of the grinding pattern. That is why we mainly use abrasive fleeces with doped and consequently more ductile types of corundum. On the one hand, this increases the service life of the polishing tools and, on the other hand, the grinding pattern looks more balanced compared to undoped aluminum oxide.
Areas of Application
Non-woven polishing tools are suitable for the surface treatment of metal (steel, INOX, non-ferrous metals and alloys) and non-metal surfaces (plastics, paints, wood, etc.)
Their wide area of application includes for instance cleaning, descaling, deburring, fine grinding, roughening, matting, satin finishing, etc.
New abrasive fleece polishing tools must first be carefully run in until a uniform finish is achieved
In order to avoid overheating and a subsequent disturbance of the surface structure that is difficult to correct afterwards, abrasive fleece polishing tools should be operated with as moderate to low pressure as possible
Basically, the rule applies that a lower cutting speed produces a coarser matting image
The following guide values apply to the typical cutting speeds of non-woven abrasive polishing tools:
