ABRASIVE FLEECE POLISHING DISCS - INSTRUCTIONS FOR USE

PRODUCT DESCRIPTION ABRASIVE FLEECE POLISHING DISCS

EICKELIT abrasive fleece flap wheels consist of a large number of flaps of a nylon fleece with firmly bonded abrasive grain. They are suitable for cleaning, fine grinding, satin finishing and matting of non-ferrous metals and steels as well as a variety of other applications.
EICKELIT corrugated abrasive fleece polishing wheels are suitable for large-area cleaning or matting of non-ferrous metals and stainless steels. The corrugated shape of the fill ensures a strong cooling air flow and thus the highest efficiency and long service life of the abrasive fleece shaft polishing wheel. The flexible fill allows uniform processing of shaped surfaces

Material description Abrasive Fleece

In the production of abrasive fleece, abrasive particles such as silicon carbide ("carborundum") or aluminium oxide ("corundum") are firmly bonded to a nylon fibre tangled fleece with the aid of synthetic resins. Consequently, the strength and cooling effect of the abrasive fleece depends largely on the fibre thickness, the fleece density as well as the physico-chemical properties of the binders used
Due to its open structure, the fibre abrasive fleece is self-cleaning and therefore does not clog during sanding. Furthermore, the chemical and physical resistance of the synthetic fibre composite allows not only dry use but also wet use together with aqueous or oily media
Due to the flexibility of the tangled nonwoven, even complex profiles and geometries can be processed very efficiently with gentle abrasion. Due to the constant wear of the backing material, fresh abrasive particles are always released at the tool surface in uniform concentrations. This is why polishing tools made of fibre abrasive fleece are particularly low-maintenance and thus provide a very uniform grinding pattern throughout their entire service life

Material description ALUMINIUM OXIDE (AO) / "CORUNDUM"

Aluminium Oxide ("corundum") consists of 95 % aluminium oxide and is the most commonly used abrasive on bonded abrasives. With increasing purity, however, 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 sanding pattern. Therefore, we mainly use abrasive fleeces with doped and consequently tougher types of corundum. On the one hand, this increases the service life of the polishing tools, and on the other hand, the grinding pattern appears more balanced overall compared to undoped aluminium oxide.

Material description SILICIUMCARBID (SIC) / "CARBORUNDUM"

In contrast to corundum, the Silicon Carbide ("carborundum") used in abrasive fleece consists of very sharp-edged crystals. This is the best choice when the fundamentally harder and more brittle properties of SiC are required. This is because SiC abrasive grains consist of only a few crystallites with a precisely adjusted size distribution. As a result, SiC-based abrasive fleeces are sharper compared to aluminium oxide and deliver more effective stock removal. Due to their hardness, the industry uses SiC-based abrasive fleeces especially on non-ferrous metals, stainless tool steels as well as ceramic and mineral materials.

Applications

Abrasive fleece polishing wheels are suitable for surface treatment of metals (steel, INOX, NE and NE alloys) and non-metals (plastics, lacquers, wood, etc.)
Their wide range of applications includes e.g. cleaning, descaling, deburring, fine grinding, roughening, matting, satin finishing, etc.

Instructions for Use

New non-woven abrasive polishing discs must first be carefully run in until a uniform grinding pattern is achieved
In order to avoid overheating and the resulting disturbance of the surface structure, which is difficult to remedy subsequently, non-woven abrasive polishing tools should be operated at moderate to low pressure as far as possible
As a general rule, a lower cutting speed produces a coarser matt finish
The following guide values apply for the typical cutting speeds of non-woven abrasive polishing tools:

Non-ferrous metals 15-25 m/s
Steels 15-25 m/s
Thermosets 10-25 m/s
Thermoplastics 8-15 m/s
Acrylic Glass 3-8 m/s
