Description

Abrasive Non-Woven Flap Wheels

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.

PRODUCT FEATURES

Polishing disc, abrasive nonwoven "very coarse" for rough brushing patterns
Diameter 250 mm / ca. 30 mm Thickness
Hardness 3 = intermediate
Core made of cardboard, reinforced with thermosetting synthetic resin compound
Freely selectable bores 17 - 65 mm
V _max = 30 m / s, r _max = 2,400 min ^-1

Bore Holes

We manufacture your desired bore individually for you. We cover every known bore diameter for industrial polishing machines *
If you need other bore diameters or special adapters (e.g. for hexagonal shafts, with keyways, etc.), we will be happy to manufacture them on request **

* Polishing discs drilled individually at the customer's request are excluded from exchange or return in accordance with our Terms of Cancellation.

** Observe safety regulations for the minimum diameter of drive shafts!

Abrasive Nonwovens

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

Material

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.

Application

Application Instructions

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:
- 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

Safety instructions

Protective Equipment when Polishing

When grinding and polishing, the work equipment used creates considerable health risks. It is therefore compulsory to wear suitable personal protective equipment for work safety when grinding and polishing. In particular, all rotating polishing and brushing tools may only be operated with suitable covers for reasons of occupational safety.

Wear eye / face protection

The fine dust emanating from polishing is harmful to the eyes. Flying parts can cause serious injuries to the face and eyes.

Wear respiratory protection

Fine dust contaminated with heavy metals and respirable, which can only be retained with suitable respiratory protection, is produced during polishing.

Wear protective clothing

Flying parts can cause sensitive injuries all over the body.

Wear gloves

In general, gloves should be worn when grinding and polishing. If there is a risk of being wound up (e.g. drills, processing small parts, etc.), gloves may be prohibited on the basis of a risk assessment.

Wear ear protection

Due to the noise exposure during grinding and polishing, it is necessary to wear suitable hearing protection on a regular basis.
