EICKELIT Si-W-PK pre-polishing discs consist of 12 layers of pressed sisal fabric firmly quilted with linen yarns. Due to the special strength of the Si-W-PK sisal fabric discs, they are particularly suitable for pre-polishing metal surfaces and especially for hard materials such as stainless steel. Pre-polishing with SI-W-PK provides a silky-matt surface that can be further processed in the subsequent polishing steps to a flawless high gloss.
12 plies of highly compressed sisal fabric for high counter pressure and effective pre-polishing after sanding
Circular quilted circles made of natural linen machine thread at a distance of 10 mm. These yarns dissolve during the polishing process without leaving any residue
Each Si-W-PK pre-polishing wheel is individually calibrated for low-vibration concentricity. This ensures a high level of work safety and a particularly uniform polishing pattern
Diameter 400 mm, thickness approx. 27 mm
Vmax = 40 m/s, Umax = 1,900 min-1
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.
Sisal fibers are produced globally as a renewable raw material from various agave species. Similar to many other natural fibers based on cellulose, sisal fibers are also very resistant to physical and chemical stress. Sisal is also characterized by its particular toughness and tensile strength, while at the same time the sisal fiber has a high degree of rigidity. Thanks to these properties, polishing tools made of sisal fabric are particularly suitable for the extreme mechanical loads when pre-polishing metals.
Areas of application
Non-ferrous metals, tool steel, stainless steel
Fine grinding, pre-polishing, satin finishing, matting
Pre-polishing with sisal fabric pre-polishing discs produces surfaces with a silky sheen to a matt finish
Pure sisal is abrasive, its effect is comparable to fine sanding with a grit of approx. 280
Polishing discs with diameters > 200 mm should only be used on the fixed polishing stand
During the long period of use, polishing tools should be regularly redressed. This applies above all as soon as polishing pastes have solidified or the polishing discs are heavily soiled with material abrasion.
