EICKELIT pre-polishing discs Si-W-PK are made from 12 individual layers of biased sisal fabric, which are connected by concentric stitching and are aligned at 45° against the weaving direction. As a result, these discs have a high level of strength in addition to their gentle abrasiveness. Sisal fabric discs are therefore ideal for pre-polishing all metals and are used in particular for pre-polishing stainless steel surfaces. Pre-polishing with SI-W-PK provides matt surfaces that are well prepared for further finishing steps.
12 plies of very firmly connected sisal fabric provide maximum counter pressure and an extra strong attack
Concentric quilted circles (10 mm apart) made of natural linen machine thread, which wear off during polishing without leaving any residue and at the same time as the sisal trimming
Each disc is individually calibrated for low-vibration concentricity and a particularly homogeneous polishing pattern
Diameter 250 mm, thickness approx. 27 mm
Vmax = 40 m/s, Umax = 3,100 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.
The renewable sisal raw material is produced in global cultivation areas from special agave species. Like many other natural fibers based on cellulose, sisal fibers are also very resistant to physical and chemical stress. In addition, sisal is very tough, tension-stable and yet quite stiff. For this reason, pre-polishing discs with sisal are used in particular for rough surface polishing of steel that is difficult to process.
Areas of application
Pre-polishing and fine sanding of non-ferrous metals and all types of steel
Pre-polishing discs with sisal provide a matte finish. Pure sisal itself has an abrasive effect, polishing with sisal fabric discs corresponds to fine sanding with a grit of approx. 280
Polishing discs with diameters >200 mm are particularly suitable for polishing on a polishing stand
Please select the type of cutting disc that best suits your polishing project from the above table (5 = "more" → 1 = "less")
Dressing sisal polishing tools
In order to achieve an optimal polishing result, careful preparation of the polishing tool is required. Therefore, please follow our recommendations for stripping of sisal polishing tools
Even dirty polishing tools should be redressed regularly. This applies above all if residues of polishing paste have already solidified on the polishing wheel or the polishing tools are heavily contaminated with material abrasion.
