Si-W-PK pre-polishing discs are made of 12 firmly bonded layers of sisal fabric biased 45° against the weaving direction. Due to the very firm quilting of the plies, Si/W/PLK sisal fabric discs are suitable for pre-polishing all metal surfaces and especially for stainless steel. Pre-polishing with SI-W-PK produces a silky-matt surface, which can then be optimally processed in the subsequent finishing processes.
12 layers of compacted sisal fabric with maximum counter pressure for intensive pre-polishing
10 mm quilted circles with natural linen machine thread that wear off without leaving any residue when polished at the same time as the sisal
Individually calibrated for low-vibration operation, ensures safe work and a trouble-free polishing finish
Diameter 150 mm, thickness approx. 27 mm
Vmax = 40 m/s, Umax = 5,100 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.
Sisal is a natural fiber raw material that is produced from special agave species in tropical and subtropical cultivation areas. Like other natural fibers, sisal fibers are highly resistant to physical and chemical influences. As a fiber, sisal is extremely tough, tensile and comparatively stiff. That's why polishing tools made of sisal raw material are particularly suitable for the high demands that are typical when pre-polishing metals and especially steel.
Areas of application
Fine grinding / pre-polishing of all metals: aluminium, brass, iron, stainless steel
Sisal fabric has slightly abrasive properties corresponding to approx. grit 280-320. Depending on the pre-polishing paste used the result is matt to satin-matt surfaces
Due to their perfect concentricity, polishing discs with a diameter of up to 200 mm are particularly suitable for manual use with straight grinders, angle grinders or flexible shafts. Larger diameters should only be used on the polishing stand
For pre-polishing with SI-W-PK, we recommend the use of special solid pastes for pre-polishing, grain sizes of approx. grit 240 (non-ferrous metals) and approx. grit 280 (steel / stainless steel)
Please select the type of cutting disc that best suits your polishing project from the above table (5 = "more" → 1 = "less")
Dressing of sisal polishing tools
Prerequisite for an optimal polishing result is the careful preparation of your polishing tool. Therefore, please follow the recommendations for preparing sisal polishing tools
Used sisal polishing discs should also be cleaned and dressed regularly. This applies above all if residues of polishing paste have solidified or the pre-polishing discs are heavily contaminated with material abrasion.
