Description

Product description Si-W-PK | 300mm

The pre-polishing disc Si-W-PK consists of 12 tightly quilted plies of sisal fabric with a biased weave pattern. The resulting strength of the polishing discs makes them the ideal tool for vigorous pre-polishing of all metal surfaces. Sisal fabric pre-polishing discs are used especially on very hard materials such as e.g. B. stainless steel is used. Surfaces pre-polished with SI-W-PK polishing discs provide a satin-matt shine and are therefore optimally prepared for the subsequent finishing processes.

Product features

Compacted sisal fabric in 12 layers provides maximum counter pressure and extra effective pre-polishing
Circular quilted circles made from a natural linen machine thread spaced 10 mm apart. These wear out without leaving any residue and at the same time as the sisal trimming
Each polishing wheel is individually calibrated for low-vibration concentricity and thus ensures maximum work safety, productivity and trouble-free polishing patterns
Diameter 300 mm, thickness approx. 27 mm
V_max = 40 m/s, U_max = 2,500 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!

Application

The growing areas of the natural raw material sisal are located in tropical and subtropical zones worldwide. The sisal fibers are obtained there from specific agave species. Like many other natural fibers made from cellulose, sisal fibers are also very resistant to physical and chemical influences. Sisal is particularly characterized by its toughness and tensile strength combined with very high rigidity. For this reason, sisal is particularly suitable for rough usage, which are characteristic for the pre-polishing of metals and especially steel.

Areas of application

Fine grinding and pre-polishing of non-ferrous metals, tool steel, stainless steel
The abrasive effect of pure sisal corresponds to a cut of approx. grit 280
Pre-polishing discs Si/W/PK made of sisal fabric provide a matt to satin-matt surface, depending on the polishing paste used
Polishing discs with diameters > 200 mm should only be used on the appropriate polishing block
For sisal pre-polishing discs, we recommend optimal cutting speeds of approx. 25-40 m/s

Dressing sisal polishing tools

The basic prerequisite for optimal polishing is careful preparation of the polishing discs. Therefore, please follow our recommendations and instructions for the optimal dressing of sisal polishing discs
Even dirty polishing tools should be redressed regularly. This applies in particular if residues of polishing paste have solidified or the polishing discs are heavily contaminated due to material abrasion.

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.
