Frequently asked questions
What is this polishing wheel set used for?
It is used with bench grinders and flexible wheels for sanding, polishing or finishing operations on the specific material indicated in the model.
The choice of model depends on the wheel diameter, bore and polishing material (stainless steel, aluminum, wood, plastic) and the type of application. Compatible with bench grinders with a wheel bore of Ø 16 or Ø 20 mm accordingly.
Which grit should I choose?
K36-K60 for aggressive roughing, K80-K120 for intermediate sanding, K150-K240 for pre-painting finish, K320+ for mirror-finish surfaces.
The most common mistake is skipping intermediate grits: going from K60 to K240 leaves deep marks that cannot be removed. Always proceed in consecutive steps (e.g., K80 → K120 → K180).
What materials is it compatible with?
The model indicates the specific material (stainless steel, aluminum, wood, plastic). Using the correct abrasive optimizes durability and work quality.
On stainless steel, use abrasives with suitable binder to prevent overheating and deformation. On aluminum, prefer abrasives with reduced loading. For wood, regular corundum is the standard choice.
How many pieces are in the package?
The number of pieces is indicated in the model (e.g., 4 or 5 or 6 pieces). Multiple packages allow for managing replacements without machine downtime.
For intensive use, it is advisable to keep at least 2-3 packs of the most commonly used grits in stock, so as not to interrupt production when a belt/sleeve runs out.
How are abrasives stored?
Store in a dry place, away from humidity, which can alter the binder. Keep them in their original packaging until use to preserve grit and adhesive.
Humidity particularly damages self-adhesive pads and paper-based abrasive belts. Ideal temperatures: 18-25 °C, relative humidity 40-60%. Closed and ventilated storage.
