Frequently asked questions
What is this abrasive roll used for?
It is used with belt sanders and calibrating machines for sanding, polishing, or finishing operations on the material indicated in the model.
The choice of model depends on width (75 mm), length (50 m), grit (60-220), and the type of application (coarse grinding, intermediate sanding, or finishing).
Which grit should I choose?
K36-K60 for aggressive roughing and paint removal, K80-K120 for intermediate sanding, K150-K240 for pre-painting finishing, 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).
Which materials is it compatible with?
The model indicates the specific material: stainless steel, aluminum, wood, plastic. Use the correct consumable to optimize durability and processing quality.
For stainless steel, use grinding wheels/abrasives with appropriate binders to prevent heating and deformation. For aluminum, prefer abrasives with reduced loading.
How many pieces does the package contain?
The number of pieces is indicated in the model (e.g., "4 pieces", "5 pieces", "6 pieces"). Multiple packages allow for managing replacement pauses without machine downtime.
For intensive use, it is advisable to keep at least 2-3 packages of the most commonly used grits in stock, so as not to interrupt production when a belt/sleeve runs out.
How should abrasives be stored?
Store in a dry place, away from humidity that 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-backed abrasive belts. Recommended temperatures: 18-25 °C, relative humidity 40-60%. Closed and ventilated warehouse.
