Frequently Asked Questions
What is this abrasive belt for calibrating machines used for?
It is used with Laguna Supermax series calibrating machines and similar for sanding, polishing or finishing operations on the material indicated in the model.
The choice of model depends on belt dimensions, K grit, and the type of application (roughing, intermediate sanding, or finishing).
Which grit to choose?
K36-K60 for aggressive roughing and paint removal, K80-K120 for intermediate sanding, K150-K240 for pre-painting finishing, K320+ for mirror 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. Use the correct consumable to optimize durability and quality of work.
For stainless steel, use wheels/abrasives with a suitable binder to avoid 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 you to manage replacement breaks without machine downtime.
For intensive use, it is advisable to keep at least 2-3 packages of the most 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 the original packaging until use to preserve grit and adhesive.
Humidity particularly damages self-adhesive pads and paper-based abrasive belts. Recommended temperatures: 18-25 °C, relative humidity 40-60%. Closed and ventilated warehouse.
