All global distributors want to buy good-quality abrasive non-woven wheels, also called abrasive polishing wheels, to use with angle grinders to get a better finishing effect.
1. Non-woven wheel weight and density:
When a client requires a non-woven wheel, they will ask for a price based on the non-woven wheel's diameter, thickness, and weight. Yes, most buyers judge non-woven wheel weight. Weight is one of the important factors, not the only one. We have to check each raw material (abrasive grain, phenolic resins) percentage, because each factory's production formula, process and density standard will has some differences.
2.Polishing Rate
To check abrasive non-woven wheels quality, Do not trust too much on the product parameter, the best way is you test the quality by yourself.To check the Material Removal Rate and the polishing effect. Good polishing will be like this; uniform surface, no burn; no deep scratch;
NOTE: TEST should be under same condition: same machine, same work-piece, same workers, same pressure and same angles.
3. Polishing Consistent
Good abrasive polishing wheels from the first seconds to the last will keep same stable polishing effect. No heat, no layers dropping.
4. Right usage for abrasive non-woven wheels with angle grinder.
Distributors need to know some knowledge about right usage of abrasive polishing wheels so that they will know if it is real quality problem when end users complain;
The right speed for angle grinder: for most of the surface processes, low and middle speed can get good result. Basically, we need to adjust speed based on working material and working target. Normally more speed has much more material removal capacity, which more suitable for rust removal; and if less speed, then less heat and more suitable for fine polishing;
5. Choose right abrasive grain grit number from coarse to fine.
6. Use soft pressure to get a stable polishing effect. See YANDISC polishing case here;
For abrasive non-woven wheel, best result is to finish the whole process by the material structure not by overpressure.
To buy good-quality abrasive polishing wheels is not about choosing a product but a reliable manufacture/supplier; Good and trusted suppliers as Yandisc will has stable quality of each shipment; supporting clients to grow up together like Yandisc's own business; and good after-sales service.
