Metal Surface Descaling And Polishing

The abrasive non-woven pad can be converted into an impeller-type product, often used for surface drawing and cleaning non-woven roller brushes, and is installed on a fixed or mobile small rotary grinder.

The advantage of this construction is that it combines the high-efficiency polishing properties of the scouring pad with the wide application of the rotary sander. Usually, it can be used as the last polishing process;

The speed can be determined according to the actual situation on-site, but it is generally not recommended to exceed 3000rpm (200mm outer diameter), otherwise, it will affect the durability of the scouring pad wheel.

The rotation speed is 2500rpm, and the glossiness of polished rugged aluminum alloy castings can reach more than 60. This process is common in the grinding of aluminum, copper, or precision-cast components. Of course, polishing fluid (wax) can also be added to increase the gloss further.

And even if the abrasive non-woven pad is made into a wheel shape, its softness of itself has not been reduced, and it can be used directly for manual use if necessary.

Compared with vibrating grinding with coated sandpaper, the cutting force is easier to control, and it is more suitable for water grinding with low cutting volume and polishing. Clean and polish in one step. According to the roughness of the surface to be polished, choose scouring pads of different particle sizes. You can also choose a grinder with its own water spray or vacuum, which has a wider scope of application.
