Cartridge rolls are suited for applications in specific small inner holes or other hard-to-access places, the smallest dimension of sandpaper rolls is 7mm. Sandpaper rolls are mainly made with coated abrasives and has long tools life. Due to their small diameter, these sandpaper cartridge rolls have to be used on high-speed air tools to achieve an appropriate surface grinding speed.
Grit Size
40#~600#
Raw Material
Aluminium oxide 609; Zirconia
When using sandpaper rolls, Reducing wear and thermal load of the workpiece can be achieved by reducing contact pressure and speed (abrasive paste/oil can be used when appropriate)
In order to avoid unnecessary tool wear and thermal load, choose to switch to coarser-grit abrasive clothes instead of increasing contact pressure to increase cutting force
Increasing the cutting speed achieves a slightly finer surface.
Increasing the contact pressure makes the sandpaper rolls surface slightly more coarse and if you use the same grit size on soft or hard material the surface finish will look coarse on the softer material.
