Orbital Tube Finishing Belts

We regularly manufacture belts with a wavey edge. This has the effect of reducing the aggression as you go around a curve. We also use the wave edge belts when wet grinding aluminium, to prevent swarf lines being left on the surface of the metal.

The most common 240 grit finish is achieve with a medium scotchbrite / surface conditioning belt. If you require a more aggressive belt prior to that then we would normally recommend either a P80 or a P120 belt.

Q-Rail tube is approximately a 320 grit finish so we recommend using the Very Fine surface conditioning belt as your finish point here.

FX87 Ceramic Belts in P36, P40 or P60 grit – For stock removal and serious damage removal.

If you need to remove mill scale then we would recommend the larger Garboli machines such as the LPC500 which uses a belt 1500 x 90mm.  Our most popular belt for this application is our SKU:  FX87/40/1500×90.  This makes particular sense if you are aiming for a final mirror polished finish.  the Ra on a P36 grit abrasive belt is significantly coarser than a P40 grit (almost 25% deeper).

a few years ago Garboli developed the LPC MIRROR range of orbital tube polishing belt sanders.  Because the abrasive belts are easily changed you can pre-polish with the abrasive belts up to a 2000 grit finish then the mirror polishing can be done using the VT/T00 non-abrasive belts with a liquid polish feed.
