Can OSB be sanded?
OSB, or oriented-strand board, is an engineered wood material sold in sheets like plywood. OSB cannot be sanded to take on a particular shape, but a light pass with sandpaper will smooth out the surface so splinters don’t scratch the bottom of the material you install over the OSB.
What is the standard OSB thickness?
Common thicknesses for sheathing panels are: 5/16 inch (7.9 mm), 3/8 inch (9.5 mm), 7/16 inch (11.1 mm), 15/32 inch (11.9 mm), 1/2 inch (12.7 mm), 19/32 inch (15.1 mm), 5/8 inch (15.9 mm), 23/32 inch (18.2 mm), and 3/4 inch (19.0 mm).
How do I get a smooth finish on OSB?

The function of the small rollers is to provide downward pressure on the wood as it is going through the sander. You need to make sure at this point that the bearings move up and down smoothly.
