a random orbital finishing apparatus for finishing the surfaces of solid material including wood , plastic , metal and composites , but most particularly plastic solid surface materials . the apparatus includes a conveyor for transporting such unfinished material pass a uniquely mounted random orbital sander where it is subsequently finished thereby . the random orbitals may be dually mounted and in an offset position . the apparatus may further include a system of proximity sensors and air cylinders which enable the random orbitals to automatically adjust their position onto the surface to be finished when the material is passed thereby and subsequently return back to a starting position after the material passes .
