Abstract
A sanding or polishing or grinding machine includes one or more sanding wheels supported on a machine base and movable up and down relative to the machine base for grinding the work pieces of different heights or thicknesses. A driving device may be used for driving the sanding wheels to move horizontally relative to the machine base for allowing the work pieces to be suitably sanded or ground by the sanding wheels. The sanding wheels are preferably disposed at different angular position relative to the machine base, for suitably sanding or grinding the work pieces in different angular positions.
