Abstract
A grinding/polishing machine includes first and second grinding units. The first grinding unit is mounted slidably on a column on a base support to move along a Z-axis direction, and has a first grinding wheel. The second grinding unit is mounted slidably on the first grinding unit to move along a Y-axis direction and has a second grinding wheel aligned with the first grinding wheel. When the second grinding wheel is in a grinding position, the second grinding wheel is situated between the first grinding wheel and a platform mounted on the base support to hold a workpiece. When the second grinding wheel moves away from the first grinding wheel, the first grinding wheel is movable to the platform for a grinding operation. The first and second grinding wheels have different levels of coarseness/fineness.
