Grinding and polishing machine for grinding and/or polishing workpieces to an optical quality

A grinding and polishing machine for grinding or polishing optical workpieces to an optical quality, said machine comprising:

• at least one tool spindle with two ends and at least one workpiece spindle which can be adjusted relative to one another in directions perpendicular to one another;
• said tool spindle being constructed to hold a respective tool on the same axis at both ends of the tool spindle and being mounted in a spindle housing which can be pivoted about a pivot axis arranged at right angles to the tool spindle in order to provide in each case one of the two tools for engagement with the workpiece;
• a drive system which can drive the tool spindle about the pivot axis for the desired tool engagement with the workpiece and rotate the tool spindle about the pivot axis into various defined angle positions with respect to the workpiece spindle;
• and
• wherein at least one functional element for detecting geometry of the workpiece or for handling the workpiece is attached laterally to the outside of the spindle housing.
