ABSTRACT:
A grinding and polishing machine, in particular for lenses, has at least one tool spindle and at least one workpiece. The tool spindle is constructed to hold a respective tool on the same axis at both ends and is 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 tool for machining engagement and also at various defined angle positions with respect to the workpiece spindle. A drive arranged on the pivot axis pivotably moves the tool spindle about the pivot axis for the desired machining engagement and rotates the tool about the pivot axis into the various angle positions with respect to the workpiece.
