Abstract
A machine for processing optical work pieces having a work piece spindle for the work piece driving rotationally about a work piece rotation axis. At least one processing unit has a tool that can machine the work piece and an adjusting mechanism causes a relative movement between the work piece spindle and tool to selectively enable loading, unloading and processing of the work piece. The adjusting mechanism has a linear drive unit and a swivel drive unit that are stacked on each other to rotate the swivel drive unit and the work piece spindle about a swivel axis that is perpendicular to the work piece rotation axis, and has the linear drive unit move the work piece spindle along a linear axis that can be perpendicular to one of the swivel axis and the work piece rotation axis and parallel to or aligned with the other axis.
