摘要

Device (10) for grinding, fine grinding and / or polishing workpieces (L) of optical quality, in particular of spherical lens surfaces in fine optics, with a machine frame (12), a tool spindle (14), by means of which a tool (WZ) around a Tool axis of rotation (A) can be driven in rotation, and a workpiece spindle (16), by means of which the workpiece (L) can be driven in rotation about a workpiece axis of rotation (C), the tool spindle (14) and the workpiece spindle (16) being perpendicular to one another extending first and second directions (x, z) are axially relatively adjustable (X-axis, Z-axis) and can also be pivoted relative to one another about a pivot axis (B) in a pivot plane (XZ), and a device (18) for cross-grinding adjustment, the one Includes adjustment mechanism (20), by means of which one of the spindles (14, 16) can be positioned in a third direction (y) perpendicular to the first and second directions (x, z) in such a way that the tool rotation axis (A) and the workpiece axis of rotation (C) are in the swivel plane (XZ), characterized in that the tool spindle (14) is axially adjustable in the first and second directions (x, z) (X axis, Z axis ) and can be pivoted about the pivot axis (B) while the device (18) for cross-grinding adjustment engages the workpiece spindle (16) and comprises a clamping mechanism (22) which can be activated independently of the adjusting mechanism (20) and which serves to actuate the adjusting mechanism ( 20) to position the workpiece spindle (16) positioned with respect to the machine frame (12).
