Device for lapping and/or polishing free form surfaces of workpieces has circular guide device in which workpiece or tool is mounted so that imaginary centres correspond

摘要

The device has a tension device for the workpiece (2) and a drive device for the tension device. The workpiece or machining tool (3) is mounted in a circular guide device (8) whose imaginary centre (13) corresponds at least approximately with that (12) of the surface of the workpiece being machined. To reach a constant or variable contact pressure between the machining tool and workpiece one of them has a contact pressure device (5).
