    Abstract: According to the ultra-precise machining method for machining a revolution surface (240) on a workpiece (204) held in position by means of the rotor of a workpiece-holder spindle (1), which rotor is mounted through active magnetic bearings on a slide (202), the proper servo-control frequencies of the bearings are adjusted to values lower than 80 Hz approximately, and the rotation speed of the rotor to a value of the order from 20 to 75 Hz, the radial and axial positions of the rotor of the spindle (1) are selectively modified with respect to a rated position by applying to control circuits of the magnetic bearings reference voltages which vary as a function of the control signals delivered according to the position of the tool (207), and the displacement of the slide (202) is inhibited when the control signals are lower than predetermined values. Application particularly to the machining of atypic revolution surfaces by replication from a template.

    Abstract: A spindle assembly (10) for force controlled operation in applications such as the chemical mechanical planarization of semiconductor wafers includes an axially and rotatably moveable spindle (14) driven by a force producing device (14). The force producing device (14) is controlled by a position feedback loop (18) in a first mode of operation and a spindle force control feedback loop (22) in a second mode of operation so that the same force producing device (14) controls spindle movement in the first mode of operation and maintains a constant pressure on a workpiece based on the detected applied pressure in the second mode of operation.
