Abstract: A device (21) for controlling a spindle of a grinding machine (1) is disclosed. The spindle includes a rotor (5) supported by two radial magnetic bearings, one axial bearing, and a grinding wheel (6). The device includes a storage means (22) for storing control coefficients of the magnetic bearings. The device includes a means for determining a type of the grinding wheel and a type of the rolling bearing ring. A selection means (23) selects control coefficients associated with the determined types of grinding wheel and of rolling bearing ring from among the control coefficients stored in the storage means. The device also includes a means (23) for controlling the radial and axial magnetic bearings. Said means controlling the radial and axial (12) magnetic bearings on the basis of the control coefficients of the determined types of grinding wheel and of rolling bearing ring.
