Abstract: A grinding machine provided with a spindle (5) rotating under the influence of a cantilever mounted rare earth permanent magnet motor (40). Hydrostatic fluid film bearings (41, 42) are provided between the ends of the spindle (5) and a bronze bearing (64, 65) to support spindle (5) in such a manner so as to eliminate wear. A single oil reservoir (20) is used to supply oil to the hydrostatic bearings (41, 42), as well as to the cooling jacket labyrinth (17) of the motor (40).
