Does not change the active wheel spindle dimensions to transform the premise

Without changing the active wheel spindle dimensions under the premise of the transformation.  polycrystalline diamond  shaft design dimensional accuracy and surface roughness of parts in the same circumstances  Synthetic diamond  short journal bearing relax a three-watt, so that does not affect the results at the same time facilitate manufacturing. The pressure oil into the axial thrust surface forces, the two opposite axial  grinding wheel  oil chamber for absorbing force, the axial rigidity of positioning into a liquid friction. Hydrostatic spindle bearing capacity of the oil chamber with hydrostatic bearing four total effective bearing area, oil pressure and oil return chamber gap related.
