摘要: Machining apparatus comprises a spindle (3) having a tool (21) at one end, electromagnets (5,6,11,12) for radially and axially supporting the spindle by magnetic force without contact, position detecting means (14,15,16) for detecting radial and axial positions of the spindle (3), control means responsive to outputs from the position detecting means for controlling current supplied to the electromagnets (5,6,11,12), current measuring means for measuring currents flowing in the electromagnets, and machining control means for controlling machining conditions according to the measured currents. By controlling machining so that the currents supplied tend towards preset values, optimum machining conditions may be achieved with improved accuracy and efficiency.
