摘要
A spindle apparatus for use at a machine tool, in particular a lathe, has: a spindle assembly including a workpiece spindle to receive an elongated workpiece and a spindle motor for driving spindle rotation; and a rotary guide-bush assembly axially arranged with the workpiece spindle, the rotary guide-bush assembly including a rotary guide-bush to receive the elongated workpiece and supported at the rotary guide-bush assembly to rotate with the elongated workpiece received in the workpiece spindle about the axis while enabling a movement of the elongated workpiece in the axial direction. The spindle and rotary guide-bush assemblies connect to each other by a torque transferring connection, between the spindle and rotary guide-bush assemblies along the axis to transfer driving torque during acceleration or deceleration of the spindle rotation driven by the spindle motor to the rotary guide-bush of the rotary guide-bush assembly.
