A turretless turning machine dedicated to the manufacture of a limited number of parts includes a base, a spindle assembly for holding and turning a workpiece, a motor, a direct drive assembly for transferring power from the motor to the spindle assembly, and a cutting assembly, the base being of sufficient mass and area to provide a damping force that facilitates reducing vibrations and harmonics generated by the machine, the motor and direct drive assembly being adapted to rotate the spindle assembly about a vertical axis at a rate wherein chip fragments aviate off of a workpiece being machined such that heat generated by the tooling process is removed by the chips which have absorbed the heat.
