Abstract
The machine spindle arrangement () according to the invention forms a unit with a motor () as central element. At one side of the motor () a spindle neck () with a spindle () is flanged that is directly driven by the rotor () of the motor (). The spindle () is a so-called null spindle that can be replaced without readjustment with all bearings and other wear parts due to the present exactly adjusted positioning surface () that abuts against an axially properly defined bearing contact surface (). At the backside of the motor () facing away from the spindle (), a tool releasing device () and an angle adjustment transmission () is arranged that serves to rotate a present traverse feed shaft () relative to the spindle (). The traverse feed shaft () serves to actuate an adjustment device at the tool ().
