Abstract
In this paper two new small and lightweight spindles for the implementation in desktop sized machine tools are introduced. In both spindles, the tool shaft with a micro tool on the tip (e.g. micro end mill, micro pencil grinding tool or Electrical Discharge Machining (EDM) electrode) works directly as a rotor and is supported by aerostatic bearings. The spindles are driven via air turbines and reaches high rotational speeds in combination with high rotational accuracies. One spindle was implemented in a desktop-sized machine tool and used for micro machining of titanium and brass. With the high rotational speed of the spindles very high material removal rates can be achieved. Thus, the productivity of the micro machining process is enhanced.
