ABSTRACT:
A metal working machine which has a tool support on which a rotatable working spindle is mounted which can be acted upon by oil-free compressed driving air. A separate duct provides oil-free compressed braking air which serves to stop the tool support after compressed air to the spindle has been switched off. Additionally, an oil-free mist is provided to the machine via a duct for lubricating the bearings of the tool support.
