摘要

Machine tool, especially for milling, has a workspace (14) with a spindle (10) projecting into the workspace and a suction arrangement for extracting air from the workspace. At least one air supply opening (18) is provided on the circumference of the spindle to connect the surround space (16) to the work space. The spindle has at least one air guiding vane (20) that is driven by the spindle and which sucks air in from the outside and expels it into the workspace.
