Abstract: Proposed is a lubrication system, in particular a single-duct minimum quantity lubrication system, having an aerosol generator, a spindle, a tool clamper arranged on the spindle and a rotary feedthrough arranged on the side of the spindle located opposite the tool clamper, the tool clamper, the spindle and the rotary feedthrough are penetrated by a duct, in the duct is arranged a spindle tube which improves the transport of aerosol, in particular the transport of lubricant particles and/or coolant particles, above all inside the spindle or motor spindle. Further, the spindle tube is mounted in the duct in an electrically insulating manner and/or in that the spindle tube is produced from a material that is not electrically conducting and/or in that the spindle tube and/or the duct is/are provided with at least one electrically insulating layer for coating the spindle tube and/or the duct in an electrically insulating manner.

Abstract: A lubricating system with an aerosol generator, a spindle, a tool clamper arranged on the spindle, and a rotary feedthrough arranged on the side of the spindle lying opposite the tool clamper, a duct runs through the tool clamper, the spindle and the rotary feedthrough. A separate aerosol generator feeds aerosol into an aerosol line to a tool via the rotary feedthrough, spindle and tool holder to transport lubricant particles and/or coolant particles inside the spindle or motor spindle. A spindle tube is arranged in the duct and is mounted non-rotatably on a non-rotating portion of the rotary feedthrough and extends at least through a portion of the spindle in the direction of the tool clamper, and the aerosol generator is connected to the spindle tube, such that aerosol is guided through the spindle tube in the direction of the tool clamper and/or a tool clamped by the tool clamper.
