DEVICE FOR COOLING CUTTING AREA OF METAL CUTTING MACHINE Russian patent published in 2011 - IPC B23Q11/10 

FIELD: machine building.

SUBSTANCE: device consists of vortex tube connected with source of compressed air and equipped with branch of cold flow, with ioniser installed at output of branch and having circular and needle electrodes connected to power source, further, vortex tube is equipped with ejector connected to source of fluid medium. The device is also equipped with an external nozzle of circular cross section for supply of hot flow. The ejector is installed at the output of the external nozzle in a circular cavity formed with the external nozzle and the branch of cold flow, set off relative to the external nozzle in the direction of a processed item and designed to perform axial travels.

EFFECT: raised efficiency of item treatment due to increased lubricating properties of lubricant-cooling agent flow.
