DEVICE FOR COOLING THE CUTTING ZONE OF THE METAL-CUTTING MACHINE TOOL Russian patent published in 1995 - IPC

FIELD: machining. SUBSTANCE: device has vortex tube 1 connected with the source of compressed air with branch pipes 3 and 4 for the cold and hot flow, correspondingly, and an ionizer with electrodes connected up to the power supply, that is ring-shaped positive electrode 6 and needle-shaped negative one 7 whose point is directed along branch pipe 3 of the cold flow. In this case the device is equipped with ejector 9 mounted on the output of branch pipe 3 of the cold flow for displacement relative to it and connected with the source of the liquid medium. One of the variants of the ejector implementation is in the form of hollow screw 12 and nut 13 mounted on it for turning and fixed from the axial displacement. EFFECT: enhanced efficiency. 1 cl, 2 dwg
