METHOD OF CUTTING ZONE PROTECTION AGAINST SPREADING OF CUTTING FLUID VAPORS AND SPLASHES BEYOND ITS BOUNDARIES AND DEVICE INTENDED FOR ITS EMBODIMENT Russian patent published in 2000 - IPC

FIELD: mechanical engineering. SUBSTANCE: method and device may be used in machine-tools with vertical arrangement of rotated machining tool axis with use of cutting fluid in process of machining. Simultaneously with cutting fluid supply to cutting zone continuous circular curtain is produced from cutting fluid around tool, thus forming closed zone. To this end, needed quantity of cutting fluid in form of circular jet enveloping the tool is supplied additionally. Suction of cutting fluid vapors from the above-indicated closed zone may also be performed. Device has detachable circular collector secured concentrically on body of machine drilling head. Collector is provided with circular slit on side facing the part being machined, and provision is made for cutting fluid supply to collector cavity. Collector is made sectional with rectangular form of channel in radial section. Flow rate of cutting fluid supplied exceeds that through circular slit of collector to prevent breaking of circular curtain continuity. In process of machining, closed zone produced from cutting fluid around tool blends cutting fluid evaporations in working zone, prevent their spreading into equipment servicing zone and precludes cutting fluid splashing. EFFECT: enhanced efficiency. 7 cl, 2 dwg
