ABSTRACT:
In order to reduce the outflow at the front of active liquid bathing the stock in a hydraulic stock-guiding tube of feed apparatus for an automatic lathe, a nozzle part is disposed at the front end of the guide tube in which the piece of bar stock is rotating and advancing. The nozzle includes one or more passages, through which a protective fluid is ejected, opening out into the inside aperture of the nozzle in which the bar is rotating and disposed in an oblique direction pointing toward the rear, i.e., against the flow of active liquid toward the front. This arrangement contributes toward lessening leakage of active liquid and increasing the pressure thereof around the bar, this increase in pressure in turn reducing noise and vibration in the feed apparatus.
