Abstract (en)

[origin: EP0999003A2] The object of the present invention is to provide a bar processing apparatus (2) which simplify the work operation, has a simple structure and is highly effective for preventing the vibration of a bar (W). A bar (W) processing apparatus (2) comprises a collet chuck (8) for chucking a leading end portion of a bar to be machined, a spindle (6) for rotating the bar at a high speed, a hollow tube (10) which is arranged coaxilly with the collet chuck (8) and extends from the vicinity of the collet chuck through the spindle toward an upstream side with respect to a feeding direction of the bar, the hollow tube being provided with a first bar passage (12) whose ends are open and whose inner diameter is of a size which allows to form an oil layer around the outer surface of the bar (W) by the rotation of the bar accommodated within the bar passage, an oil injecting inlet (14) which is open toward the inside of the hollow tube, and oil supply means (16) for supplying oil to the oil injecting inlet (14). <IMAGE>
