PURPOSE:To improve workability by a device and reduce its noise, by arranging a plurality of feed tubes to be lined in a circular shape while recirculating lubricating oil in a hollow part for a bar material fed by a push rod. CONSTITUTION:A supply device, arranging eight feed tubes 5 to be lined in a circular shape at a predetermined space and controlled by a rotary angle detector 14, stops the feed tube pitch by pitch. The device, inserting a push rod 15 into a hollow part 9 in the tube 5, supplies a bar material 4 to a main spindle of a lathe. The device improves workability because the bar material 4 is supplied by successively rotating the plural feed tubes 5. The device, supplying lubricating oil to the hollow part 9 of the tube 5 via a supply oil pipe 23 to be recirculated via a pipe 27, reduces a noise due to a contact between the bar material and the tube. |
