An automatic drawing oil supply system that prevents friction heat generated when drawing out the pipe into a thinner pipe by coating drawing oil on a pipe and lubricating the pipe, and reuses the recovered drawing oil by recovering drawing oil remained after it is used into a storage tank through a recover pipe is provided. An automatic drawing oil supply system comprises: a storage tank(11) for storing drawing oil(12); a discharge pipe(14) for supplying the drawing oil stored in the storage tank to the supply pipe by the pump; a pump(15) for pumping the drawing oil received from the discharge pipe to the supply pipe; a supply pipe(16) for supplying the drawing oil received through pumping of the pump into the supporting tank; a supporting tank(17) for storing the drawing oil received from the supply pipe; a drawing oil dropping pipe(18) installed on the bottom of the supporting tank to supply drawing oil into a drawing oil supply pipe installed on an automatic drawing dies centering device(23) by free fall method; and a recovery pipe(19) connected to the automatic drawing dies centering device to send the recovered drawing oil to the storage tank by recovering drawing oil remained after it is dropped onto a pipe from the drawing oil dropping pipe by free fall method to coat the pipe.
