PURPOSE: A cutting oil supplying device is provided to stably supply cutting oil to a cutting machine system and to prevent the foreign material from sticking on the inside of a cutting oil supply valve. CONSTITUTION: A cutting oil supplying device comprises a cutting oil supply valve(100), an air feed member(200) and a flux detection switch(300). A vertical space part is vertically penetrated through the inside of a cutting oil supply valve. The cutting oil supply valve has a body and a piston. First and second hydraulic holes are formed on the side part of the body and have an inlet and outlet, which are passed through a vertical space part. The air feed member supplies the compressed air to the first air inlet hole and the second air inlet hole by turn. The air feed member supplies the compressed air to the second air inlet hole to elevate the piston.
