PROBLEM TO BE SOLVED: To provide a cooling device capable of effectively and economically cooling the vicinity of a cutting edge tip of a cutting tool used in a cutting machine such as a lathe. SOLUTION: This cooling device is provided with an input means, an arithmetic means, a refrigerant supply means 4 for supplying a refrigerant to the vicinity of the cutting edge tip 3a of a cutting tool 2, and a control means. The input means inputs the value necessary for computing the quantity of heat generated around the cutting edge tip 3a of the cutting tool 2. The arithmetic means computes the quantity of heat generated near the cutting edge tip 3a of the cutting tool 2 on the basis of the value inputted by the input means and computes the supply flow rate of the refrigerant necessary for suppressing temperature rise around the cutting edge tip 3a of the cutting tool 2 cause by the computed generated quantity of heat, with the heat of vaporization of the refrigerant supplied to the vicinity of the cutting edge tip 3a by the refrigerant supply means 4. The control means controls the refrigerant supply means 4 to supply the refrigerant at the computed flow rate.
