Recently, the dry/semi-dry cutting without cutting oil is proposed for ecology. The establishment of high heat removable technology is required in the future cutting. In this study, as a proposal of the high heat removable technology, the boiling heat transfer in mist cooling was investigated experimentally. Furthermore, the estimation of the cooling in the cutting was examined by using the heat conduction model. The required cooling rate was 5×(10)^3W/m^2K to suppress the heating due to the cutting. The cooling rate was achieved by the boiling heat transfer in the mist cooling for 4l/hr in liquid flow rate and 70 Nl/min in air flow rate. The cooling rate in the mist cooling was related to forming liquid film on a heated surface in the present experimental range.
