Various means are being considered. For example, if an oil agent is used in a closed processing environment and does not go outside including waste oil, the environmental load is reduced. From this point of view, developing a reusable oil agent that does not waste oil is one approach. In addition, a method of developing an environmentally friendly oil agent that has no environmental problem at the time of waste oil can be considered.

る。In particular, during heavy cutting, a large amount of smoke is generated by spraying only oil mist, but no smoke is generated in the method of the present invention using a mixed mist of water and oil. Also, with conventional oil mist spraying, if the piping is slightly longer, relatively large mist (oil particles) adheres to the piping, and stable blowing cannot be performed. Therefore, a large amount of air (120 liters / min or more) is used so that oil droplets become fine particles.
As a result, the fine oil mist hardly adheres to the piping, but hardly adheres to the workpiece or the blade.
The use efficiency of the water oil mist is reduced. On the other hand, in the present invention, by adding water mist to the oil mist, even relatively large particles do not adhere to the pipe, but easily adhere to the workpiece or the blade, so that the use efficiency of the water oil mist is improved.
