は、水溶性油剤に劣っている。Cutting fluids are generally classified into water-soluble oil agents and water-insoluble oil agents, each having the following characteristics. First, since the water-soluble oil agent has excellent cooling properties, it has the advantages that the processing accuracy can be improved and the tool can be prevented from thermal degradation. Further, since it is used as an aqueous solution, it has the advantage that it is not flammable and there is no risk of fire. However, since it is used as an aqueous solution diluted 10-fold to 50-fold, it has a drawback that the oil film is weak and the lubricity is inferior as compared with a water-insoluble oil agent. On the other hand, the water-insoluble oil agent is superior to the water-soluble oil agent in the effect as a cutting oil such that a good finished surface can be easily obtained and the tool is less worn because it has excellent lubricity. However, it is inferior to water-soluble oils in terms of cooling and fire prevention.

場合や、人的傷害（火傷）を被る場合が発生している。By the way, at the machining site, the rigidity of the machine is increased and the performance of the tool is improved.
With the improved machine controllability, it has become possible to increase the feed rate and increase the depth of cut. Therefore, not only the cutting heat becomes high and the oil temperature easily becomes high, but also the temperature at the cutting point becomes high and the ignition source area exceeding 500 ° C. is widened. Moreover, the higher the impact, the higher the possibility of spark generation, and the higher the risk of fire. In addition, when the processing machine is automatically operated, a damaged tool may remain in the processing part.When the next processing is performed on this processing surface, the tool is forced against it, resulting in excessive heat generation and fire. There was a fear that Therefore, in general, water-soluble oils are often used with an emphasis on disaster prevention, but water-insoluble oils may be used with an emphasis on finish surface roughness and processing stability. As a result, the machine may be damaged and must be discarded, or personal injury (burn) may occur.

Here, it is possible to add an emulsifier to the water-insoluble cutting oil to make it water-containing, but the fact is that the contained water immediately disappears and the flammability is restored. For example, when used on a lathe, what had a water content of 10% in the morning was less than 1% in the evening. Further, when an emulsifier is added to the water-insoluble cutting oil, the lubricity of the water-insoluble cutting oil will be impaired due to the effect of the emulsifier. The present invention has been made in view of these problems, and enables a stable processing by using a water-insoluble oil agent, and a processing method and a cutting oil used at that time in which measures for disaster prevention are also sufficient. The challenge is to provide.

The water-soluble cutting oil and the water-soluble cutting oil are stored and separated based on the difference in specific gravity, and each of them is reused. In the present invention, since optimal cutting and grinding can be performed according to the processing target and processing state, for example, a water-insoluble cutting oil may be used during processing in which lubricity is important. In this case, since the lubricity is excellent, a preferable cutting process can be obtained, but in addition to this effect, effects such as less rusting and no bad odor due to decay occur. In addition, in order to eliminate the risk of fire at all, the method of claim 1 may be used together. On the other hand, water-soluble cutting oil may be used when the cooling property should be emphasized or when the tackiness of the oil after processing is not desirable. In this case, the advantages of the water-soluble cutting oil are utilized, such that there is no danger of fire, the work piece does not become sticky, the machine does not get dirty with oil, and the cooling property is good. As the water-insoluble cutting oil or the water-soluble cutting oil used, those described in paragraph Nos. 0006 and 0007 are preferable.

Alternatively, it is a mixed liquid containing chlorinated paraffin or polysulfide as a main component and mineral oil, and the water-insoluble cutting oil after use is recovered so as to maintain a water content of about 4% to 20%. There is. According to the study by the present inventor,
It has been confirmed that a water content of 4% or more can prevent flammability, and a water content of 20% or less does not impair the properties as a water-insoluble cutting oil. In order to use the water-insoluble cutting oil in a water-containing state, for example, the water-insoluble cutting oil in a separated state after mixing the water-insoluble cutting oil and water may be used. However, in the present invention, since mineral oil or a mixed liquid of chlorinated paraffin or polysulfide and mineral oil is used as the water-insoluble cutting oil, the water content should be 4% or less for good water separation. There is also. Therefore, in such a case, it is sufficient to slowly stir the inside of the storage tank or use a slight amount of a surfactant to maintain the water content of 4% or more. Incidentally, it is also possible to deal with this by pouring water around the processed portion during cutting.

使用時には０．４７％であることからである。As a preferable water-soluble cutting oil, it was confirmed that an aqueous solution of triethanolamine (Sample 2) was excellent. When the dilution ratio was changed and confirmed, similar results were obtained with an aqueous solution of about 0.1 to 2%. Further, from the composition of Samples 6, 7, and 8, triethanolamine of about 20 to 30%, medium chain fatty acid of about 8 to 15%, and water of about 40 to 60% of water-soluble cutting oil as a main component were diluted 30 times. It is confirmed that an aqueous solution is suitable. In addition, it is considered that the same effect is exhibited if triethanolamine is 15% by weight or more, medium chain fatty acid is 5% by weight or more, and water is 35% by weight or more. In addition, surfactants having a lipophilic group with 12 or more carbon atoms (anionic, cation, zwitterionic, nonionic surfactants including soap) can be used at a content of 0.5% or less when used. It is believed that there is. The reason is that (1) Table 3 shows that the emulsion cutting fluid b (Sample 4) has a better separability than the emulsion cutting fluid a (Sample 3).
(2) According to Table 1, sample 4 has a smaller content of nonionic surfactant A and higher fatty acid than sample 3, (3)
In Sample 4, the total content of sodium petroleum sulfonate, nonionic surfactant A and higher fatty acid was 14%,
This is because it is 0.47% when used.
