WATER-SOLUBLE CUTTING OIL AND DECAY PREVENTION METHOD FOR WATER-SOLUBLE CUTTING OIL

摘要

PROBLEM TO BE SOLVED: To provide a water-soluble cutting oil being hardly decayed, and a decay prevention method for the water-soluble cutting oil.;SOLUTION: Raw water 3 is passed through the bio-water 1 at an ordinary temperature and at ordinary pressure to obtain fungistatic water 4. The raw water 3 is city water or distilled water. A water-soluble cutting fluid raw liquid 5 and the fungistatic water 4 are mixed at a specific ratio to obtain the water-soluble cutting fluid 6. A weight ratio when the water-soluble cutting fluid raw liquid 5 is mixed with the fungistatic water 4 is, for example, 1:9. The bio-water 1 is an apparatus for producing water hardly decayed over a long period of time i.e., the fungistatic water by arranging a plurality of approximate far-infrared radiation ceramic board comprising ceramics in a cylinder, bringing the raw water into contact with the ceramic board and activating the raw water by the action of the ceramics. The water-soluble cutting fluid hardly decayed over a long period of time can be obtained by using the fungistatic water as water for the base fluid and diluting the water-soluble cutting fluid raw liquid by the fungistatic water.;COPYRIGHT: (C)2008,JPO&INPIT
