<p>PROBLEM TO BE SOLVED: To obtain a cutting fluid which improves the adhesion of abrasive grains to a wire saw to permit the uniform cutting of a work by mixing a fine synthetic resin powder having a particle diameter in a specified range with a water-soluble solvent. SOLUTION: The synthetic resin of the fine synthetic resin powder is not particularly limited and may be an arbitrary resin such as a polystyrene, a polyvinyl chloride, an acrylic resin, a polyethylene or a phenolic resin. The particle diameter of the powder is 10mm to 10μm, desirably 0.1-5μm. The water- soluble solvent in which the powder is dispersed is desirably a glycol solvent exemplified by ethylene glycol, propylene glycol, glycerol, 1,3-propanediol or polyethylene glycol. The powder is used desirably in an amount of 0.5-30wt.%. The fluid may further contain 0.2-3wt.% thickener being polyvinylpyrrolidone.</p> |
