摘要：
The present invention provides a nonflammable water-based cutting fluid composition which affords excellent dispersion property of abrasives, which does not cause problems involving in flammability upon the use for cutting process of a hard and brittle materials, which can be readily washed, and which can achieve sufficient rust preventive property even if it is used in an equipment for oil use. Provided by the present invention is a nonflammable water-based cutting fluid composition containing a polycarboxylic acid-based polymer compound and/or a salt thereof having a weight-average molecular weight of 1,000 -200,000, and additionally a carboxylic acid and/or a salt thereof upon needs for a rust preventive property.
