Water-soluble machining fluid for fixed abrasive wire saws

摘要

Provided is an aqueous working fluid for a fixed-abrasive wire saw, the aqueous working fluid comprising (A) at least one water-soluble polymer selected from polyvinylpyrrolidone and a copolymer including vinylpyrrolidone and (B) water, and being able to inhibit: its viscosity increase when mixed with cut debris; reaction between the working fluid and the cut debris and generation of hydrogen; and viscosity increase or gelation of the working fluid mixed with the cut debris.
