要約
(EN)

A corrosion preventing apparatus including: a water purifying part that includes a hydrogen-ion form resin and a hydroxy-ion form resin; an anticorrosive part that includes a cation form resin and an anion form resin having anticorrosive ions supported thereon; a conductivity measuring part that measures a measured value of conductivity of a machining liquid; and a control part that controls a flow of the machining liquid to the water purifying part and the anticorrosive part on the basis of the conductivity measuring part; wherein the control part performs control on the basis of predetermined first and second conductivities and the measured value measured by the conductivity measuring part.
