Development of the Electric Rust Preventive Machining Method

Increased recycled machining water flow quantity (research bulletin)

Abstract

In the machining, machining fluid (cutting oil, grinding fluid) which is contained oil, extreme pressure additive, surface active agent, rust-preventive agent etc. is used. However, because of greenhouse gas outbreak and high cost in effluent treatment (incineration and reclamation etc.), reduction of machining fluid using is demanded. In this investigation, the electric rust preventive machining method system which uses only water (tap water, industrial water, ground water) as machining fluid is developed. In this research bulletin, it is reported that improvement of machining water recycle system is carried out, and over 5L/min purification water which is refined by using reverse osmosis membrane and high pressure pump is achieved.
