At processing of a metal process, much problems are happening by mixing between slide-way fluid and water-solubility metal-working fluid(MWF). In this study, measure physical & chemical properties and biodegradable properties of base stock and additives that is used to lubricant, and developed water-soluble metal working fluid by slide-way fluid combined use. Biodegradability of developed combined use fluid for 28 days is displayed lower than 10 ppm, and more superior performance than similar fluids in lubrication special quality test.

A proposed testing method of lubricating oil and lubrication characteristics and lubrication quality for gasoline engine, when the engine oil is used for longtime of period. The result shows that the characteristics of engine oil were changed at 30,000km driving distance to the viscosity of 7.82, viscosity index 3, lubrication 40um and at 75,000km driving distance the viscosity of 76.01, viscosity index 10, lubrication of 88. The lubrication characteristics and quality of lubrication and performance of lubricating oil was changed rapidly for the driving of distance. The result dose not consider the properties of fuel used.

Recently, the enterprises solve like this problem, for a cost saving the amount used minimization of the water soluble cutting oil they research. The results are applied from the enterprise. The method which minimizes the use of the water soluble cutting oil is dry processing, MQL(Minimum Quantity Lubrication) and compressed cold air use method. And, according to quality of material of the work the tool wear and surface roughness changes. Researched processing quality from this dissertation. Uses TiN coated hardmetal tool and experimented the quality of material which is various in 4 methods(Dry, MQL, -30℃ Cold air, coolant). Experimented and got the next result. The material where the cut heat is high when metalworking-oil or cold air applying, was visible the tendency where the tool wear quantity comes to be few. And, MQL of the lubricating efficiency which is excellent or coolant compared in different cooling system and was visible the tendency where the surface roughness result gets better.
