Abstract

The invention discloses a near-dry lubricating oil used for cutting. The lubricating oil is friendly to environment, and is neutral; low smog, no stink and no irritation to eyes or skins are realized in the processing process; the lubricating oil difficultly generates foams and mists in the high pressure flowing process, always keep good fluidity, and has protruding cooling performance; the volatilization loss is small, the service life is about 5 years, and loss supplementation can be only carried out without replacing the lubricating oil; the lubricating oil has protruding wear resistance, and can substitute or can be dissolved in most domestic and imported cooling oils; the lubricating oil has good boundary lubricity, excellent high temperature resistance, good extreme pressure resistance, and obvious low smog; the lubricating oil has a short-time antirust performance, and realizes no cleaning after processing, application of antirust oil is avoided, and the obtained cut product is convenient to use and maintain; and the lubricating oil has good high temperature resistance and certain extreme pressure.

Description

technical field [0001] The invention relates to a lubricating oil, in particular to a quasi-dry lubricating oil for cutting and a preparation method thereof. Background technique [0002] Quasi-dry lubricating oil is a lubricating coolant used in high-speed machine tools for micro-quantity and quasi-dry cutting. Dry compressed air enters the cylinder, atomizes the cutting oil in the cylinder, and sprays it on the cutting tool at high pressure to realize environmental protection and low-consumption micro-quantity lubrication. Traditional quasi-dry lubricating oil is prone to produce smoke and odor during processing, which pollutes the working environment and damages human health. In addition, the traditional quasi-dry lubricating oil has high volatilization loss and short service life. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a quasi-dry lubricating oil for high-speed cutting with low volatilization loss,...
