(1) Classification of cutting fluids: Cutting fluids can be divided into oil-based cutting fluids, semi-synthetic cutting fluids and synthetic cutting fluids.
1, oil-based cutting fluid components: mineral oil 50-80%, fatty acid 0-30%, emulsifier 15-25%, rust inhibitor 0-5%, preservative < 2%, defoamer < 1%.
2. Semi-synthesis: 0-30% of mineral oil, 5-30% of fatty acid, 0-20% of extreme pressure agent, 0-5% of surfactant and 0- 10% of antirust agent.
3. Total synthesis: surfactant 0-5%, 10-40%, amino alcohol 0-40% and rust inhibitor 0-40%.
(2) Characteristics of water-based cutting fluid
1, excellent antirust performance (antirust time is more than three months)
2. The solution is green and transparent with good visibility, which is especially suitable for modern processing equipment such as CNC machine tools.
3. The formula is environmentally friendly and does not contain chlorine, triazine, secondary amine, aromatic hydrocarbon, sodium nitrite, etc. Harmful to human body, non-irritating to skin and friendly to operators.
4. Cutting fluid is not easy to deteriorate and stink, and imported additives are selected, which has strong antibacterial property and long service life in the system or a single oil tank (it will not stink and deteriorate for more than one year).
5, low foam, excellent foam resistance, can be used in high-pressure systems and operating conditions requiring high gas release, and is suitable for soft water and hard water.
6, good lubricity, and the formula contains unique surfactants and emulsifiers. The lubrication performance is much higher than that of similar products, which obviously reduces the tool cost and improves the surface machining accuracy. It can replace cutting oil and create a good environment for operators.
7. Good chip settling performance. The oil-discharging formula has good chip settling performance, can provide rapid chip settling and cutting subdivision, keeps the system clean, is easy to clean and remove pollutants, and the floating oil can be quickly and completely separated on the cutting fluid surface.
8, good cooling and washing, good cooling and cleaning, keep the machine tool and workpiece clean, reduce the residue of sticky things.
9, highly concentrated, diluted with water 20-30 times, can be used normally.
2. Filter and purify cutting fluid
Swedish brand Alfa Laval Alfa? Laval Alfie500 high-speed centrifuge is suitable for the separation and purification of cutting fluid. Compact high-speed centrifuge can quickly purify cutting fluid, reduce operating cost, improve product quality, reduce maintenance time and reduce environmental impact. This centrifuge is a compact mobile system, suitable for small-scale applications; It can prolong the service life of cooling fluid, reduce the treatment cost, remove impurity oil and solid particles in cutting fluid, prevent tool wear and reduce the consumption of cutting fluid.
