Key Points of WEDM Dielectric Working Fluid
Efficient rust prevention, super lubrication, better cooling, can significantly improve processing efficiency and processing accuracy, have good processing effect on non-ferrous metals such as copper and aluminum, prolong the service life of wire cut machines, and can be used for a long time, not easy to spoil , so as to greatly improve the quality and reduce the cost for customers. There are the following advantages:
1. About lubricity
The lubricating effect of the water-based cutting fluid in the cutting process can reduce the friction between the machined surfaces of the molybdenum wire and form a part of the lubricating film, thereby reducing the friction and power consumption, and reducing the surface temperature and the surface temperature of the friction part between the molybdenum wire and the workpiece blank. Wear and improve the cutting performance of the workpiece material.
2. About cooling
The cooling effect of the water-based cutting fluid is to take away the heat energy from the cutting workpiece through the convection between it and the molybdenum wire and the workpiece that are heated by cutting, so as to effectively reduce the cutting temperature, reduce the thermal deformation of the workpiece and improve the machining accuracy and efficiency. Molybdenum wire durability. The cooling performance of cutting fluid is related to its thermal conductivity, specific heat, heat of vaporization and viscosity. The thermal conductivity and specific heat of water are higher than those of oil, so the cooling performance of water is better than that of oil.
3. About cleaning properties
In the process of metal cutting, the cutting fluid is required to have a good cleaning effect. Remove iron powder, oil and sand to prevent contamination of machine tools and workpieces. For oil-based cutting oils, the lower the viscosity, the stronger the cleaning ability, especially the cutting oil containing light components such as kerosene and diesel, the better the permeability and cleaning performance. The water-based cutting fluid containing surfactant has better cleaning effect, because it can form an adsorption film on the surface, prevent particles and sludge from adhering to the workpiece, and at the same time it can penetrate into the interface where particles and sludge adhere, Separate it from the interface and take it away with the cutting fluid to keep the interface clean.
4. About rust resistance
In the process of metal cutting, the workpiece will be corroded by contact with corrosive media such as sludge generated by the decomposition or oxidation of the components of the cutting fluid and the cutting fluid, and the surface of the machine tool parts in contact with the cutting fluid will also be corroded. In addition, when the workpiece is temporarily stored after processing or during the flow between processes, the cutting fluid is also required to have a certain anti-rust ability to prevent the environmental medium and the remaining corrosive substances such as sludge in the cutting fluid from eroding the metal. Especially in wet and rainy areas, more attention should be paid to rust prevention measures between processes.
In addition to the above four functions, Sammlite Machinery’s water-based cutting fluid does not produce precipitation or stratification, oil separation, soap separation and aging during storage and use. It has a certain resistance to bacteria and mold, and is not easy to grow mold and biodegrade, resulting in odor and deterioration. And no damage to painted parts, no harm to the human body, no irritating odor. No smoke, fog or less smoke during use. It is easy to recycle, low pollution, and the discharged waste liquid is easy to handle. After treatment, it can meet the industrial sewage discharge standard. Why don’t you choose it?
