What is the function of CNC cutting fluid

What is the function of CNC cutting fluidCutting fluid is essential for CNC machining. It can not only lubricate the friction between the tool and the workpiece, but also reduce the wear of the tool. Cutting fluid is an important supporting material for metal cutting. The history of human use of cutting fluid can be traced back to ancient times. People know that watering can improve efficiency and quality when grinding stone, bronze and ironware. In ancient Rome, olive oil was used when turning piston pump castings. In the 16th century, tallow and water solvents were used to polish metal armor. Beginning with the successful development of a boring machine by J. Wilkinson in 1775 in order to process the cylinder of a Watt steam engine, the application of water and oil in metal cutting was accompanied. After a long period of development in 1860, various machine tools such as turning, milling, planing, grinding, gear processing and thread processing appeared one after another, which also marked the beginning of large-scale application of cutting fluids. In the 1880s, American scientists had already carried out the first evaluation of cutting fluid. Long-term use will cause bacteria to grow in the cutting fluid, produce odor and make the workshop environment worse. Mainly, the guide rail oil of the machine tool is dripping in the cutting fluid. The cutting fluid will become turbid when mixed together for a long time and produce bacteria. Then do you want to change the cutting fluid? Selection and maintenance of cutting fluid For the grinding process, the grinding after grinding is very small, and a lot of heat will be generated during the grinding process. Therefore, when choosing a cutting fluid, it is necessary to consider both the lubrication and cold cutting performance and the classification of the cutting fluid. Oil-based cutting fluid, water-based cutting fluid, antifreeze cutting fluid, antirust cutting fluid, semi-synthetic cutting fluid, Jinwei emulsion cutting fluid, extreme pressure microemulsion cutting fluid,

Discovered and clarified the phenomenon and mechanism that the use of a pump to supply the sodium carbonate aqueous solution can increase the cutting speed by 30% to 40%. As the tool material used at that time was carbon tool steel, and the main function of the cutting fluid was cooling, the term "coolant" was proposed. Since then, people have referred to cutting fluids as cooling lubricants. Grinding is widely used in the machinery manufacturing industry. After heat treatment and quenching of carbon tool steel and carburizing and quenching steel parts, a large number of relatively regularly arranged cracks often appear on the surface that is basically perpendicular to the grinding direction during grinding. --Grinding cracks, which not only affect the appearance of the parts, but also directly affect the quality of the parts.
First, long-term use not only produces bacteria and makes the workshop environment poor, it is easy to block the waterway and cause damage to the water pump. The waste slag powder contained in the cutting fluid cannot be effectively filtered out, and the powder of the cutting fluid will affect the finish of the machined surface.
Second, the cutting fluid becomes turbid after long-term use. Cutting fluid loss requires adding new fluid without cleaning up the old fluid. Direct addition of new fluid cannot effectively remove bacteria. Long-term exposure to cutting fluid will cause damage to the skin.
The cutting fluid must be replaced if it has been used for a long time. Then, a new stock solution needs to be added for a replacement. How to deal with waste liquid?
Cryogenic distillation and membrane filtration equipment is a purification of waste liquid. Let the water in it be restored. The restored water quality meets the national industrial water A-level discharge standard.
