Machine tool maintenance of cutting fluid and rail oil use

Machine tool maintenance of cutting fluid and rail oil use, 2020 - 09 - The main performance is: 02 cutting fluid cooling and lubrication, anti-rust, cleaning, etc. , these performance are implemented by the different effects of additive, have a plenty of lubrication effect, have a plenty of antirust effect, and the sterilization bacteriostasis, eliminate the bubble effect. Although the above several kinds of additives is very important, but they are many components of the oil phase, the temper is very big, have a plenty of don't mix with each other, have a plenty of insoluble in water. While the new purchases of cutting fluid concentrate, is must to use the water. So we'd like to introduce the following special additives, without it, emulsion concentrate hard and finally into the stable cutting fluid, all cutting fluid performance will become floating clouds, it is called 'emulsifier. The effect of emulsifying agent is to get the composition of undissolved or poorly soluble in water, each other can 'harmonization in harmony like milk. All kinds of additives in cutting fluid, uniform and stable distribution can form we need any dilution of cutting fluid. Rail oil also should have good lubrication performance, rust resistance, anti-wear performance ( Is overloaded cases, the lubricating oil film is not squeezed out the performance of crushed) And there is a very important performance, is the demulsification performance. An emulsion, a demulsification. When cutting fluid met rail oil, rail oil of effective components, and the emulsion emulsified cutting fluid out guide face no protection, no lubrication, no rust '3 without state, how to do? Modern machining workshop, the choice of the guide rail oil is very important. Rail oil to machining precision and influence the service life of metalworking fluid, and thus directly affect the production efficiency of machine tool. The ideal guide rail oil requires not only have excellent friction control, also should be commonly used in the manufacturing process of metal between water soluble cutting fluid maintained the separability of excellence. If choose rail oil and cutting fluid cannot be completely separated, guide rail will be emulsified oil, or cutting fluid performance will be poor, this is the modern machine tool guideway corrosion and two major cause of guide rail lubrication effect is poor. Meet cutting fluid for machining, rail oil, there is only one mission, let them 'from'! Therefore, choosing rail oil and cutting fluid, shall be effective for both the separability of evaluation and test. Correctly evaluate and measure the separability of the two, to avoid losses in the process of the actual processing, the accurate operation of mechanical processing equipment, undoubtedly has a pivotal role. Demulsification test: test for simulating rail oil pollution phenomenon of cutting fluid. Experiment, the container into 90 ml of cutting fluid and 10 ml of guide rail oil, vertical mixing them 15 seconds, again in 16 hours of time to observe the condition of the liquid in the container, the container and to measure the top, middle, bottom three liquid solvents ( In ml) : separating rail oil ( At the top) , 'mixture and separation after cutting fluid ( At the bottom) 。 Such as records of test results for 90/0/10 ( 90 ml of cutting fluid, 0 ml mixture, 10 ml of rail oil) , which shows that oil and cutting fluid to achieve 'separate'; If the result is 98/2/0 ( 98 ml of cutting fluid, 2 ml of mixture, 0 ml of rail oil) , it means that the emulsified reaction, cutting fluid and rail oil was not well separated. Cutting fluid separability experiment: the experiment of water-soluble cutting fluid pollution to simulate the phenomenon of rail oil. In a ratio of 80/20, the guide rail oil blended with a variety of conventional cutting fluid respectively, 8 ml of guide rail oil, cutting fluid, 2 ml. At 1500 RPM speed mix to stir for 1 minute, then respectively after 1 hour, 1 day, 7 days visual state of the mixture. According to the following standards for 1 - the state of the mixture Level 6 grade: 1 = completely separate part 2 = 3 = oil separation + + 4 = oil mixture middle middle mixture ( + cutting fluid) Among 5 = mixture + 6 = cutting fluid for middle mixture, of course, all identified rail oil and the separation of the cutting fluid does not mean that once and for all. In the process of equipment operation, there are still many uncontrollable factors on the guide rail oil, and the performance impact of cutting fluid, these also cannot be ignored. Daily maintenance and maintenance work and ensure efficient operation of one of the key factors. Good maintenance: in addition to the rail oil, other machine lubricating oil, such as hydraulic oil, gear oil, etc. Can also cause pollution. Regular maintenance is essential, therefore, to prevent caused by different machine tool cutting fluid contact oil pollution, prevent hyperplasia of anaerobic bacteria in the cutting fluid, and then to keep the good performance of the cutting fluid, prolong its service life, and reduce the odor. Cutting fluid performance monitoring: using refractometer regular monitoring of the concentration of the cutting fluid, under normal circumstances, refractometer will appear a thin line. But if more emulsified cutting fluid can contain guide rail oil, after the fine lines on the refractometer will become fuzzy, this means that the oil content is higher. Or, by titration method to measure the concentration of the cutting fluid, and the results compared with the concentration of fresh cutting fluid, also can draw oil emulsification degree. Remove oil: many modern machine tools have been equipped with automatic oil separator, or to separate add oil separator equipment. In large systems, commonly used filter and centrifuge to remove oil and other contaminants. In addition, you can use the tools such as industrial vacuum cleaner manually remove oil. （ Source: web)
