Water-soluble cutting fluid is an indispensable processing medium in the metal processing process. It can not only improve the cooling and lubrication of automobiles, aerospace, machinery and large metal parts, but also significantly prolong the service life of various parts and improve the product quality. Today, I will introduce to you how water-soluble cutting fluids work!
When selecting water-soluble metal cutting fluids, different cutting fluid products should be selected from the different characteristics of different materials. For example, when cutting high-hardness stainless steel, it is necessary to select good extreme pressure performance according to its characteristics of high hardness, high strength, and difficult cutting. Extreme pressure water-soluble metal cutting fluids are used to meet the extreme pressure lubrication performance requirements of cutting fluids in the cutting process; for materials such as aluminum alloys and copper alloys, due to their high toughness and high activity, they are used in the cutting process. When choosing a water-soluble metal cutting fluid, the lubricity and cleaning properties of the cutting fluid are more required, and at the same time, the workpiece cannot be corroded. After the metal cutting fluid is selected, the irritant/toxicity of the cutting fluid product to the human body, service life, waste liquid treatment, etc. should be comprehensively considered, and finally the correct type and concentration of metal cutting fluid should be selected. When choosing water-soluble metal cutting fluid, we must first consider the low irritation and low toxicity of the product to ensure the personal safety of the operator; at the same time, each manufacturer emphasizes the length of the service life of the cutting fluid product, and all require the selection of The water-soluble metal cutting fluid has a relatively long service life to meet the requirements of the factory to reduce the overall cost. Moreover, the long service life of the cutting fluid not only reduces the usage of the water-soluble metal cutting fluid, but also reduces the number of fluid changes. , reduce machine tool downtime, reduce labor costs, and reduce the number and treatment of water-soluble metal cutting fluid waste liquid treatment and the resulting large amount of waste liquid treatment costs; third, with the continuous improvement of environmental protection requirements in various countries , it is required that the waste liquid of water-soluble metal cutting fluid must be treated with waste liquid and meet the national and local three waste discharge standards before it can be discharged. Therefore, when each factory selects water-soluble metal cutting fluid, it is also difficult to treat its waste liquid. Ease of use is included as one of the selection criteria.
According to the characteristics of the use of water-soluble metal cutting fluid, it is inevitable that any water-soluble metal cutting fluid product will have some problems during use; therefore, each user usually takes the supplier's after-sales technical service work as a choice for cutting basis for liquid products. Therefore, after selecting the correct water-soluble metal cutting fluid, we must attach great importance to the effective maintenance and maintenance of the cutting fluid products in use. Usually, a reasonable regular/irregular sampling and testing plan can be determined according to the different use conditions and use environments of water-soluble metal cutting fluids. Through sampling, testing and analysis, we can timely discover or predict that the cutting fluid may or has appeared in the process of use. Problems should be dealt with as soon as possible or preventive measures should be taken to avoid the prominence of problems and bring losses to production. The maintenance and maintenance of water-soluble metal cutting fluid is usually completed by the technical service personnel of the cutting fluid supplier and the user's on-site technicians. It is usually possible to detect the water-soluble metal cutting fluid in use: concentration, PH value, rust resistance, The stability of the cutting fluid (the amount of floating oil/soap after standing), the content of microorganisms (bacteria, fungi, molds, etc.) and the electrical conductivity (or total hardness) of the cutting fluid are evaluated and analyzed to ensure the good use of the cutting fluid. At the same time, since water-soluble metal cutting fluids usually contain surfactants, oily agents, mineral oil and a small amount of water, it requires that the storage period of water-soluble metal cutting fluids should not be too long; Freshness, the supplier's production capacity and supply cycle should also be considered when selecting water-soluble metal cutting fluids. In foreign countries, when selecting water-soluble metal cutting fluids, some developed countries pay more attention to the selection of hazards to human health, waste liquid treatment and comprehensive costs while meeting the requirements of cutting processing; this view gradually Accepted by the domestic metal cutting industry. According to this situation, some well-known foreign companies successively introduced their high-quality water-soluble metal cutting fluid products to China in the late 1980s to meet the requirements of the Chinese market. In short, in the process of metal cutting, water-soluble metal cutting fluid must be used. For our personal health and environmental protection, reduce comprehensive costs and improve benefits; we must consider various aspects, comprehensively analyze, and choose a more Suitable water-soluble metal cutting fluid products.
