The purity of high-purity aluminum ingots is as high as 99.99%, and the viscosity is large. It is not easy to cut, high energy consumption, high noise, unstable high-speed feed, and problems such as pinching and teething. These problems can cause high equipment downtime. The large number of spare parts consumed, especially the large loss of saw blade, will increase the processing cost and at the same time increase the labor intensity of the operator. Under the condition of cutting fluid, the high-precision sawing process requirements for high-purity aluminum ingots can no longer be met, and a large number of cutting fluids seriously pollute the environment. Since residual cutting fluids of the sawing ingots are likely to cause quality defects of the products when they are returned, The use of cutting fluid for sawing lubrication is not sustainable.
The new micro-lubrication method has its own unique features, it does not need to be cleaned after sawing, and the lubricant used for cutting has a very good biological degradation characteristics, not only in the sawing process to ensure the processing accuracy and the surface quality of the sawing section. It also effectively reduces the wear of the saw blade, which greatly reduces the loss of the saw blade. The principle of sawing the micro-lubrication system is to use the micro-plunger pump to deliver the precise amount of lubricating oil to the U-shaped nozzle arranged on the saw blade, and spray the high-speed compressed air at the cutting kerf and the friction generating part in the saw blade. An oil film is formed between the aluminum ingot to reduce the generation of frictional heat, and high-speed compressed air can not only take away the heat of cutting, but also blow away the debris. The large oil droplets ejected at high speed are not atomized, so the oil and gas mixture will not diffuse in the air and affect the production environment. The oil film formed by the used lubricating oil has strong adhesion and will not be separated due to the high-speed centrifugal force. Saw blades enable lubrication cooling and guarantee the surface quality of the saw section. In this case, the position of the nozzle arrangement also needs to be as close to the cutting area as possible, and the number of nozzles also needs to be changed according to the blade diameter.
The size of the oil droplets and the degree of aggregation on the saw blade have a direct impact on the formation and lubrication of the lubricating film of the saw blade. The factors affecting the oil droplet particles include the pressure, flow rate, and the amount of lubricating oil of the compressed air. Focus on the distance between the nozzle and so on. Therefore, in the production of stable compressed air pressure and reasonable adjustment of the amount and lubricating oil supply in the unit of time in order to obtain good oil droplets. The setting of the oil feeding frequency determines the consumption of oil. The principle of oil feeding is to supply less oil at a single time, and increase the oil volume by increasing the frequency. Saw-cut micro-lubrication can not only exert the performance of the sawing equipment, but also cause no waste. The application of high-purity aluminum ingots for micro-lubrication of sawing processes shows excellent lubricating properties, and further improves the machining efficiency and processing quality on the basis of the existing processes. The problem of rapid wear of the saw blade caused by using the cutting fluid is solved, the service life of the saw blade is prolonged, and the saw blade consumption cost is reduced. Also avoiding the cutting fluid water vapor harms the electrical system.
