Development trend of industrial gear oil: the improvement of gear box manufacturing technology and the specification evolution of industrial gear oil are two major factors affecting the development trend of industrial gear oil. 1. Development of Industrial Gear Equipment With the rapid development of the gear industry, the industrial gearbox is developing towards greater power, higher load and smaller volume, and the working environment is humid. The increase of the load increases the contact pressure of the tooth surface and the wear and pitting between metals; The reduction of gearbox volume means that there is less oil for lubricating gears and bearings, which will lead to the increase of oil temperature and accelerate the oxidation of oil. The sludge generated in the oxidation process will shorten the service life of oil and gearbox components; 2. Evolution of Industrial Gear Oil Specifications AIST 224 standard has always represented the highest specification of industrial gear oil, and the quality of L-CKD gear oil in the national standard GB 5903-2011 Industrial Closed Gear Oil formulated in China has reached this standard. In addition, the commonly used industrial gear oil specifications include the national standard ISO 12925, AGMA 9005-E02 EP in North America, and DIN51517-3 in Europe. From the above development of industrial gear manufacturing and industrial gear oil specifications, the future industrial gear oil should not only have good tribological properties, but also meet the r

The unique tools and aluminum alloy materials of the mobile phone case are specifically used in the shell, the middle frame, the card, the side button, and the back cover processing. Battle 1: Aluminum alloy materials are endless. The traditional one is 1 series, 5 series, 6 series, 7 series, in order to be satisfied with high strength, high end, high end oxidation, the effect of stamping, and the effect of oxygen. The corresponding cutting fluid may be developed in a timely manner according to the different aluminum alloy to meet the requirements of different materials. Battle 2: Fine diecasting has achieved great development in recent years. The working hours of CNC processing CNC processing are too long. For example, a middle frame is sometimes consumed by half an hour, the process is single, and the interior can be formed in a single. Cracks, the appearance cannot be performed with outstanding anode oxidation. The golden plastic co -surface will constitute the spraying process more complicated and the yield rate is low. But it also got gratifying development. 1. The continuous optimization of fine die casting technology, Guangdong's die casting industry is extremely prosperous. Mold use.
