Today brings you dry goods for everyone. The most comprehensive maintenance cycle for auto parts in history is shared with everyone. Today, we will first talk about oil and water. 1ã€Oil oil Mineral oil, time period: 6 months, mileage period: 5000 km. Synthetic motor oil, time period: 8 months, mileage period: 8000-10000 km. The time and mileage are subject to first arrival. About 3000 kilometers check whether the engine oil is missing. Volkswagen owners are not included. It is recommended that the trunk reserve two barrels of oil. As for the reason you know. 2, brake oil Time period: 2 years; Mileage period: 40,000 kilometers. The replacement cycle is not fixed, and it may not matter if the time is longer. However, the brake fluid has water absorption and is greatly affected by the environmental humidity. Failure to replace it for a long time will directly lead to a reduction in braking performance. 3, booster oil Time period: 4 years; mileage period 40000 km. Can be used for a long period of time, subject to time, but need to pay attention to the replacement, help oil is corrosive. 4ã€Transmission oil Manual gearbox, time period: 5 years; mileage period: 100,000 kilometers. Automatic transmission, time period: 3 years; mileage period: 60,000 kilometers. Transmission oil is also based on time and mileage first. 5, differential oil 60000 kilometers or 3 years. However, it should be checked according to the time cycle, because impurities will be mixed into the differential oil for a long time. 6, antifreeze Time period: 2 years; Mileage period: 40,000 kilometers. It is also based on time and mileage first arrival, but in the winter period it is necessary to diligently check for lack of, and the other is that different antifreeze can not be mixed. Sheet metal fabrication processing is formed by laser cutting or stamping process, shear and bending, bending, bending, welding, riveting. The Sheet metal fabrication used are cold-rolled plate (SPCC), hot-rolled plate, galvanized plate (SHCC) (SECC, SGCC), copper (CU) brass, copper, beryllium copper, aluminum (5052), stainless steel. Sheet metal fabrication processing steps: according to the parts drawing (3D) expanded into a plan (2D), laser cutting or die stamping shape, CNC punching each bending part, should pay attention to the direction of the burr of the workpiece. Then the students are welded or riveted (some). Surface treatment after processing: electroplating, passivation, sand blasting (powder), anode treatment. Products are generally made for the connection and the outer cover. Applications in robotics, drone, communications, medical devices, industrial automation equipment.
