What errors may occur during CNC machining and CNC machining​?

 CNC machining and numerical control machining are a method to control the movement of machine tools and the production process of machining through computer digitization and information digitization. It is an intelligent numerical control device developed as an economical, high-speed, reliable, multi-functional, intelligent, and open structure. CNC machining is also an important indicator that can measure the continuous level and comprehensive ability of a safety technology, as well as the degree of modernization of related science and technology capabilities, especially in aviation, biology, medical and other high-tech cultural industries, and it is also a powerful indicator. reflect. So, what errors may occur during CNC machining and CNC machining? Let us understand together:   The use of approximate machining motion or approximate tool contours causes errors in the CNC principle of machining. The reason why it is called machining principle error is because of the error in machining

What are the rules for metal stamping die scrap tube?

The Purpose Standardize the management of the scrapping of the company's metal stamping dies, prevent the loss of company assets, and formulate this system specially. Scope of application It is suitable for the management of the company's scrap molds. Definition If the molds listed in the assets of the company fall under one of the following circumstances, the use management department may apply for scrapping. 1. Molds that exceed the specified service life. 2. The mold is severely damaged by accidents or accidents, and molds that cannot be repaired or have no repair value. 3. Metal stamping dies that have not reached the service life, but due to safety, quality, efficiency and other issues, the repair still fails to meet the minimum requirements of the customer's product process or affects the production safety and efficiency. 4. Product customers have stopped placing orders or have not placed orders for molds in several years. 4. Responsibilities 1. Responsibilities of th

Structure and function of fuel filter

 

The structure and function of fuel filter

The structure of the fuel burner is composed of an aluminum shell and a stainless steel bracket. The bracket is equipped with a high-efficiency filter paper assembly. The filter paper is seen as a chrysanthemum to increase the flow area. The EFI filter cannot be combined with the carburetor. The filter is universal. Because the EFI filter often bears the fuel pressure of 200~300kPa. Therefore, the pressure strength of the filter is generally required to reach more than 500kPa, and the filter of the carburetor cannot meet the requirements.

The function of the fuel filter is to remove the iron oxide, dust and other solid impurities contained in the fuel, prevent the fuel system from clogging, reduce mechanical wear, ensure stable engine operation, and improve reliability.

Fuel filter replacement instructions

The fuel filter must be replaced every 30,000 kilometers. If the fuel impurity content is large, the driving distance should be shortened accordingly. The arrow on the fuel filter housing indicates the direction of fuel flow. When installing the fuel filter, it is not allowed to install it upside down. Even if it works in the flip-chip state for a short time, it must be replaced.

The recommended replacement cycle of automobile fuel filters should vary according to their own structure, performance and purpose, and cannot be generalized. If the filter is installed in the fuel line, it is called an external filter (external); conversely, the internal filter (internal) refers to the filter installed inside the fuel pump and fuel tank. Among them, the fuel tank filter or its protective sleeve is generally considered to be a maintenance-free component.

Many imported cars use banjofittings for fuel filters. In order to ensure the reliability of the connection and sealing, the same gasket must not be used repeatedly. In addition, even if a brand-new gasket is used, the tightness of the connection must be checked. When the fuel system needs to replace the o-ring, it is necessary to ensure that the specifications and models of the o-ring are correct, and to check whether the elasticity and hardness of the ring are appropriate.

The fuel system without loop has only one internal filter (in the fuel tank). Although this all-in-one pump, filter, and delivery unit are expensive, when the fuel delivery is blocked or When the performance of the engine decreases due to this, proper maintenance and maintenance must be carried out in time. At the same time, it is necessary to check all the faults in the fuel line and the rupture and curling of the hose clamp.

Most car manufacturers recommend a replacement period of 48,000 km for normal maintenance of their external filters; the recommended replacement period for conservative car repair and maintenance is 192,000 to 24,000 km. If you are in doubt, please refer to the owner's manual to find the correct one. Recommended replacement cycle. In addition, when the filter hose has aging or cracks caused by dirt, oil and other dirt, the hose needs to be replaced in time.
