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

Daily maintenance and care measures for automobile water tanks

If the vehicle’s water tank is not handled properly during normal driving, it is very easy to “boil the pot”. Encountering such a situation will not only delay the owner’s time, but also may cause damage to the machine if it is not handled properly. Today, I will introduce to you the daily maintenance of the water tank and the cooling techniques of the high temperature water tank. I hope it will be helpful to the majority of car owners.

High temperature water tank cooling skills:

When the car is driving, white water vapor suddenly emerges from the engine cover, or the pointer of the water temperature gauge rises to the high temperature “H” mark position, it means that the engine temperature is too high. It is usually caused by insufficient water in the water tank, water leakage, or failure of the fan in the water tank.

The processing method is as follows:

Step 1: Find a safe place to park immediately, but don’t turn off the engine immediately. Let the engine keep idling to continue to dissipate heat, and at the same time open the engine cover to increase the heat dissipating speed.

Note: When the water temperature is too high or even boiling:

1. Don’t try to continue driving, so as to avoid major machine damage accidents.

2. Don’t try to open the water tank cover, otherwise hot liquid may spray out and cause burns.

3. Do not pour cold water into the engine block and cylinder head, as it is likely to cause the cylinder block to burst due to sudden cooling.

Step 2: After a period of time, check for water leaks under the car.

Step 3: Wait until the water temperature gauge pointer drops to the proper temperature position, then turn off the engine.

Step 4: Wrap the water tank cover with a wet towel, slowly turn on the ** switch (about 1/4 turn), after the water vapor pressure is released, fully open the water tank cover, check the water volume and quality in the water tank, and the fan belt Are there any exceptions? If the amount of water is insufficient, you should slowly add water to the vicinity of the *high mark.

Note: If the water tank is leaking or the fan belt is loose or broken, you can call the towing company and wait for the trailer to be rescued. If necessary, you can also wait for the engine to cool down completely and then drive the car to a service shop for repairs at a low speed. Remember, you cannot drive at normal speed, otherwise it is likely to cause permanent damage to the engine.

Daily maintenance method:

Generally speaking, the antifreeze should be replaced after driving 20,000 kilometers or one year; when there is no antifreeze, never add tap water. Rust and fouling of the engine water tank are the most common problems. Rust and scale will restrict the flow of antifreeze in the cooling system, reduce heat dissipation, cause the engine to overheat, and even cause engine damage. Antifreeze oxidation will also form acidic substances, which will corrode the metal parts of the water tank, causing damage and leakage of the water tank. The solution to the water tank failure is mainly the routine inspection on weekdays. The water tank should be checked frequently for leaks or rust. It should be cleaned, replaced or added with antifreeze to increase the boiling point and prolong the service life. Generally speaking, the antifreeze should be replaced after driving 20,000 kilometers or one year. This can increase the boiling point, prevent the generation of scale, rust, and improve the heat dissipation effect, so that the water pump has a lubricating effect, and avoids and eliminates the engine damage caused by the instant high temperature caused by the bubbles.
