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

Tire rotation can extend the life of the spare tire and also has a shelf life


Many car owners will take their families out for self-driving tours, and the tires of their cars are also showing varying degrees of wear and tear, and many car owners are a little confused about the replacement of the tires.

Tire rotation can prolong life

I learned from many car 4S shops that now car owners are very careful about car maintenance, but many car owners think of changing tires when they encounter problems. In fact, it takes a lot of money to change tires frequently. In many cases, tire replacement is just a matter of cost. It can prolong the life of the tire, and the reasonable rotation can extend the life of the tire by 20%. It saves a lot of money for the owner.

The after-sales service manager of the Dongfeng Nissan franchise store, Wang? This Dan? Hemorrhoids ㄆ诨毨? ldquo;Rotation” is to ensure that each tire reaches the balance of work intensity. However, the tire replacement is also regular and cannot be arbitrarily. Change location.

Generally speaking, there are two ways to change tires. The first way is to swap front left tires and rear left tires, and swap front right tires and rear right tires; the second way is cross swapping, which means Change the left front tire to the right rear tire and the right front tire to the left rear tire. Relatively speaking, the second method is better.

As for the number of kilometers to be exchanged, the “Vehicle User Manual” of some models recommends that front-wheel drive vehicles should be changed every 8000 kilometers, while four-wheel drive vehicles need to be changed every 6000 kilometers. However, if there is no rotation for more than 20,000 kilometers, and tire wear has formed, it is not recommended to perform tire rotation to avoid deviation. But the king?

Now, in the process of using a car, most consumers don’t pay much attention to the spare tire, and they always think of the spare tire when the car tire is punctured or punctured. In fact, it is worth paying attention to consumers that if the specifications and structure of the spare tire are the same as the tires normally used on the car, the *scientific* reasonable method is to cross-rotate the spare tire together. In this way, a car will run 5~10. After 10,000 kilometers, the 5 tires (including the spare tire) wear very uniformly and can be replaced directly without wasting the spare tire.

However, because tires also have a shelf life, consumers must check the condition of the spare tire before using the spare tire. After all, the tire is a rubber product. If the spare tire is left for many years, it may crack. It is understood that, generally speaking, the shelf life of tires is calculated from the date of leaving the factory, which is about 5 years. Expired tires cannot be used anymore. Consumers should not be afraid of waste and should dispose of expired tires in time.
