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 daily maintenance rules


The daily tire maintenance should emphasize that the correct air pressure should be maintained when driving. The tire sidewall has the highest air pressure value provided by the car manufacturer, and the air pressure of all tires (including the spare tire) should be checked at least once a month when they are cooled. However, it is not enough to just check. If you find that the air pressure is decreasing too fast, you must find out the reason to avoid leaving hidden dangers and being caught off guard at a certain moment. Staples, cuts, aging and cracking of valve rubber may all be the culprits. If it is a new car, check whether the edge of the rim rim and the tire are in good fit, and whether there has been a water leak check and an air leak test. After finding out the cause, you can find an experienced dealer or a large tire shop to inquire whether it is worth repairing, because behaviors such as nailing will cause damage to the internal structure of the tire, which is not worth continuing to use. In any case, do not exceed the reasonable speed required by driving conditions and legal restrictions. If you encounter obstacles such as rocks, potholes, etc. ahead, you should avoid or pass slowly. Because even if the inflation pressure is correct, at high speeds, if the tire encounters road obstacles, the probability of damage is higher than at low speeds.

The tread of a radial tire has a steel wire belt layer, but the tire side is not covered by a steel wire layer. When driving at a high speed, the tire hits pits and other foreign objects, causing the tire to severely squeeze between the impact object and the rim flange Deformation can cause the cord fabric to break, and the air inside the tire will push up from the broken yarn to form a bulge. Continued use of such a tire will cause more and more yarn breakage, and eventually a puncture. Always check the condition of the tire, including whether there are bulges, cracks, cuts, studs, and abnormal tire wear. Some new cars have not been bought for long, and the tires on both sides of the car wear more on one side and less on the other, or the shoulder wear is faster than the rest of the tread. This is caused by poor tire positioning. Four-wheel positioning should be considered. Even if the vehicle is traveling less than 8,000 kilometers at this time, the tires bought for hundreds of dollars will easily be eaten. Don’t simply change the tire. The vehicle’s own condition will not change, and the new tire will still cause problems. This is as meaningless as changing your shoes instead of having a problem with your feet. If the tire shakes excessively, the wheel may be unbalanced. This situation will not only shorten the life of the tire, but also affect the handling of the vehicle, which may be dangerous. If the tire is worn to the wear indicator, stop using it.

There is a wear indicator at the position of 1.6 mm left in the tread groove. Worn to this mark, it must be replaced. It is dangerous to use tires that exceed the mold consumption indicator, especially when driving on wet ground. Because the pattern is ground, the drainage performance of the tire is greatly reduced, and the tire and the water surface basically form a water-mill state, which hinders the contact between the tire and the ground, and the grip is greatly reduced, which poses a safety hazard. The spare tire should be avoided near sunlight, oil, acid, and hydrocarbons, which will erode the tire. All tires should be stored in a cool, dry and dark room to avoid the danger of moisture accumulating in the tires. Due to pressurization, liquid may enter the carcass layer through the inner liner of the tire, which can cause sudden damage to the tire. When buying tires, the storage environment of tires can also be used as an aspect of inspecting tire shops.
