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

How to properly protect the sealing performance of the car

 

In the hot summer weather, spontaneous combustion of vehicles caused by oil circuits and electrical circuits often occurs, which often causes the vehicles to be scrapped and sometimes even endangers personal safety. In this regard, fire protection professionals proposed that “cleaning in the cabin” can prevent spontaneous combustion, and specifically gave two key preventive measures.

A few days ago, in front of the business department of China Merchants Bank, Zhongshan Road, Heping District, Shenyang City, Liaoning Province, a black smoke suddenly appeared from the engine compartment of a silver-gray car, and then spontaneously ignited. After the firefighters rushed to the scene, they reminded the car owner to “don’t open the car cover yet”, and helped extinguish the fire, but the car was basically scrapped.

The reporter learned from the Shenyang Fire Brigade that since May, the temperature has risen significantly, and spontaneous combustion of vehicles has begun to increase. In just half a month, 36 car fire accidents have occurred in the city, which is the highest in the past year. At present, most common automobile spontaneous combustion incidents are caused by short circuits in high-temperature weather, and the probability of occurrence is more than 60%; the second is the oil circuit problem. A recent change is that spontaneous combustion incidents caused by car decoration have also begun to increase.

Sun Guofeng, a senior engineer of the Shenyang Fire Fighting Detachment, believes that there are two main causes of vehicle spontaneous combustion. One is the short circuit caused by the aging of the circuit. A large part of the spontaneous combustion accidents are caused by fire in the engine compartment. Connection, etc. caused by short circuit and fire. Another cause is the aging of the oil circuit leading to a fire. Because some oil leakage and oil leakage in the engine room have not been detected in time, the temperature in the engine room rises sharply in the summer high temperature environment, which is enough to ignite the leaking oil and cause the risk of spontaneous combustion. “‘Cabin cleaning’ can prevent spontaneous combustion. For short circuits caused by aging of the circuit, the way to avoid it is to develop a good inspection habit and regularly check some circuits in the car; and for the problem of aging oil circuits, wash the car at the same time. It is necessary to clean the dust and oil stains in the engine compartment, and if necessary, go to the repair shop for professional cleaning, so as to discover and eliminate the risks in time." He suggested.
