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

Market technical analysis of auto parts industry

The state has begun to strengthen macro control over the quality of auto parts, which has promoted the continuous improvement of product quality. For example, in 1992, the Bureau of Technical Supervision issued the “Implementation Measures for the Regulations of the People’s Republic of China on Product Quality Certification”, which was hosted by China National Automobile Industry Corporation, including experts from scientific research units, quality inspection agencies, and production enterprises, and established the China Automotive Product Quality Certification Committee . On behalf of the country, the committee implements quality certification for automotive products, and issues certification certificates, certification certificates, and certification marks. The establishment of the committee has played a catalytic role in improving product quality and reputation, promoting technological progress, ensuring the interests of users and consumers, ensuring personal safety, protecting the ecological environment, saving energy, and promoting international trade. Today’s auto parts market also has worrying problems, mainly including the following points: Compared with the production of complete vehicles, the production of repair parts is lagging behind. Some auto manufacturers are busy assembling new cars and are not on the agenda for the production of repair parts.

Many parts of joint venture vehicles have to be imported from abroad with a large amount of foreign exchange, resulting in long shutdown dates for maintenance vehicles and high maintenance costs. The quality of some parts of the domestically produced joint venture cars is not as high as that of some cars. However, according to users’ reports, some parts of the domestically produced parts are easily damaged. This is mainly due to the introduction of new technologies for vehicle manufacturing since the 1980s, while the parts manufacturing industry introduced fewer new technologies and lacked the necessary support policies. Therefore, domestic auto parts cannot meet the needs of new joint venture vehicles in terms of quantity and quality. Maintenance needs. The macro-control of the parts production industry is weak. The factories that are unable to produce auto parts have no unified technical standards. There are two machine tools and one thatched cottage to produce auto parts. There are no drawings and standards. They are copied with real objects, and the parts produced are not inspected. Get the market to sell, causing counterfeit and inferior auto parts to be repeatedly banned.
