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

The progress of automobile manufacturing technology and the stricter environmental protection indicators

The technicality, complexity and particularity of lubricating oil products fully reflect the necessity of lubricating oil technical service work, which is embodied in the following aspects: Lubricating oil is a product with high technical content, and its product development and application research involve petrochemicals and machinery. Professional and other multi-disciplinary fields, cross-professional, cross-industry proficiency in lubricant expertise is not easy; any mechanical design must carry out a reasonable lubrication design, and any application of any kind of oil has problems. However, the lubricating oil market is wide-ranging, with many types of user industries, and users are in a state of dissociation and dispersal. It is necessary to establish a large number of expert service teams; there are many varieties of lubricating oils, and the specifications and grades are complex.

China has formulated lubricating oil classification standards with reference to international standards. Lubricants are divided into 19 categories according to application occasions. Each category 1 oil product is divided into several varieties. For example, E category internal combustion engine oil includes gasoline engine oil, diesel engine oil, railway internal combustion engine oil, and marine cylinder oil. , Medium-speed cylindrical diesel engine oil, two-stroke gasoline engine oil, etc. In the internal combustion engine oil, there are single-grade oil, multi-grade oil, and general-purpose oil. There are about a hundred brands in such a combination. Without certain lubricant business knowledge, it is difficult to choose suitable lubricants; due to the advancement of automobile manufacturing technology And environmental protection indicators are becoming more and more stringent. Lubricants, especially internal combustion engine oil, have become the fastest replacement products in the petrochemical industry. Compared with developed countries, China’s oil grade is quite different. The demand for lubricants in developed countries has a very small span. Only two grades of lubricants coexist in the United States, and only three grades of lubricants coexist in Europe. Taking gasoline engine oil as an example, China has the highest grade SL grade gasoline engine oil. There are also SC and even SA and SB grade gasoline engine oils, with a difference of seven or eight grades. Due to the country's insufficient enforcement of oil quality grades and users do not understand the basic knowledge that upgraded products can replace original oil products, it is difficult to promote new upgraded products and cannot use oil and oil products as in industrialized developed countries.
