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

Engine manufacturers’ demand for high-quality base oil will increase


The countermeasures of the oil refining industry used to be to improve oil additives. The current method is to improve the quality of the base oil while improving the additives. One is to increase the purity of the base oil, and the other is to increase the viscosity index of the base oil. The specific requirements for the quality of the base oil are: high viscosity index, long life, that is, high oxidation stability, requiring little increase in viscosity during use, less loss of additives, and less precipitation generation; low volatility, that is, high boiling point, low Fuel consumption; lower viscosity at low temperature, that is, better cryogenic pump delivery performance; high shear stability, less dependent on viscosity modifiers.

Since the hydrogenated base oil has better isomerism and saturation, it has better oxidation stability, better thermal stability, higher viscosity index and lower pour point, and has better low temperature Fluidity, with proper blending performance. òClass base oil, because it adopts heterogeneous dewaxing to selectively convert wax into lubricating oil, so that it has good low-temperature performance, and is more suitable for preparing internal combustion engine oil, automobile automatic transmission fluid and hydraulic oil.

In addition to the production of Type II base oils, part of Type ó base oils can also be produced by adopting the full hydrogenation process. Class ó base oil has all the advantages of Class II base oil, and it also has a higher viscosity index and very low volatility. Its low temperature performance is much better than ò Class oil, close to synthetic lubricating oil (poly A-olefin). Engine manufacturers have higher and higher requirements for the quality of future base oils, and the demand for high-quality base oils will increase.
