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

To obtain a high viscosity index base oil product has a reasonable distribution in composition

Since the sulfur element is mainly concentrated in the macromolecular polycyclic polar aromatics, when the aromatics content in the base oil is very low, most of the sulfur has been removed, so the sulfur content generally meets the index requirements. The viscosity index is related to the saturated hydrocarbon content in the base oil, but it is not a simple linear relationship, but is determined by the total amount of saturated hydrocarbons and the ring distribution of paraffins, cycloalkanes and cycloalkanes that constitute saturated hydrocarbons. .

In order to obtain base oil products with high viscosity index, in addition to the higher saturated hydrocarbon content of the base oil, the saturated hydrocarbons should also have a reasonable distribution in the composition of paraffins and naphthenes, in order to achieve the goal. To further increase the saturated hydrocarbon content in the base oil, it can be achieved by increasing the reaction depth and reducing the aromatic content. However, from the reaction point of view, the saturated hydrocarbon conversion reaction has become the main reaction in the system. A large amount of saturated hydrocarbons are converted, which will greatly reduce the yield of lubricating oil fractions and even reduce the viscosity grade of the base oil product.

If the method of controlling the aromatics content in the hydrotreating feed is adopted, it can not only ensure the full conversion of aromatics, but also prevent the excessive cracking of saturated hydrocarbons, so that the goals of increasing the viscosity index and reducing the aromatics content can be guaranteed at the same time. Therefore, in the lubricating oil medium pressure hydrotreating process, in order to obtain high-yield and high-quality products, it is necessary not only to carefully select the appropriate pressure, temperature, catalyst and other conditions, but also to properly control the aromatic content in the feed to ensure high An important factor for quality and high yield base oil products.
