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 rapid development of the domestic automobile industry has driven the lubricant market

 

As the rapid development of the domestic automobile industry has driven the rapid growth of the lubricant market, from the perspective of the product structure of the production plant, it mainly produces three oil series of internal combustion engine oil, hydraulic oil and gear oil, and its output accounts for the total output. This also reflects the current consumption structure of lubricants in China. From the quality point of view, although the proportion of medium and high-end lubricants in China has been steadily increasing in recent years, the proportion of medium and high-grade products in finished lubricants is basically, but the proportion is still far from that of developed countries. Demand forecast The lubricating oil market is closely related to the demand for oil in industries such as automobiles, machinery, and transportation. The entire machinery industry accounts for a quarter of the national industrial output value. The development and progress of the machinery industry is accelerating, requiring high-grade lubricants that meet the requirements of high mechanical load, long life, low fuel consumption, energy saving and environmental protection.

According to the development plan of the relevant department, combined with the investigation of the department’s oil equipment, the domestic demand for lubricants. The development of lubricants in China High-quality base oils are the basis for the production of high-end lubricants. The base oils are mainly vacuum wax oil, catalytic wax oil, hydrogenation tail oil and other widely used distillate oils. These distillate oils can be used as lubricating base oils, as well as high-quality catalytic feeds, reforming materials and ethylene raw materials. . Most domestic lubricants are produced in large refineries, and their base oil supply is optimized to provide the most reasonable fractions after optimizing the crude oil processing process. However, a considerable number of lubricant manufacturers rely on outsourced base oil production. Because refineries will not specifically optimize the process for them, it is difficult for such lubricant plants to purchase high-quality base oil raw materials. This is also China’s low-grade lubricants. One of the main reasons at present.

Crude oil is a low-pour-point naphthenic crude oil with low sulfur and low wax content. The lubricating oil produced has a low viscosity index. It has the characteristics of heavy distillate, high density, high viscosity, low freezing point, etc. It is the best raw material for the production of some special lubricants. The low freezing point naphthenic lubricants produced with it can be used as electrical oils and refrigeration oils. , Rubber industry oil, cylinder oil and lubricating grease, etc. The lubricating base oil of crude oil not only has a higher yield than paraffin-based base oil, but also has a shorter process, resulting in lower production costs than paraffin-based base oils. The raw material of lubricating oil base oil produced by crude oil is not only of good quality, but also of low cost, which has strong market competitiveness. China's oil resources are becoming increasingly scarce. How to use resources reasonably and effectively based on the quality of China's crude oil is a problem worthy of study and optimization.
