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

It is very important to replace the lubricating oil in winter car maintenance

  As the weather turns cooler, ordinary lubricating oils will become thicker at low temperatures, and their fluidity will be weakened, making it difficult to start the vehicle and increasing wear and tear.Therefore, car owners who use ordinary lubricating oil must not forget to change the oil in their car.
  General lubricants are**
  The lubricating oil should be selected according to the requirements of the engine. You can neither use too high-grade engine oil on engines with lower requirements, nor use lower-grade engine oil on engines with higher requirements.The choice of lubricating oil can be increased by one level on the basis of the manufacturer’s recommendation, or the performance of synthetic engine oil is better.
  In addition, motor oils for winter and summer are now available on the market.The general-purpose engine oil can maintain stable lubrication performance no matter how the temperature changes, and has a better protective effect on the engine.Therefore, this oil is the best choice.
  If the engine is new or in good condition, use low-viscosity oil as much as possible, such as 0W-40, 5W-40, and 10W-40, so as to make the lubricating oil flow faster and reduce the wear when starting.If it is in the high temperature season or the engine has worn to a certain degree, it is necessary to choose high-viscosity oil, such as 15W-50, etc., which is conducive to forming a thicker oil film, maintaining oil pressure, and reducing oil consumption.
  No need to add additives in lubricating oil
  Experts said that it is generally not recommended to add additives to lubricating oil.Because the lubricating oil itself is composed of base oil and additives, its formulation has been tested and screened.Adding additives may be counterproductive, not only reducing the original cleaning and anti-wear functions of the lubricating oil, but also increasing sludge and carbon deposits, affecting the performance and service life of the engine.
  Professionals remind that when replacing the lubricating oil, the lubricating oil filter element generally needs to be replaced, so that the newly replaced lubricating oil can perform better.Lubricant products of different brands cannot be mixed.
  There are tricks to distinguish good from bad
  At present, there are many fake products on the market. Many car owners can’t distinguish the quality of lubricating oil. Now I will teach you a few tricks. **To observe.If the oil is clear and yellowish-brown, it means its quality is good; if the color is turbid or emulsified, it means that it contains more water; if the oil has a burning smell, it means that it is prematurely oxidized or mixed with other oils.The second is to check if there is any sediment. It is definitely not a good oil.Third, you can drop the engine oil on the iron plate or exhaust pipe above 110°C. If there is a popping sound, it means that the engine oil contains moisture.
  In fact, the *insurance is to go to a designated dealer, a major brand gas station or a repair shop to purchase or change the oil.
