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

Summer is coming, car tires are very important to cool down and prevent heatstroke

Since the fall, the high temperature has continued, and the surface temperature in the afternoon is as high as 50 or 60 degrees Celsius, which has caused great discomfort to people and also brought many safety hazards to the car. To this end, the Beijing The Municipal Meteorological Bureau has launched popular science videos to remind citizens that cars should also prevent “heatstroke” in the hot summer.

First of all, summer is a period of high incidence of car tire explosions. Many citizens believe that reducing the pressure by deflating the tires can effectively prevent this problem. And the car consultant said that high tire pressure is easy to puncture, and low pressure is also easy to puncture. The correct method should be to adjust the tire pressure to the lower limit of the specified value. If the standard air pressure of car tires is 2.3 to 2.5 MPa, it can be adjusted to the lower limit of 2.3 MPa in summer.

In summer, you should also pay attention to the water temperature meter. In summer, when the engine is overheated and the outside temperature is too high, the vehicle enters a period of high incidence of spontaneous combustion. If the water temperature is too high, there will be some obvious symptoms, such as engine power drop, air conditioner failure, etc. Due to the high temperature, the engine may deflagrate, and the engine may have abnormal working noise. After these symptoms appear, the car consultant reminds the car owner not to get out of the car and open the front cover for inspection. The correct approach is to park the car aside and allow it to cool down naturally. Because the water temperature is too high, spontaneous combustion may have occurred. The moment the front cover is opened, air enters, which can easily burn people; in addition, the coolant that has been “boiled” may also burn people.

When the car uses air conditioning in summer, the external circulation should be used as much as possible. If the parking time is relatively long, more than 10 to 15 minutes, try not to cool off in the car; the air-conditioning filter is guaranteed to be replaced once a year. Do not rush to raise the window to the end within 2 minutes of the air conditioner functioning after getting in the car. Because the interior of the car and the air ducts of the air conditioner are made of plastic or rubber, which emits some harmful gases to the human body, it is necessary to use this 2 minutes to exhaust all the harmful gases in order to get all the windows. rising.
