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

How to solve the poor heat dissipation of automobile engines and air conditioning systems

Car engine and air-conditioning system have poor heat dissipation, resulting in excessively high water temperature. The following fault phenomena and solutions will occur: 1. When the traffic is not smooth-traffic jam or long idling, the engine water temperature gauge shows too high, and the electronic fan works in high-speed gear. If it is too long, the engine noise will increase. If the temperature is too high, the malfunction* will be obvious when the air conditioner is turned on.

Solution: After the car is hot, check the water return of the return pipe at the upper end of the antifreeze storage tank. If the return water is not smooth or blocked, the water temperature will be too high.

Reminder: Do not blindly disassemble and replace parts during maintenance.

2. When the air temperature is too high and the air conditioner is turned on, the idling speed is unstable and the speed fluctuates too much, the acceleration is weak, and the engine makes abnormal noise.

Solution: Check whether there is too much dust between the condenser and the water tank, and clean it thoroughly with high-pressure air to ensure that the water tank and the condenser have good heat dissipation performance.

Reminder: usually pay attention to wipe the dust between the condenser and the water tank.

3. After a hot car is turned off for more than ten minutes, it is not easy to start the car; when a hot car is running, it will sometimes turn off automatically.

Solution: When the car is hot, check the temperature difference between the upper and lower water pipes of the water tank. If the temperature difference is too large, you need to check the opening of the thermostat and whether the water pump has rotation speed failure.

Reminder: The temperature difference between the upper and lower water pipes of the water tank should not be too large.

4. When the car is cold, the air-conditioning refrigeration temperature is very cool, and the cooling effect of the air-conditioning is not obvious when the car is hot; and there is a large resonance hum in the air-conditioning system.

Solution: Due to the irregular addition and replacement of antifreeze, the engine water channel and water tank will be blocked in advance and the water temperature will be high. The antifreeze is replaced once every two years, and original parts must be used when replacing and adding.

Reminder: After adding water to the engine cooling system, or the concentration of the added antifreeze exceeds 60%, it will cause the water temperature to be too high.
