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

Application of DC cooling fan in various fields

Application of DC cooling fan in various fields

 Cooling fans are generally used in printers, fax machines, banner machines, medical equipment, automotive electronics, power equipment, electric vehicle chargers, communication/communication cabinets, frequency converters, transformers, industrial control equipment, stage lighting (light source cooling), new energy ( Cooling fans are required for equipment such as batteries into cabinets), engine cooling, instruments and meters.

  DC cooling fans have a wide range of applications, but cooling fans are generally installed inside the machine. Now, most devices will generate heat after running, and they need cooling fans to dissipate heat. The application of cooling fans in various fields is described in detail below.

Cooling fans are generally used in printers, fax machines, banner machines, medical equipment, automotive electronics, power equipment, electric vehicle chargers, communication/communication cabinets, frequency converters, transformers, industrial control equipment, stage lighting (light source cooling), new energy ( Cooling fans are required for equipment such as batteries into cabinets), engine cooling, instruments and meters.

The following is an example of the application of automobile cooling fans in automobiles

The replacement of automobiles clearly marks the changes of this era, and each generation of changes has higher and higher requirements for heat dissipation. From the initial heat dissipation, to the need to reduce noise while satisfying heat dissipation, and then to develop, not only reduce noise and heat dissipation, but also need to be able to control heat dissipation in real time, that is, to support PWM intelligence fan speed regulation cooling fans.

 

·         During the operation of the car, heat is continuously generated, and the components around the combustion chamber (cylinder liners, cylinder heads, valves, etc.) must be properly cooled. The automobile cooling system is composed of radiator, thermostat, water pump, Communications,cylinder water channel, cylinder head water channel, fan, etc. The radiator is responsible for th,e cooling of circulating water. Its water pipes and heat sinks are mostly made of aluminum materials. The aluminum water pipes are made of flat shape, and the heat sinks are corrugated. The heat dissipation performance should be taken into account. The installation direction is perpendicular to the air activity direction. It is possible to achieve smaller wind resistance and higher cooling efficiency.


The coolant flows inside the radiator core and the air passes outside the radiator core. The hot coolant is cooled by dissipating heat to the air, and the cold air is warmed by receiving heat from the coolant, so the radiator is a heat exchanger. The cooling fan is installed in the radiator to blow away the heat in time to achieve the whole cooling effect.
