What are the advantages of CNC machining of radiator parts?

For friends who have been in contact with the radiator component industry, they often see or hear "CNC machining", but too much exposure does not necessarily mean that many people understand. In fact, many questions are still about CNC machining. What are the advantages? Let's take a closer look. CNC machining is an index-controlled machine tool machining, which is a method of using digital information to control the machining process. Traditional mechanical processing is done manually by machine tools. During processing, the mechanical cutter is shaken to cut metal, and the accuracy is measured with calipers and other tools. However, traditional artificial intelligence processing is far from being able to meet the needs of production development. Therefore, the emergence of CNC machining provides the possibility for the standardization, precision and efficiency of mechanical product processing. The CNC machining process in the radiator component industry also shines. The

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

Investment Casting Materials and Manufacturing Process

Mold material The performance of the molding material should not only ensure the convenient production of investment molds with accurate dimensions and high surface finish, good strength and light weight, but also create conditions for the manufacture of mold shells and good castings. Molding materials are generally formulated with waxes, natural resins and plastics (synthetic resins). All mold materials mainly prepared with wax materials are called wax-based mold materials, and their melting point is low, 60~70 ° C; all mold materials mainly prepared with natural resins are called resin-based mold materials, with a slightly higher melting point, about 70 °C. ~120℃. invest-casting.com   Precision Investment Castings China prototype company service include :  High Quality Investment Casting Parts Custom , Lost Wax Investment Casting Sand Casting , Lost Foam Casting , Gravity Casting , Die Casting , Graphite Casting , Casting Moldsmanufacturers .

Selection of LED light drive power

Selection of LED light drive power

The choice of LED lamp power supply is mainly considered from the output voltage, output current, and corresponding power wattage of the power supply. LED power supply generally has two types of constant current source output and constant voltage source output. First, for the LED power supply output by constant current source, we mainly consider its output voltage. For LED power drivers that output the same current, its output voltage It is also different, so when choosing a constant current LED power supply, it should be consistent with the working voltage of the LED lamp. For example, for a constant current LED power supply with a rated current of 200 mA to 300 mA, its output voltage is between 9V and 13V. The range between 10V and 25V, the range between 24V and 42V, the range between 45V and 63V, etc., so we choose this power supply to consider its output voltage range.

 

   Similarly, for the constant voltage source LED power driver, under the same output voltage, its output current is also different, so when we choose LED power supply, we need to consider its output voltage or current according to different types of LED power supply. . In addition, the power range of the LED power supply should also be considered. If the power range is selected incorrectly, the LED lamp beads will be burned, or the LED lamp will flicker.

 

   For simple LED lamps, it is often used to reduce the voltage through a simple RC resistance-capacitor step-down link, and then arrange it through a diode and add a suitable current-limiting resistor to drive about a dozen high-brightness LED lamp beads. Yes, the lamp beads here can be connected in parallel or in series, but the current limiting resistor must be selected well. For example, the mini LED desk lamp I made before is a power supply formed by this method. I used 12 LED lamp beads in parallel, and used a 2.4 ohm two-watt resistor as the current limiting resistor, and the effect was very good.

 

The LED light has high brightness and saves electricity. Now in order to make LED lights more humane, we can also choose LED power supply with dimming function, such as LED dimming power supply using thyristor, which has high adjustment accuracy and efficiency. If you need to install in a small space, you can choose this LED power supply with dimming function.

 

Some LED power supplies with dimming function are made of MOS tubes, which are also called MOSFET dimmers. It can not only control the on and off of LED lights, but also control the LED lights. Like the LED dimmable power supply made of silicon, the phenomenon of invisible lighting occurs. This kind of LED dimmable power supply can be selected for a single LED lighting lamp or occasions with a small load.
