CNC machining is a manufacturing technology that uses computer-controlled machine tools to cut, punch, drill, mill, turn, grind, etc., for the manufacture of various parts and components. CNC stands for computer numerical control, which is an automatic processing method that can accurately control the processing process through digital control instructions, so as to achieve high-precision and high-efficiency processing.
CNC machining has a wide range of applications. From aircraft parts, auto parts, ship parts, artificial bones, medical devices, to a variety of industrial machinery, and even entertainment equipment, CNC machining technology can be applied. Because the computer-controlled machining method has the characteristics of high efficiency, high precision, high quality and high stability, CNC machining is more and more widely used in the manufacturing industry.
The CNC machining process requires several steps. First, you need to design CAD drawings and convert the drawings into digital G code. The G code is then transferred to the CNC machine controller and the machining parameters are set. In the processing process, the machine tools will cut, boring, milling and other processing operations in accordance with the preset G code path, and finally produce accurate CNC machining parts and components.
In general, CNC machining is a very important manufacturing technology, which can help the manufacturing industry achieve large-scale production, efficient processing and high-quality production. With the continuous development of science and technology, CNC machining technology is also evolving, and CNC machining will be applied in more fields in the future
The new LGA4189-D96, LGA4189-D97, LGA4189-D82 and LGA4189-D83 are dedicated, customized solutions for Intel’s professional LGA4189 platform (Whitley), which makes these LGA 4189 cpu coolers an ideal fit for both Ice Lake-SP based 3rd generation Xeon Scalable CPUs (Platinum, Gold, Silver or Bronze) and W-3300 series Xeon processors for workstations (Ice Lake-64L). Whereas the large LGA4189-D97cpu cooler with two fans and LGA4189-D97 cpu cooler with one fan are an excellent choice for tower-style cases and thus lend themselves to use in high-performance quiet workstations, the smaller LGA4189-D96 fit 4U cases, which makes them perfect for more compact workstations as well as 4U class rack-mount servers that need to run as quietly as possible. While the LGA4189 cooler relies on a single 9225 PWM fan to achieve maximum performance, thanks to its large surface area, the LGA 4189 cpu cooler with two fans to ensure outstanding performance despite their smaller size and surface area.
In addition to the new LGA 4189 heatsinks, the NM-i4189 mounting kit allows LGA 3647 series coolers and TR4-SP3 series coolers to be installed on LGA4189.
All the new lga 4189 coolers are available as of today via Lori’s website: https://www.loricooler.com/lga-4189.html
Designed in China, Lori’s cpu coolers and fans are internationally renowned for their superb quietness, exceptional performance and thoroughgoing quality. Having received more than 6000 awards and recommendations from leading hardware websites and magazines, Lori’s fans and heatsinks are serving hundreds of thousands of satisfied customers around the globe.
LORI announced three LGA3647-4U-A31, LGA3647-4U-A32 and LGA3647-A35 4U quiet lga3647 cooler designed for the Intel LGA3647 platform as well as Intel scalable and Xlon melt core processors.
Applicable to Intel LGA3647 LGA3647-4U-A31, LGA3647-4U-A32 and LGA3647-4U-A36 4U quiet CPU coolers are based on sizes of 140 mm, 120 mm and 92 mm respectively. Covers everything from high-performance workstations to compact 4U servers. LORI's high-quality fans make them unusually quiet, ideal for use in noise-sensitive environments.
Lori has introduced three lga 3647 cpu coolers for the Intel LGA3647 platform. These new intel tower lga 3647coolers are dedicated solutions for the Intel LGA3647 platform and are ideal for scalable Xeon cpus based on skylake-SP and Xeon-Phi architectures. Its contact surface with the processor is 70×56 mm, more than double that of the standard model to ensure optimal cooling in these large processors. This custom design allows for optimal heat flow from the CPU to the aluminum cpu cooler of the heat pipe and heat sink.
Lori LGA3647-A35 4u cpu cooler is small and ideal for 4U rack-mounted servers that need to run quietly. The 12cm and 9cm models use a dual fan configuration to ensure excellent lga3647 cpu cooler performance despite a smaller size and surface area. They come with pre-coated thermal adhesive to ensure optimum joint line thickness and save installation time. Your SecuFirm2 mounting system includes two sets of brackets for supporting square and narrow LGA3647 sockets.
An air cooled cooling products, the effect of good or bad in addition to the fan to see the air volume, more is dependent on the design of the heat sink. A properly designed heat sink can make the computer run stably when it is not overclocked and not continuously full. It can be seen that the importance of the heat sink, and the heat sink heat dissipation effect and its production process is inseparable.
Nowadays, the production process of heat sink includes several technologies such as cutting, skiving, extrusion, stamping and die casting, etc., and more than ten kinds of specific heat sink manufacturing processes have been developed. In the following article, small make up will be for you one by one, let you in the choice of cooling products do know.
Cutting and aluminum extrusion
Strictly speaking, cutting is the abbreviation of a large class of production technology, such as high-speed cutting, laser cutting belong to this class, but they have a common point is the car, drilling, milling, grinding and other machine tools, in the heat heat sink fin forming process, in order to obtain some more special, fine shape, need to use cutting technology. Mainly used for plate forming (base, fin formation), heat sink grooves, special lines and so on.
Aluminum extrusion is will aluminum alloy ingot heating to 520 ~ 540 ℃, using mechanical pressure, the liquid aluminum through the extrusion die made of steel, in the mold exit to the cooling of liquid aluminum, rapid solidification, become a continuous parallel structure of heat sink in the early embryo, again to clip the early embryo, and he saw us common extruded heat sink.
Precision skiving and aluminum die casting
I have to say, this is a very landmark metal forming process. The definition of precision skiving is to cut a whole piece of metal profile according to the need, using a special planer with precise control to cut out the specified thickness of thin slices, and then bending up to an upright state, as a skived fin.The easier way to think about it is to take a piece of metal and cut it into the shape of a heat sink that we normally see.This method is most common in the pure copper heat sink.
Aluminum die casting is a widely used single aluminum alloy processing process. After melting the aluminum alloy ingot into a liquid state, it was filled into the model, and formed by die-casting machine in one time, and then after cooling and subsequent treatment, it was made into a single die casting heat sink.
Folding and soldering is the mainstream
The thin, dense heat sinks that we see are made in this way. In forming, the edges of the fins are left with a small specially designed bulge, which is fixed in a custom-made mold, and the bulge is bent and locked together to form an orderly arrangement of parallel fins. In combination with stamping, it is mainly used to manufacture parallel dense thin fins for reflow soldering or air duct design.
Soldering is a familiar way of metal processing. The most commonly used soldering method in heat sink processing is reflow welding, also known as reflow welding. At present, most of the heat pipe heat sink, heat pipe and fin connection is welding. Because the joint degree of welding directly affects the heat dissipation effect, the cost of welding is higher.
A variety of heat sink technologies.
Actually we in addition to the above these cooling process forms, as we can often see cold forging, bonded fin, and other heat sink technology, the process is more or less still appear in our computer cooling form, just for the cost or the cause of the heat dissipation effect is less and less, but these are still for heat sink has played a contribution to the development of technology.
