An advanced manufacturing technology that combines high efficiency, high quality, and low consumption is called CNC high-speed cutting of aluminum alloy cavity shell. High-speed cutting has solved the problems of easy deformation and poor surface quality of parts that have been caused by conventional cutting. These issues have been a problem because conventional cutting is done at slower speeds. In order to carry out CNC high-speed milling on aluminum online cnc machining service alloy cavity shell, high-speed machining technology and operation method are adopted. This is done by optimizing the high-speed cutting tool path and selecting cutting parameters, with the goal of achieving the purpose of improving processing efficiency and ensuring processing quality.
Cutting at high speeds with a CNC machine enables the use of a larger feed rate, custom cnc milling which is anywhere from five to ten times higher than the rate used in conventional cutting. As a result, the rate of material removal per unit of time can be increased by three to six times, and the amount of time required for processing can be greatly reduced. It is especially useful for the CNC machining of cavity parts made of aluminum alloys. Parts that need a significant amount of metal to be removed can be processed using it. When compared to conventional cutting, high-speed cutting can reduce the cutting force by at least 30 percent. This can help reduce processing deformation for parts that have poor rigidity, which means that cutting aluminum alloy cavity shells is no longer an issue.
The high-speed cutting process is incredibly quick, more than 95% of the heat generated during cutting is minimal, and the aluminum alloy cavity shell parts do not warp or expand as a result of the temperature increase. When processing components that are prone to thermal deformation, high-speed cutting is an especially useful technique to have. Cutting at high speeds is of particular significance when it comes to the processing of metals that have a low melting point and are prone to oxidation.
Because the excitation frequency of tool cutting is far removed from the forced vibration of the process system during high-speed rotation, which ensures a better processing state. Because the cutting force is too low, the influence of the cutting heat is also low. As a result, the amount of deformation that occurs in both the tool and the workpiece is minimal, which ensures that the dimensions are maintained with high precision. In addition, there is less friction between the tool and the workpiece, the cutting damage layer is reduced, and there is less residual stress, all of which contribute to the high level of precision that is achieved. Processing benefits greatly from a smooth surface. The use of conventional processing methods does not provide a guarantee that the finished parts will not be deformed, and it is difficult to significantly improve processing efficiency using these methods. When the cavity shells are made of an aluminum alloy, it is even more difficult to guarantee the product's quality during processing.
When they are processed, cavity shells made of aluminum alloy frequently experience problems with deformation. The conventional processing method of large cutting amount, slow tool feed cutting method causes a large amount of cutting heat on the surface of the part to be unable to be taken away in time, and it remains on the surface of the part, causing parts to be easily deformed. This is because the cutting method causes a large amount of cutting heat on the surface of the part to be unable to be taken away in time. The overall rigidity of the aluminum alloy cavity shell is also low, and it is also very suitable for selecting small-diameter tools, high-speed machining processes with high speed, small knife capacity, and large feed rate. Additionally, it is very suitable for cnc milling online high-speed machining processes with small knife capacity. The surface of the part will remain at room temperature even after high-speed machining because the chips and cutting fluid will remove 95% of the heat that is generated during the process. In addition, the cutting force and cutting power generated by high-speed machining are very low. This ensures that the tool will not squeeze the surface of the part, which in turn reduces the amount of deformation that the part experiences, which in turn effectively ensures that the processing quality of the part is maintained.
When it comes to the choice of processing tools and feed speed, the cutting speed of solid carbide end mills used for the machining of aluminum alloy parts can generally reach 1000m/min, which means that the choice of cutting parameters for the D8 end mills that are used is primarily limited by the machine tool. Spindle speed and feed speed, the spindle speed is calculated to be 18000 revolutions per minute, the feed speed for rough machining is determined to be 6000 millimeters per minute, and the feed speed for finishing machining is calculated to be 2000, taking into consideration the rigidity of the cavity shell workpiece and the surface quality of the part. If the performance of the machine tool is satisfactory, it will be possible to increase both the cutting speed and the feed speed to an appropriate level.
Processing technologies that are more commonly used are not suitable for the CNC processing of cavity shells made of aluminum alloys. Because the processing technology used for these kinds of parts places a restriction on the amount of depth that can be cut into a layer, the utilization of CNC high-speed processing is the most effective method for maximizing the efficiency of the processing and ensuring the quality of the parts produced. The appearance of electronic products is currently trending toward becoming thinner and lighter, reflecting the current trend in product development that sees electronic products becoming increasingly diverse. As a result, electronic radiators made of aluminum alloy are being challenged to fit into increasingly constrained spaces inside of electronic products. Increasing the capacity for heat dissipation has been a problem that has always been present in electronic products, and it cannot be ignored. The primary concern of the industry at this point is determining how to maximize heat dissipation in spaces that are otherwise constrained.
Because of this, the heat sink has a low mass, excellent thermal conductivity, and excellent plasticity. It is only through relying on the limited size that it is possible to maximize the heat custom cnc milling dissipation performance, which is the only way that it can truly protect the heat dissipation of electronic products. At the moment, the vast majority of radiators are constructed from aluminum alloy. Despite the fact that the heat dissipation performance is not quite as good as copper's, the heat dissipation coefficient is able to fully satisfy the heat dissipation requirements of electronic products. In addition, the fact that it is not particularly heavy, that it can be worked with in a simple manner, that it possesses a lovely appearance, and that its price is not particularly high makes it particularly suitable for application.
After undergoing CNC processing, the product is then subjected to surface treatment processes such as sandblasting, wire drawing, and laser. These processes make the surface of the radiator cleaner and smoother, and they bolster the strength of the decoration. The goals of these processes are to make the radiator more aesthetically pleasing in appearance, to extend its useful life, and to improve its heat dissipation performance. The overall wear resistance, corrosion resistance, and heat resistance of the radiator can be improved by adding an electroplating layer, oxide layer, and special material paint on the surface. This allows the performance and durability of the radiator to be improved. In addition to electroplating, anodic oxidation, and baking paint processes. has experienced an increase in overall quality. For CNC processing to customize aluminum alloy electronic radiators, high-quality materials are used today due to the development of light and thin electronic products. It is light and ultra-thin, with a delicate appearance, and it has a good ability to dissipate heat in order to fully meet the needs of the customer.
