Introduction to CNC milling cutter products

Please explain several commonly used types of milling cutters in their application scenarios.
（1） Single edge milling cutter
This cutting tool has high processing efficiency and uses high-quality hard alloy as the cutting body. Generally, it adopts sharp edge grinding technology and high capacity chip removal, which makes the tool non stick chips, low heat generation, and high smoothness in high-speed cutting. It is widely used in industries such as handicrafts, electronics, advertising, decoration, and wood processing, suitable for factory batch processing and high demand products.
（2） Two edge end mills and four edge end mills
This type of tool generally adopts an overall alloy structure, which is characterized by strong stability. The tool can work stably on the machining surface, effectively ensuring the machining quality. Suitable for a wide range of materials, such as carbon steel, mold steel, alloy steel, tool steel, stainless steel, titanium alloy, cast iron, suitable for general mold and mechanical parts processing.
（3） Thread milling cutter
With the development of CNC machine tools in China, thread milling cutters are increasingly recognized by people. Their excellent processing performance has become a powerful tool for reducing thread processing costs, improving efficiency, and solving thread processing problems. Due to the manufacturing material of the thread milling cutter being hard alloy, the processing speed can reach 80-200m/min, while the processing speed of the high-speed steel wire cone is only 10-30m/min. Therefore, the thread milling cutter is suitable for high-speed cutting, and the surface finish of the processed thread is also greatly improved. The thread machining of high hardness materials and high-temperature alloy materials, such as titanium alloy and nickel based alloy, has always been a relatively difficult problem, mainly because high-speed steel wire taps have a shorter tool life when machining the threads of these materials. However, using a hard alloy thread milling cutter for machining hard material threads is an ideal solution, with a machinability hardness of HRC58-62. For thread processing of high-temperature alloy materials, thread milling cutters also exhibit excellent machining performance and unexpected long lifespan. For threaded holes with the same pitch and different diameters, using a tap machining requires multiple cutting tools to complete. However, if using a thread milling cutter for machining, using one cutting tool is sufficient. After the tap is worn or the processed thread size is less than the tolerance, it cannot be used anymore and can only be scrapped; When the thread milling cutter is worn and the size of the processed thread hole is less than the tolerance, necessary tool radius compensation adjustments can be made through the CNC system to continue processing qualified threads. Similarly, in order to obtain high-precision threaded holes, using a thread milling cutter to adjust the tool radius is much easier than producing high-precision taps. For small diameter thread processing, especially for high hardness and high-temperature materials, the tap may sometimes break, block the threaded hole, and even cause parts to be scrapped; Using a thread milling cutter, due to the smaller diameter of the tool compared to the processed hole, even if it is broken, it will not block the threaded hole, making it very easy to remove and will not cause parts to be scrapped; By using thread milling, the cutting force of the cutting tool is significantly reduced compared to the tap, which is particularly important for machining large diameter threads. This solves the problem of the machine tool being overloaded and unable to drive the tap for normal machining.
Thread milling cutter, as a tool for machining threads using CNC machine tools, has become a widely used practical tool type.
