What Types of Materials are Suitable for Milling Inserts
Milling inserts are an important component of milling operations, as they not only increase the accuracy and efficiency of the machining process, but also help to reduce wear and tear on the cutting tools. As such, selecting the right material for milling inserts is critical to ensure that they can withstand the rigors of the machining process. Common materials used for milling inserts include carbide, ceramic, and polycrystalline diamond (PCD).
Carbide is a popular choice for milling inserts due to its hardness and wear resistance. It can be used for a wide range of materials, from aluminum to cast iron, and is available in a variety of grades and sizes. The downside to carbide is that it is relatively brittle and can be prone to chipping and breaking.
Ceramic is another commonly used material for milling inserts. It is harder than carbide, but less brittle, making it an ideal choice for high-speed machining. Ceramic is also corrosion resistant and can withstand temperatures up to 1400°C, making it suitable for a wide range of applications. The downside to this material is that it is relatively expensive.
Lastly, PCD is a synthetic material that is extremely hard and wear resistant. It is ideal for machining difficult-to-cut materials and can withstand temperatures up to 1500°C. The downside to PCD is that it is expensive and difficult to machine, so it should only be used when other materials are not suitable.
In conclusion, there are a variety of materials that can be used for milling inserts, including carbide, ceramic, and PCD. Each material has its own advantages and disadvantages, so it is important to consider the application and select the right material for the job.
