Carbide APMT Insert tools, made from a combination of carbon and tungsten, are known for their hardness and durability. They are widely used in machining applications due to their resistance to high temperatures and wear. However, like any tool, carbide tools also have limitations that users need to be aware of. Some of the limitations of carbide tools include:
1. Brittle nature: While carbide tools are extremely hard, they are also brittle. This means that they are prone to chipping or breaking if subjected to sudden shocks or impacts. Care must be taken to avoid dropping or mishandling carbide tools to prevent damage.
2. Limited heat resistance: While carbide tools have good resistance to high temperatures, they have a lower heat resistance compared to some other cutting tool materials like ceramics. This can lead to rapid wear and deterioration of the cutting edge when machining materials that generate a lot of heat, such as high-strength steels or superalloys.
3. Not suitable for all materials: Carbide tools are best suited for machining hard materials like steel, cast iron, and stainless steel. They may not perform as well when used on softer materials like aluminum or copper, as the cutting edges may wear out quickly.
4. High cost: Carbide tools are more expensive than some other cutting tool materials, such as high-speed steel. This can make them less cost-effective for some users, especially those with low-volume machining requirements.
5. Limited edge sharpness: Carbide tool inserts have a finite number of cutting edges, known as inserts. Once all the edges have been used up, the insert must be replaced. This can be costly and time-consuming, especially in high-volume machining operations.
In conclusion, while carbide tools have many advantages, they also have CNMG Insert limitations that users need to consider when selecting cutting tools for their applications. By understanding these limitations, users can make informed decisions on when and how to use carbide tools effectively.
