1. Properties and Advantages of CBN Inserts
CBN (Cubic Boron Nitride) inserts are suitable for turning high-hardness materials such as hardened steel and cast iron. CBN is second only to diamond in hardness and can maintain its hardness even at high temperatures, making it ideal for high-speed and continuous turning. Furthermore, CBN inserts have high wear resistance, which extends tool life and significantly improves turning stability and quality.
2. Properties and Advantages of PCD Inserts
PCD (Polycrystalline Diamond) inserts are suitable for turning non-ferrous and non-metallic materials. PCD has high hardness and a low coefficient of friction, making it ideal for applications requiring a polished surface. For turning materials such as aluminum alloys and carbon fiber (CFRP), PCD inserts provide excellent surface finish and enable high-speed turning.
3. Applications and Examples of Each Insert Type
CBN inserts are suitable for turning high-hardness materials such as cast iron, hardened steel, and sintered alloys. Meanwhile, PCD inserts are suitable for turning non-ferrous materials such as aluminum alloys, copper alloys, and CFRP. Selecting the appropriate insert will significantly improve turning efficiency and quality.
4. Key Considerations for Selecting Inserts to Enhance Turning Performance
Selecting the appropriate insert is crucial for enhancing turning performance. Considerations should include the material to be turned, machining conditions, and desired surface finish. For high-hardness materials, CBN inserts should be chosen, and for non-ferrous materials, PCD inserts should be selected. This will help extend tool life and reduce turning costs. Furthermore, selecting the appropriate insert size, geometry, and chip breaker are also important factors for increasing efficiency.
5. Reasons to Recommend Mitsubishi Materials' CBN and PCD Inserts
