CBN 인서트를 사용한 가공에 가장 적합한 공작물 소재 유형?
입방 질화붕소(CBN) 인서트 are known for their excellent performance in machining hard materials. CBN is a synthetic material that has hardness and abrasion resistance second only to diamond. Therefore, CBN 인서트 are best suited for machining materials that are challenging to cut with traditional carbide inserts due to their hardness and abrasiveness. Some of the materials that are well-suited for machining with CBN 인서트 포함하다:
경화 강: CBN 인서트 are commonly used for machining hardened steels with a hardness level of 45 HRC (Rockwell C) and higher. This includes tool steels, die steels, and other high-strength steel alloys. They can provide high material removal rates and extended tool life in these applications.
주철: CBN 인서트 are effective for machining cast iron materials, including gray cast iron and ductile iron. They offer superior wear resistance and can maintain consistent cutting performance in cast iron applications.
고온 합금: CBN 인서트 are suitable for machining high-temperature alloys, such as Inconel, Hastelloy, and other nickel-based and heat-resistant alloys. These materials are known for their high hardness and toughness, making CBN 인서트 a preferred choice for cutting them efficiently.
단단하고 부서지기 쉬운 재료: CBN 인서트 are ideal for machining hard and brittle materials, including ceramics and sintered carbides. They can provide precise machining with minimal tool wear in these applications.
Powder Metallurgy Components: CBN 인서트 are commonly used for machining components made from powder metallurgy processes, including hardmetal (cemented carbide) parts. These materials can be challenging to machine with traditional tooling due to their high hardness, but CBN 인서트 excel in this regard.
Superabrasive 물자: CBN 인서트 are suitable for machining materials that are considered superabrasive, such as composite materials with abrasive additives. CBN's wear resistance makes it an excellent choice for cutting through these types of materials.
강하게 한 방위 강철: CBN 인서트 are often employed in the manufacturing of precision bearings, where hard materials like bearing steel require machining to tight tolerances.
It's important to note that while CBN 인서트 이러한 재료를 가공할 때 탁월한 성능을 제공하며, 적절한 절삭 조건, 공구 설정 및 절삭유 전략은 효율성과 공구 수명을 극대화하는 데 필수적입니다. 또한 CBN 인서트의 특정 재종과 형상은 가공되는 재료와 가공 공정 매개변수에 따라 선택해야 합니다.
