ما هي أنواع مواد الشغل الأنسب للتصنيع باستخدام إدخالات CBN?
إدراج نيتريد البورون المكعب (CBN) 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, إدراج CBN 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 إدراج CBN أدخل:
الفولاذ المقوى: إدراج CBN 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.
الحديد الزهر: إدراج CBN 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.
سبائك درجة حرارة عالية: إدراج CBN 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 إدراج CBN a preferred choice for cutting them efficiently.
المواد الصلبة والهشة: إدراج CBN 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: إدراج CBN 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 إدراج CBN excel in this regard.
المواد الكاشطة: إدراج CBN 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.
الصلب المقوى: إدراج CBN 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 إدراج CBN تقدم أداء ممتازا في تصنيع هذه المواد ، وظروف القطع المناسبة ، وإعداد الأداة ، واستراتيجيات التبريد ضرورية لزيادة كفاءتها وعمر الأداة. بالإضافة إلى ذلك ، يجب اختيار الدرجة والهندسة المحددة لإدراج CBN بناء على المواد التي يتم تشكيلها ومعلمات عملية المعالجة.
