    PCBN

    Material Characteristic Warning

    PCBN is a special class of super-hard material which is chemically inert and temperature resistant. It is well-known that PCD diamond cannot be used to machine ferrous alloys because it will chemically react and quickly wear.

    However, PCBN is well-suited for such ferrous-metal applications. PCBN is ideal for tools used to machine hard ferrous metal items such as: gear steel, bearing steel, cast iron, powder metallurgy material, etc.

    ⚙️
    Typical Machined Parts

    Brake discs, engine blocks, engine cylinder liners, brake drums, flywheels, valve seats and guides, gears, mold and dies parts, etc.

    🛠️
    Tool Applications

    Highly suitable and optimized for manufacturing premium PCBN turning and cutting tools.

    Frequently Asked Questions (FAQ)
    Q: What is PCBN and what are its key properties?

    PCBN (Polycrystalline Cubic Boron Nitride) is a special class of super-hard material. Its primary advantages are that it is chemically inert and highly temperature resistant.

    Q: Why can't PCD diamond tools be used to machine ferrous alloys?

    PCD diamond chemically reacts with ferrous alloys at high temperatures, which causes the tool to wear down and degrade very quickly.

    Q: Which ferrous metals are ideal for PCBN machining?

    PCBN is ideal for machining hard ferrous metal items, including gear steel, bearing steel, cast iron, and powder metallurgy materials.

    Q: What specific components are typically machined using PCBN tools?

    It is commonly used to machine automotive and industrial components such as brake discs, engine blocks, engine cylinder liners, brake drums, flywheels, valve seats and guides, gears, and mold/die parts.

    Q: What types of tools are made from PCBN?

    PCBN is widely used and highly suitable for manufacturing high-precision turning and cutting tools.
