High-Quality PCBN (Polycrystalline Cubic Boron Nitride) from China Suppliers and Factory
PCBN
Material Performance
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.
Ferrous-Metal Applications
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. PCBN is typically used to machine brake discs, engineer blocks, engineer cylinder liners, brake drums, flywheels, walue seats and guides, gears, mold and dies parts etc. Suitable for making PCBN turning, and cutting tools.
Frequently Asked Questions
What is PCBN and what are its key properties?
PCBN (Polycrystalline Cubic Boron Nitride) is a class of super-hard materials characterized by high chemical inertness and exceptional temperature resistance, making it highly durable under extreme machining conditions.
Why is PCD diamond unsuitable for machining ferrous alloys?
PCD diamond reacts chemically with the iron in ferrous alloys at high temperatures, which leads to rapid tool wear and degradation during the machining process.
Which materials are best suited for PCBN machining?
PCBN is ideal for machining hard ferrous metal items, including gear steel, bearing steel, cast iron, and powder metallurgy materials.
What are the typical components manufactured using PCBN?
PCBN is commonly used to machine critical industrial and automotive components like brake discs, engine blocks, cylinder liners, brake drums, flywheels, valve seats and guides, gears, and mold/die parts.
Can PCBN be used to create specific cutting tools?
Yes, PCBN is highly suitable for making high-efficiency turning inserts and cutting tools designed for high-precision operations on hard ferrous metals.
