China PCBN Suppliers and Factory: High-Quality Polycrystalline Cubic Boron Nitride Sintered Products
PCBN
What is PCBN?
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
Typical Uses & Tooling
PCBN is typically used to machine brake discs, engineer blocks, engineer cylinder liners, brake drums, flywheels, valve seats and guides, gears, mold and dies parts etc. Suitable for making PCBN turning, and cutting tools.
Frequently Asked Questions (FAQ)
Q What is PCBN?
PCBN (Polycrystalline Cubic Boron Nitride) is a special class of super-hard material that is chemically inert and highly temperature resistant.
Q Why can't PCD diamond be used to machine ferrous alloys?
PCD diamond reacts chemically with ferrous alloys at high temperatures, which causes the tool to wear down rapidly during machining.
Q Which materials are suitable for PCBN machining?
PCBN is ideal for machining hard ferrous metal items such as gear steel, bearing steel, cast iron, and powder metallurgy materials.
Q What are the typical industrial components machined with PCBN?
PCBN is typically used to machine brake discs, engineer blocks, engineer 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 highly suitable for manufacturing high-performance turning and cutting tools designed for hard ferrous metal applications.
