PCBN Diamond Blanks

Product Overview

Polycrystalline cubic boron nitride (PCBN) composite blanks are made from high-quality cubic boron nitride (CBN) micron powder combined with a special ceramic bonding system. Through careful design and processing, these blanks offer outstanding wear resistance, thermal stability, and chemical stability. They are widely used in high-performance cutting tools, especially for machining hard and complex materials, offering superior machining accuracy and tool life.

Features

• Exceptional Wear Resistance: High-purity cubic boron nitride gives PCBN excellent wear resistance, making it ideal for demanding cutting environments.
• Thermal and Chemical Stability: PCBN maintains excellent thermal stability under high temperatures, suitable for high-temperature machining, and offers strong chemical stability.
• High Impact Resistance: PCBN materials have strong impact resistance, ensuring stable performance even under high-load conditions.
• High CBN Content: With a high content of cubic boron nitride, PCBN is particularly effective for machining hard materials like cast iron.
• Uniform Microstructure: The precise microstructure design ensures consistent performance during cutting, extending tool life.

Applications

• Cast Iron Machining: PCBN is particularly effective for machining cast iron, ductile iron, and other hard materials, especially in high-speed machining of gray cast iron.
• Tool Manufacturing: Widely used in manufacturing various cutting tools, including components with high wear resistance requirements, such as engine parts and cylinder heads.
• Powder Metallurgy and Metal Machining: Suitable for precision machining of hard materials such as powder metallurgy, hardened steels, tool steels, mold steels, and bearing steels.
• Complex Material Machining: Can be used to machine high-hardness alloys, cobalt-nickel-based alloys, and other special materials, offering high toughness and extended tool life.
