Eagle’s PCD / PCBN

PCD and PCBN blanks and compacts work great in a broad range of milling, turning and machining applications.

PCD & PCBN blanks can dramatically reduce your machining costs by:
Consistently providing the hardest cutting edge available
Proving more wear-resistant than other carbide-based materials
Improving overall efficiency and quality by reducing tedious setup times and the need to frequently change tooling

Features of PCD/PCBN Cutters

High hardness can be 8-12 times higher than carbide tools.
Life will be 50 – 200 times longer than carbide tools
High thermal conductivity – PCD/PCBN cutters have a fast heat transfer rate
Low friction coefficient  – PCD/PCBN cutters can decrease the cutting force
Thermal expansion coefficient of PCD/PCBN only 1/5 of carbide tools, so they have less thermal deformation and high machining precision.

Differences in PCD & PCBN Cutters

PCD:Polycrystalline Diamond Cutters
Used for nonferrous metal and non-metallic material.
They have good cutting performance and effect for copper, aluminum, manganese, gold, silver, magnesium, titanium.
Used for machining wear-resistant non-metallic material, such as wood, ceramic, graphite, nylon, plastic, etc.
PCBN- Polycrystalline Cubic Boron Nitride Cutters
Used for machining ferrous metal
Especially suitable for machining kinds of hardened steel, pearlite green cast iron, chilled cast-iron, superalloy and other materials that not lower than 50HRC.

What are PCD Pucks?

Polycrystalline Diamond (PCD) is an advanced material known for its exceptional hardness and wear resistance, making it a preferred choice in cutting tools for machining non-ferrous metals, composites, and abrasive materials. Our PCD pucks stand out with superior durability, ensuring prolonged tool life and reduced downtime. Precision-engineered to perfection, our PCD pucks deliver unrivaled performance in demanding applications such as aerospace, automotive, and woodworking. With high thermal conductivity and excellent chemical stability, our PCD solutions provide optimal heat dissipation and maintain sharp cutting edges, resulting in impeccable surface finishes and enhanced productivity. Elevate your machining capabilities with our cutting-edge PCD pucks, setting new standards in efficiency and reliability.

PCD-tipped tools are ideal for cutting abrasive and wear-resistant materials, including:
Aluminum & Aluminum Composite Material (ACM)
Carbon Fiber
Composite Panels
Custom Composite Materials

What are PCBN Pucks?

Polycrystalline Cubic Boron Nitride (PCBN) is an essential material used in high performance cutting tool manufacturing , renowned for its exceptional hardness and heat resistance. Our PCBN pucks are meticulously crafted to meet the demands of high-speed machining applications, particularly in ferrous metal processing like hardened steels and cast irons. Featuring superior wear resistance and thermal stability, our PCBN pucks ensure prolonged tool life and consistent performance under extreme conditions. Precision-engineered with cutting-edge technology, our PCBN solutions empower industries such as automotive, aerospace, and gear manufacturing to achieve unparalleled efficiency and accuracy. Choose our PCBN pucks for a transformative edge in precision machining and reliable, long-lasting tooling solutions.

Both PCD and PCBN show excellent wear characteristics and offer unparalleled performance in terms of thermal hardiness, toughness and stability over the life of the toughest projects.
