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.

Eagle’s PCD

PCD is a composite of diamond particles that are sintered under extreme pressure and temperatures to create a variety of products that are particularly suitable for cutting tools of non-ferrous metals and non-metallic materials, including the wear parts of various equipment.

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
Fiberglass

Eagle’s PCBN

PCBN products got through a very similar manufacturing process, but CBN particles are used in place of diamond, making PCBN ideal for ferrous materials – typically a form of steel – used in cutting, drilling and milling tools.

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.
