Features:
Polycrystalline diamond (PCD) and cubic boron nitride (CBN) Inserts
for Advanced Cutting
Polycrystalline diamond (PCD) and cubic boron nitride (CBN) inserts
are highly advanced cutting tools that can be used for machining
processes due to their unique material properties. The following is
a summary of the key features and applications of PCD and CBN
inserts.
Features of PCD Inserts:
- Material Hardness: PCD inserts are extremely hard and are ideal for cutting
non-ferrous materials.
- Wear Resistance: PCD's hardness contributes to excellent wear resistance, making it
appropriate for prolonged machining tasks with minimal tool
degradation.
- Thermal Conductivity: PCD has excellent thermal conductivity, aiding in heat dissipation
during machining, which helps maintain tool integrity and reduces
the risk of thermal damage.
- Surface Finish: PCD tools provide superior surface finish and dimensional
accuracy, essential for high-precision applications.
- Chemical Stability: PCD is resistant to chemical reactions and may be suitable for
machining materials that may be abrasive or reactive.
- Low Friction: Their low friction coefficient reduces the cutting forces needed,
which allows for high-speed machining.
- Versatility: PCD inserts can perform various operations like turning, milling,
and drilling, primarily on non-ferrous materials like aluminum,
composites, and plastics.
Features of CBN Inserts:
- High Hardness: CBN is the second hardest material after diamond, making CBN
inserts ideal for cutting hard ferrous materials, including
hardened steels.
- Wear Resistance: CBN exhibits excellent wear resistance, especially for high-speed
machining environments, just like PCD.
- Thermal Stability: CBN can withstand high temperatures without significant
degradation, which is advantageous for cutting applications like
those that generate high heat.
- Chemical Stability: CBN is chemically stable at high temperatures, which is crucial
for machining materials that may generate reactive conditions.
- Edge Strength: CBN inserts maintain edge integrity better than traditional
carbide tools in cutting hard materials, thus reducing the risk of
chipping or breaking.
- Cutting Efficiency: CBN tools allow for efficient chip removal and reduction in
machining forces, which may enhance productivity.
Applications:
PCD and CBN inserts have specific applications. PCD is better for
non-ferrous materials like aluminum, composites, and plastics. In
comparison, CBN excels regarding ferrous materials, which are
hardened steels. CBN inserts are thus ideal for machining hardened
steels and iron-based materials, making them a common choice in
automotive and aerospace applications.
Comparison:
Regarding cost, PCD tends to be more expensive due to the diamond
content and manufacturing process, making CBN somewhat less costly.
However, both inserts offer prolonged tool life compared to
conventional carbide due to their hardness and wear resistance.
Conclusion:
PCD and CBN inserts are irreplaceable components in the modern
machining industry, providing precision, efficiency, and superior
performance in their respective applications. Understanding the
unique features and benefits of each type can enable manufacturers
to choose the right inserts for their machining needs.

The Technical Parameters of PCD and CBN Inserts
The technical parameters of PCD (Polycrystalline Diamond) and CBN
(Cubic Boron Nitride) inserts can vary based on their specific
application, geometry, coating, and manufacturer. However, some
common technical parameters are often evaluated when considering
these inserts. Here’s an overview of typically relevant parameters
for both PCD and CBN inserts:
PCD Insert Technical Parameters
- Material Composition: PCD inserts are made from diamond particles bonded with a metal
matrix, which may vary depending on the specific application.
- Hardness: Vickers Hardness is typically greater than 6000 HV, depending on
the composition and manufacturing process.
- Thickness: Common thickness ranges from 0.5 mm to 10 mm, depending on the
application.
- Grain Size: Average grain size can vary from 1 μm to several microns,
influencing wear resistance and toughness.
- Thermal Conductivity: Thermal conductivity is around 700-900 W/m·K, making it effective
for heat dissipation.
- Coating: Common coatings include PVD or CVD coatings may be applied to
enhance performance, depending on the material being machined.
- Edge Preparation: Sharpened or honed edges can enhance cutting performance in
specific applications.
- Geometry: Various shapes are available such as round, square, triangular,
and more, each optimized for particular cutting applications.
- Chip Breaker Design: Various chip breaker configurations can enhance chip control and
improve cutting efficiency.
CBN Insert Technical Parameters
- Material Composition: CBN inserts are typically made of cubic boron nitride in a solid
form, sometimes in combination with a binder such as cobalt or
ceramic.
- Hardness: Vickers Hardness is typically 4500 - 5000 HV, providing excellent
wear resistance for hard materials.
- Thickness: Common thickness is similar to PCD inserts, ranging from
approximately 0.5 mm to 8 mm or more based on specific
applications.
- Thermal Stability: CBN can withstand temperatures up to about 1000°C (1832°F) without
significant degradation.
- Coating: Common coatings often include TiN, TiC, or Al2O3 coatings, which
can enhance wear resistance depending on the application.
- Edge Preparation: Suitable edge preparations are used to optimize performance based
on the specific material and machining operation.
- Geometry: Various shapes are also available like square, round, and
octagonal, facilitating different types of machining operations.
- Chip Breaker Design: Various chip breaker geometries are used for controlling chip flow
and optimizing cutting conditions.
- Grain Size: Typically varies according to the manufacturing process and
intended use; finer grain sizes offer better edge stability.
General Considerations for Both Inserts
- Insert Size: Standard insert sizes follow the ISO metric system (e.g., ISO ISO
8885:1993) and ANSI standard (e.g., ANSI B212).
- Flank Wear Resistance: Measurement of flank wear resistance is critical for assessing
tool life. This is sometimes measured in microns (µm) after
standard machining tests.
- Cutting Edge Strength: The cutting edge strength is essential for evaluating performance
under different cutting conditions and materials.
- Application Information: Each insert is often designed for specific cutting operations
(turning, milling, etc.) and materials (aluminum, hardened steel,
etc.).
