PCBN Inserts

1) Brazed PCBN Inserts

Brazed PCBN (Polycrystalline Cubic Boron Nitride) Inserts are high-performance cutting tools designed for precision machining of hardened and abrasive materials. In these inserts, a PCBN cutting tip is securely brazed onto a carbide body, combining the extreme hardness of PCBN with the toughness and cost-efficiency of carbide.

Ideal for hard turning applications, Brazed PCBN Inserts deliver exceptional wear resistance, dimensional accuracy, and surface finish when machining hardened steels (45–68 HRC), cast iron, and powder metal components. They are widely used in automotive, bearing, and tooling industries where grinding replacement is required.

Key Features:

Extreme Hardness & Wear Resistance: PCBN cutting edge offers outstanding resistance to abrasion in hardened materials.

High Dimensional Accuracy: Ensures precise tolerances and consistent machining results.

Cost-Effective PCBN Solution: Brazed design reduces cost compared to full-solid PCBN inserts.

Excellent Surface Finish: Produces fine surface quality, often eliminating secondary grinding operations.

High Thermal Stability: Maintains edge integrity at elevated cutting temperatures.

Suitable for Dry Machining: Performs efficiently without coolant in hard turning applications.

Strong Carbide Support Body: Provides mechanical stability and shock resistance during cutting.

2) Solid Corner PCBN Inserts

Solid Corner PCBN (Polycrystalline Cubic Boron Nitride) Inserts are ultra-high-performance cutting tools designed for precision hard turning and finishing applications. Unlike brazed PCBN inserts, these inserts feature a solid PCBN cutting corner, delivering maximum edge integrity, superior wear resistance, and extended tool life in extreme machining conditions.

Engineered for continuous and light interrupted cuts, Solid Corner PCBN Inserts provide exceptional dimensional accuracy and surface finish when machining hardened steels (55–70 HRC), cast iron, and powder metal components. They are widely used in automotive, bearing, and tooling industries as a high-efficiency alternative to grinding.

Key Features:

Solid PCBN Cutting Corner: Provides superior edge strength and longer tool life compared to brazed PCBN tips.

Extreme Wear Resistance: Withstands severe abrasion in hardened and heat-treated materials.

Outstanding Surface Finish: Produces high-quality finishes suitable for grinding replacement.

High Dimensional Stability: Maintains tight tolerances even during long machining cycles.

Excellent Thermal Stability: Performs reliably at high cutting temperatures without edge degradation.

Ideal for Hard Turning Applications: Optimized for hardened steel, cast iron, and powder metallurgy components.

Dry Machining Capability: Designed to run without coolant, improving process efficiency.

Example:

CNGN 120408 – Solid Corner PCBN Insert

Type: CNGN (80° diamond, solid PCBN corner)

Size: 12 mm

Application: Hard turning & finishing

Material: Solid corner PCBN

Coating: Not required

Features:

Suitable for hardened steels up to 70 HRC
Excellent wear resistance in continuous cutting
Superior edge stability compared to brazed PCBN
Produces consistent surface finish and dimensional accuracy
Ideal for precision automotive and bearing components

3) Solid PCBN Inserts

Solid PCBN (Polycrystalline Cubic Boron Nitride) Inserts are ultra-hard cutting tools designed for precision machining of hardened steels, cast irons, and other high-strength alloys. Unlike brazed variants, Solid PCBN Inserts are made entirely from PCBN, offering maximum edge integrity, superior wear resistance, and long-lasting performance under extreme cutting conditions.

Ideal for hard turning, finishing, and high-precision applications, these inserts maintain dimensional accuracy and excellent surface finish even in continuous or high-speed operations. They are widely used in automotive, aerospace, bearing, and tooling industries as a high-efficiency alternative to grinding.

Key Features:

100% Solid PCBN Construction: Delivers unmatched edge strength, rigidity, and longevity compared to brazed inserts.

Extreme Wear Resistance: Handles severe abrasion and maintains performance on hardened materials up to 70 HRC.

Exceptional Surface Finish: Produces mirror-like finishes suitable for precision components and high-tolerance applications.

High Thermal Stability: Maintains edge integrity at elevated temperatures, enabling high-speed and continuous machining.

Superior Dimensional Accuracy: Ensures tight tolerances and consistent machining results.

Ideal for Hard Turning: Optimized for machining hardened steel, cast iron, and powder metallurgy components.

Dry or Minimal Coolant Machining: Performs efficiently without coolant, improving cost-effectiveness and productivity.

Example:

CNGN 120408 – Solid PCBN Insert
