How do I choose the right carbide insert?_copy20251230

The choice of carbide insert depends on the material you’re working with, the type of cut you’re making, and the machine you’re using.

Can carbide inserts break?_copy20251230

While carbide inserts are extremely durable, they can break under excessive force or if used improperly.

How do I maintain my carbide inserts?_copy20251230

Regular cleaning and proper storage can help maintain the longevity of your carbide inserts. Also, avoid using them on inappropriate materials or at incorrect speeds.

Superhard materials are defined as materials with a Vickers hardness exceeding 40 GPa. They include the hardest natural material—natural diamond—as well as synthetic diamond and cubic boron nitride (CBN).

Since the first commercially viable polycrystalline diamond (PCD) product was released in 1971, research and application of composite superhard materials have entered a new phase of rapid development worldwide. Their product forms have continuously evolved—from basic synthesized abrasives for grinding and cutting, to functional products such as PCD and PCBN cutting tools, saw blades, grinding wheels, and diamond wires, and further to advanced applications in semiconductor heat dissipation and packaging, optical components, and quantum information technologies.

Among them, PCD/PCBN superhard cutting tool materials are widely recognized as the “teeth of modern industry”, playing a critical role in high-efficiency, high-precision, and high-reliability machining.

When to Choose Superhard Materials?

Superhard materials offer unmatched hardness, wear resistance, and chemical stability compared to conventional tool materials.

They are ideal for high-speed, high-efficiency, and high-precision machining — especially in dry cutting and in applications replacing grinding with turning or milling.

For machining highly wear-resistant materials, tough alloys, or advanced composites, superhard cutting tools enable higher cutting speeds, greater depth of cut, improved surface finish, and stable performance.

In mass and automated production, they significantly increase productivity and yield while reducing secondary operations and overall manufacturing costs.

Why Choose CYC?

With over 20 years of expertise in hard materials, CY Carbide operates under a certified ISO 9001:2015 quality system (TÜV Rheinland), supported by full traceability and rigorous quality control.

We offer strong customized R&D and advanced manufacturing capabilities, ensuring fast and reliable delivery from material to finished product.

Through collaboration with the Institute for Superhard Materials of the National Academy of Sciences of Ukraine, we established a China–Ukraine Joint Laboratory and independently developed a complete range of PCD and PCBN composite and solid tool materials, mastering core superhard technology.

FAQs of Superhard Materials



What Is the Difference Between Superhard Materials and Cemented Carbide?

 

Cemented carbide is a metal-matrix composite produced by powder metallurgy, while PCD and PCBN are covalently bonded crystalline materials synthesized under ultra-high temperature and pressure.

This fundamental structural difference results in dramatically superior hardness, wear resistance, and chemical stability for superhard materials.



Why Can Chipping or Rapid Wear Still Occur with Superhard Tools?

 

Extreme hardness also means inherent brittleness.

Proper edge preparation, rigid clamping, and optimized parameters are essential to fully leverage their performance.



Are There Special Requirements When Using Superhard Tools?

 

Accurate tool setting and trial cutting are recommended before mass production.

PCBN is typically used in dry or MQL conditions, while PCD requires high-pressure coolant to prevent thermal damage and ensure chip evacuation.



Why Are Superhard Tools More Expensive?

 

Their production involves ultra-high-pressure synthesis, advanced equipment, and strict process control, resulting in higher manufacturing costs.

However, their significantly longer tool life can greatly reduce cost per part in high-value applications.
