Vacuum PCD Brazing Machine for Diamond Tools


What is PCD Brazing?

PCD brazing refers to the process of joining Polycrystalline Diamond (PCD) materials to a metal substrate using brazing techniques. This process is vital for manufacturing cutting, drilling, and machining tools that require exceptional hardness and wear resistance. 

Vacuum brazing:
PCD, CVD, and MCD Redefined

Let’s go through some different types of materials used in vacuum brazing, where PCD, Chemical Vapor Deposition (CVD), and Mono Crystal Diamond (MCD) are seamlessly amalgamated, enhancing the resilience and efficiency of your cutting tools.

Vacuum Brazing of PCD

Let the vacuum brazing PCD technology bolster your tool’s performance through enhanced bonding, ensuring impeccable toughness and reducing the vulnerability to potential breakages.


What is PCD?

PCD stands for Polycrystalline Diamond (PCD), a superhard material composed of tiny diamond crystals sintered together at high temperatures and pressures. It is widely used in cutting tools due to its exceptional properties:
  • Extreme hardness: PCD is almost as hard as natural diamond, making it ideal for machining hard materials like ceramics, composites, and certain metals.
  • Excellent wear resistance: PCD retains its sharpness for extended periods, reducing tool wear and downtime.
  • High thermal conductivity: PCD efficiently dissipates heat generated during cutting, reducing thermal damage and improving tool life.

Exploring Vacuum Brazing with CVD

With our innovative techniques, find the perfect blend of coalescence between diamonds, optimizing for superior wear resistance and longevity in your operations.

What is CVD?

Chemical Vapor Deposition (CVD) is a thin-film deposition technique where a solid film is deposited on a substrate from a gaseous precursor. In the context of brazing, CVD could refer to a process where a coating is deposited on the diamond particles or the tool substrate to improve its properties, such as adhesion, heat resistance, or abrasion resistance.


Vacuum brazing: Exclusive for Mono Crystal Diamonds 

Take your MCDs to the next level with vacuum brazing, the only way to effectively braze single crystal diamonds without damaging their properties and qualities.. This oxygen-free process eliminates weak points, resulting in superior toughness and reduced breakage. 

What is MCD?

Also known as Mono Crystal Diamond or interchangeable with Single Crystal Diamond (SC), MCD is a synthetic diamond created in a lab with a unique single-crystal structure. This means the entire diamond is formed from a single, uniform lattice of atomsThese diamonds are extremely hard and wear-resistant but can be brittle and susceptible to breakage. They are often used in high-precision cutting applications such as scalpels and optical windows and lenses

Due to this single-crystal structure, MCD boasts exceptional properties:
  • Unmatched Hardness and Wear Resistance: MCD boasts the highest hardness of any natural material, making it ideal for applications demanding extreme cutting precision and durability, like scalpels and optical windows.
  • Superior Thermal Conductivity: MCD efficiently dissipates heat, preventing tool wear and deformation during high-speed machining, resulting in cleaner cuts and longer tool life.
  • Chemically Inert: MCD is virtually resistant to chemical reactions with most materials, making it suitable for cleanroom environments and applications requiring high purity.
  • Optical Properties: Due to its exceptional transparency, MCD finds application in specific optical components like lenses and windows for infrared and ultraviolet wavelengths.
