POLYCRYSTALLINE CVD Diamond for Dressing Tools

The DC arc Plasma Jet fabrication technique is used to create dressings logs that contain an exceptionally high concentration of atomic hydrogen. As a result, these logs have significantly higher thermal conductivity compared to other methods, even at high growth rates. This attribute proves advantageous for high-speed dressing operations. Additionally, the logs possess increased fracture strength, fracture toughness, and thermal oxidation resistance, along with their superior thermal conductivity. These properties collectively make them an ideal choice for high performance dressing. Furthermore, since they are made of polycrystalline material, they also exhibit orientation independence.

APPLICATIONS

These CVD products are compatible with various types of dressers, including single-point, multi-point, blade, rotary, and roller. The selection of the appropriate dresser size depends on the specific application, and we are happy to provide recommendations upon request.

KEY ADVANTAGES

• Exceptional resistance to chipping and fracture, ensuring prolonged wear
• Consistent wear resistance across the entire length of the dresser
• Performance remains unaffected by dressing orientation
• Outstanding thermal stability for reliable operation
• Diamond composition without any binder phase, ensuring optimal performance

CVD POLYCRYSTALLINE CUTTING TOOL BLANKS

Our DC arc Plasma Jet technique generates a high concentration of atomic hydrogen, resulting in cutting tool blanks with exceptional thermal conductivity.
