PCD Materials

Grafiken-Adico7

ADICO PCD is largely divided into coarse, medium and fine grades. By adjustment of the diamond and binder content ADICO developed 3 series (X, S, and U) to offer the perfect grade for your needs. The characteristics of each types are described in the table below.

Type "X" series "S" series "U" series
Microstructure Characteristics Increased metal binder phase for high mechanical impact resistance.

Little chipping and high grindability during production of PCD tools.

Shows good electrical conductivity, performs with superior cutting speed during EDM processing.
High diamond content, for excellent abrasion resistance due to high hardness.

Reliable performance in a  wide application area. Even fine finish can be achieved in high silicon aluminum.
This series is characterized by a maximized diamond content and an advanced diamond to diamond bonding.

Designed for highly abrasive applications and materials.
Impact Resistance & Abrasion Resistance Despite high mechanical impact and thermal impact resistance, relatively low abrasion resistance Excellent abrasion resistance due to high hardness Compared to “S” series, this series is made by maximizing the content of diamond and by maximizing diamond-to-diamond bondings, so that it can be made very hard and highly abrasion-resistance. However, there is less metal binder, which relatively deteriorates wire EDM cuttability




Grindability Little chipping, high grindability when making PCD tools Relatively more wheel consumption for making PCD tools
Built-Up Edge Relatively a bit of built-up edge if Al finish is done Little built-up edge in case of Al finish
Electrical Conductivity Shows good electrical conductivity, perform with superior cutting speed during EDM processing, no edge burning. Fit with EDM process for specified shape. Compared to conventional PCD, featuring good electrical conductivity, easy for EDM finish
Overall Divided into coarse, medium, and fine grades, with unique properties (heat resistance, impact resistance, abrasion resistance (stone) Divided into coarse, medium, and fine grades, with similar qualities to conventional PCD
Specially Recommended Applications MX: Wooden resin mixture, such as MDF and HDF, which generates a lot of heat during processing
- Coated wood with, for example, SiC Al2O3 
CX: Suitable for interrupted cutting of aluminum 
CS: Outstanding performance and fine finish can be rendered through high silicon aluminum finish
