Technical Data

Polycrystalline Diamond

Polycrystalline Diamond, PCD, is the hardest known material and has many advantages in manufacturing.

PCD is a synthetic diamond produced by sintering together micron-sized pieces of diamond powder with a metal binder, typically cobalt, under extreme pressure and temperatures. The cobalt adds toughness to the material and renders the material electrical conductive.  The carbide substrate provides a brazeable layer of material.  PCD is cut using a wire EDM, electrical discharge machine. The PCD is then adhered to the tooling body by brazing and then finished machined to design specifications. 

PCD is extremely abrasion resistant and PCD tools can have a 50-100 times longer tool life compared to conventional tools.  PCD is recommended for machining non-ferrous and non-metallic materials such as aluminum, brass, composite materials, copper, fiberglass, green ceramics and carbides.    We choose the most appropriate grade of PCD for your specific application as we balance the importance of wear resistance, strength and surface finish. 

Polycrystalline Cubic Boron Nitride

Polycrystalline Cubic Boron Nitride, CBN, is the seconded hardest known material after PCD and has many advantages in manufacturing.

CBN is produced by sintering together micron-sized pieces of cubic boron nitride with ceramic materials under extreme pressure and temperatures.  The carbide substrate provides a brazeable layer of material.  CBN is cut using a wire EDM, electrical discharge machine. The PCD is then adhered to the tooling body by brazing and then finished machined to design specifications. 

CBN is extremely abrasion resistant and has a high thermal stability.   CBN is recommended for machining ferrous materials such hardened steels, cast iron, powdered metals and super alloys.  We choose the most appropriate grade of CBN for your specific application as we balance the importance of chemical wear resistance, abrasion resistance and surface finish.
