  MACHINING with POLYCRYSTALLINE DIAMOND
   What is POLYCRYSTALLINE DIAMOND?

 

    

    Diamond is the hardest, most abrasive-resistant, material known to man. These properties make     diamond an ideal cutting tool. Within the crystal structure, however, fracture planes, used by the     diamond cutter to produce the gem diamond from the rough, can cause catastrophic breakage
    of the tool edge, when subjected to impact.
 
     
    DR-PCD tools incorporate Polycrystalline Diamond blanks produced under conditions of high pressure
    (1 million PSI) and temperature (1700 Degrees C), similar to those of diamond synthesis. Randomly     orientated, carefully selected synthetic diamond crystals are grown together on a hard metal substrate.
 
    This results in a material with the hardness, abrasive resistance and high thermal conductivity of      diamond with the toughness of hard metal.
 
    Using the hard metal substrate the PCD blank is brazed to a carrier, either steel or hard metal, and 
    machined by grinding or E.D.M to produce the cutting edge.
 
     When compared to other cutting tool materials, there are three main reasons for using
    DR-PCD tools:-
 
            Increased tool life results in reduced tool cost per component and less idle
         machine time.
 
            Increasing cutting speed  improves productivity through reduced cycle times.
 
            Grinding and other less productive machining methods can be replaced by
        DR-PCD milling and turning.
