Benefits of Compax™

Hyperion Materials & Technologies' Compax™ polycrystalline diamond (PCD) laminated blank design combines high hardness, high abrasion resistance, low coefficient of friction, and good impact resistance. The cemented tungsten carbide substrate of the blank provides mechanical support to the diamond abrasive layer, increases its impact strength, and also allows ease of braze attachment in finished tool fabrication.

Hyperion has developed a new line of Compax™ PCD, Compax2.0™.  The first grade in this new line, SE (Superior Edge), was created specifically for milling where an extra sharp edge with superior toughness is critical.

Compax PCD cutting blanks are most widely applied in machining nonferrous and nonmetallic materials. They have become a global industry standard for enhanced part quality and significant cost reductions in the overall production cycle:

  • Higher material removal rates and improved cycle times, providing more parts per shift
  • Cutting speeds significantly faster than those of conventional cutting tools
  • Highly improved workpiece quality, excellent dimensional control, consistent surface finishes, and reduced scrap
  • Longer tool life resulting in increased machine up-time, providing greater production capacity without investing in new equipment.
