Diamnd CBN Material

Diamond and CBN are defined as super hard materials due to their extremely hardness that surpassws the traditional abrasive materials like Aluminum oxide or silicon carbide.
Diamond and CBN Wheels are widely used in high effective grinding processes and offer substantially benefits over traditional wheels.

The main advantage of diamond and CBN wheels:

  • Very long tool life and profile stability;
  • Short grinding times;
  • Short handling times;
  • Lack of thermal damage to the workpiece;
  • Ensure appropriate workpiece quality

Synthetic Diamond Powder

Synthetic Diamond Powder has the characteristics of high thermal stability, high chemical stability, good conductivity, good physical properties and so on. It has high hardness and good wear resistance, and can be widely used for cutting, grinding and drilling such materials as:
  • Hard metal
  • Cermet
  • Hard metal/steel
  • combinations
  • Glass
  • Quartz
  • Ceramic materials of all kinds
  • Ferrotitanite
  • Carbide-based powder coating
  • Graphite
  • Polycrystalline diamond and CBN blanks
  • Ceramic magnetic materials
  • Glass and carbon-fibre reinforced synthetic materials
  • Tungsten Carbide

cubic boron nitride powder (CBN)

CBN is the second material after diamond. CBN is produced similarly to the diamond by high pressure and high temperature aynthesis. Due to their chemical features and considerable lower wear, CBN tools are used for grinding such hard-to-process steels as:
  • Hardened high-speed steel (HSS)
  • High alloyed steels with at least 55 HRC
  • Case-hardened steels
  • Iron-based powder coatings
  • Chill castings
  • Soft steels in certain applications
  • Stellite
