Graphite & Hard Carbon
Diamond coated tools were commercialized more than
20 years ago and have become an established solution for machining
graphite. Diamond and graphite are both forms of carbon, but the chemical
bonds of each material are arranged as differently as the properties
Diamond is the hardest known material, an excellent electrical insulator
and sought after for its hardness and transparent crystal structure.
Graphite is a soft, opaque material whose conductive properties make
it an essential part of fabricating molds and dies. Graphite can also
be an extremely abrasive material that quickly dulls the cutting of
edges of carbide tools during machining.
DiaTiger® CVD diamond coating consists of 100% pure crystalline
diamond, making it more than capable of withstanding the abrasive
forces associated with machining graphite and hard carbon. On average
diamond coated tools exhibit 20 times the tool life of uncoated carbide
and tools coated with Diamond Like Coatings (DLC or Amorphous diamond).
