Allotrope Two or more different physical forms in which an element can exist. Graphite and diamond are allotropes of carbon.
cBN Is the second hardest material after diamond; particularly suitable for machining ferrous materials.
EDG Electric Discharge Grinding is a process similar to electric discharge machining (EDM), except that, a rotating electrode is used.
EDM Electric Discharge Machining is a manufacturing process where material is removed from a workpiece by a series of rapidly recurring electric discharges (sparks). These sparks occur between two electrodes separated by a dielectric liquid.
Laser An acronym for: Light Amplification by Stimulated Emission of Radiation. Lasers cut by focusing the output of a high-power laser on or near the surface of the material to be cut.
PCD PolyCrystalline Diamond.
PCBN Polycrystalline Cubic Boron Nitride.
PCP PolyCrystalline Products i.e. PCD, PCBN and PDC.
PDC Polycrystalline Diamond Cutters - a term used in the oil well bit industry.
Superhard material Superhard material is a material with a hardness value exceeding 40GPa.
Tetrahedral In tetrahedral molecular geometry, an atom is located at the center with 4 substituents located at the corners of a tetrahedron. The bond angles are 109.5° when all 4 substituents are the same, as in methane and diamond.
