Selection of the cutting material types when machining with PCD
Our standard range includes two cutting materials with the following properties:
ADC ADC-S
Polycrystalline diamond as a composite cutting material with a cemented Polycrystalline diamond as a composite cutting material with a cemented
carbide backing with high cutting sharpness and low cutting pressure in a carbide backing (coarse grain)
narrow tolerance field With favourable cutting sharpness and low cutting pressure with narrow
Low wear resistance with high durability tolerances
Fine grain Low wear resistance with high durability
Fine finishing and smoothing of all non-ferrous metals with low proportion of Fine finishing and smoothing of all non-ferrous metals with low proportion of
abrasive filler materials abrasive filler materials
A variety of diamond cutting materials are also available outside of our standard ranges:
MDC DM TFC PD PDC-CU-S DP composite
Solid mono-crystalline diamond without structure. Solid poly-crystalline CVD diamond without binding Solid poly-crystalline diamond cutting material
