Dianat (natural diamond) Monosynt (synthetic monocrystalline diamond)
DM
Highest hardness, absolutely notch- free cutting edges, low fracture toughness.
Superfinishing of all NF metals (non- ferrous) and NF materials without abrasive fillers, plastics and acrylic glass.
Diavap
CVD-D
Without carbide base and without metallic binder phase, 99.9 % diamond, notch-free cutting edges, highest wear resistance, low fracture toughness.
NF metals
Plastics with abrasive fillers Graphite
Carbide
Ceramic
Diasynt-U ultrafine grain
DP
Polycrystalline diamond with carbide base, ultrafine grain, good cutting sharpness and very low cutting pressure in case of tight tolerances. Good wear resistance and durability.
Finest coating of all NF materials with very low percentage of abrasive fillers.
Diasynt-F fine grain
DP
Polycrystalline diamond with carbide base, fine grain, good cutting sharp- ness and low cutting pressure in case of tight tolerances.
Fine finishing and finishing all NF metals and materials with low percentage of abrasive fillers.
Diatsynt-G rough grain
DP
Polycrystalline diamond with carbide base, good wear resistance and good fracture toughness.
All NF metals and materials, high percentage of abrasive fillers from rough machining to finishing.
Cubor
CBN
High level of wear resistance, hot hardness, compression strength and durability.
Finishing hardened steels
from 45 HRc to 70 HRc Sintered steels
Gray cast iron / chilled cast iron Ni carbide superalloys.
