Ceramics-based indexable faceted cutting inserts (IFCI)

Description

These indexable faceted cutting inserts (IFCIs) are made of the following ceramics:

Pure alumina-base ceramic
Doped alumina-based ceramic
Nitride ceramic.

Main advantages as compared to state-of-the-art hard metals:

Resistance to thermo-mechanical shocks
High wear-resistance
High thermal stabilit.

Applications

VCS35 IFCIs (alumina-based ceramics) are recommended for high-speed continuous finishing operations in coolant-free turning of cast iron grades (К01-К05).

VCS40, VCS45 IFCIs (doped alumina-based ceramic) are recommended for:

High-speed machining of cast iron grades under favorable parameters (К01-К05);
Prolonged high-speed machining of hardened steel grades (Н05-Н10);
Finishing and semi-finishing of refractory alloys (S01-S10).

VCS05, VCS15 IFCIs (nitride ceramics and doped nitride ceramics) are used for high-speed continuous and discontinuous turning of cast iron grades (K01-K20).

VCS20 IFCIs (SiALON ceramic) are made of ceramic grade recommended for roughing and semi-finishing of the refractory alloys (S05-S20).
