FX105
New ceramic inserts for cast iron high speed machining
TZ120- TZ120 ceramic grade with high strength and excellent
wear resistance by adding ZrO2 to Al2O3 with high
oxidation resistance
- Each components are well dispersed to improve fracture
resistance and boundary wear resistance
- Suitable for dry roughing and finishing of special cast iron
(cylinder liner, etc.)
APPLICATION RANGE
TZ120 (Al2O3-ZrO2)
- Excellent wear resistance - High speed continuous turning of cast
iron without coolant
LX21 (Al2O3-TiC)
- High hardness and moderate fracture toughness
- General turning of cast iron
FX105 (Si3N4)
- Mechanical and thermal shock resistance- Interrupted & rough machining
