Tungaloy’s New TZ120 Ceramic Insert Grade Conquers Turning of Cylinder Liners

Tungaloy is introducing TZ120 grade ceramic inserts designed for turning cast iron at high cutting speeds.

TZ120 ceramic grade is developed for efficient machining of cast iron. A zirconia-toughened aluminum oxide grade with superior thermal properties, TZ120 enables extended tool life and process security at high cutting speeds, making the grade ideal for high-speed, dry machining of centrifugally cast cylinder liners . The new grade will allow Tungaloy’s extensive lineup of ceramic insert grades to provide a variety of cast iron turning solutions at high speeds.

Key Properties:

• Tough ceramic grade with chemical and thermal stability provides excellent resistance to strong acids at elevated temperatures
• The uniform distribution of the zirconia grains in the alumina matrix imparts superior fracture and notch wear resistance, preventing premature insert failure during demanding operations
• Ideal for machining of centrifugally cast iron cylinder liners
• Designed for dry machining only — the use of cutting fluids is detrimental to insert life
• Introducing 6 inserts
