Tungaloy Ceramic Insert Grade Conquers Turning of Cylinder Liners

Tungaloy Corp. has launched the TZ120 grade ceramic inserts designed 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 line-up of ceramic insert grades to provide a variety of cast iron turning solutions at high speeds.

Its key properties include tough ceramic grade with chemical and thermal stability, providing 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, the inserts are designed for dry machining only as the use of cutting fluids is detrimental to insert life.
