Ceramic inserts high speed machine Inconel
Ceramic cutting tool inserts has been introduced for machining 'exotic' alloys such as the high speed machining of Inconel 718 providing exceptional reductions in machining cycle time.
The SX1 grade not only provides efficient machining of grey cast iron, but its performance under high speed machining conditions is the envy of the competition.
Combined with notch style clamping, the SX1 gives the end user long and predictable tool life.
This clamping method ensures that insert movement is eliminated even under the most severe of cutting conditions.
To further enhance tool life and performance, the insert design has added thickness to reduce the possibility of any insert breakage.
Ideal for the machining of cast iron at high speed, the SX1 has a high fracture toughness that gives the end user guaranteed reliability.
This new grade can be applied to rough turning of cast iron and nodular cast iron in the region of 300-1000m/min and 250-450m/min respectively.
For rough and finish machining of cast iron and nodular cast iron, the SX1 can operate at 500-1000m/min and 300-600m/min respectively.
These operating speeds are achieved under dry cutting conditions.
This is an added bonus as dry machining eliminates the need for potentially environmentally damaging and expensive cutting fluids.
This extremely high performance level is enabled by the reduction of a binder element.
The change from an inter-granular phase of silicon nitride particles for a higher melting point compound allows the SX1 to operate beyond the realms of competitor products.
This specially engineered method of production ensures the SX1 can outperform competitor products at not only the conventional silicon nitride application range, but also at the high speed ranges.
