Sandvik Coromant has introduced a new milling grade for titanium manufacturing, designed to improve tool life predictability, reduce production interruptions and lower the carbon footprint associated with cutting tools.
The metal-cutting solutions specialist said its new GC1250 indexable milling grade combines EthaCore™ carbide technology with Zertivo® nano-multilayer physical vapour deposition (PVD) coating to improve performance when machining titanium alloys.
According to Sandvik Coromant, titanium’s poor thermal conductivity concentrates heat around the cutting edge, increasing the risk of tool wear, chipping and insert failure. The GC1250 grade is designed to withstand changing thermal and mechanical loads, helping manufacturers achieve more consistent tool life and reduce unplanned downtime.
“GC1250 sets a new benchmark for resilience and predictable performance in titanium milling,” said Wayne Mason, global product application manager for grades at Sandvik Coromant.
“By reducing unexpected insert failures and interruptions, this grade can help customers increase machine utilization and achieve more cost-efficient machining.”
The company also said the grade could support manufacturers’ sustainability targets. Its EthaCore™ carbide technology contributes to a lower product carbon footprint compared with leading competitor grades using ruthenium-based carbide in the same application area, according to Sandvik Coromant.
“Performance and sustainability increasingly need to advance together,” Mason said. “GC1250 gives manufacturers a solution that supports secure, productive titanium machining while helping reduce the carbon footprint associated with their tooling.”
GC1250 is designed for roughing to semi-finishing applications in titanium alloys and is intended for wet machining. It is available across Sandvik Coromant’s CoroMill® shoulder, face, groove, high-feed and profile milling product ranges.
The launch also completes the company’s 1200-series grade chain, which Sandvik Coromant said covers all major workpiece material groups and provides access to its latest substrate and coating technologies across a range of machining applications.
