山特维克可乐满推出 GC1250 铣削材质，面向钛合金加工
New milling grade supports predictable tool life in titanium machining
山特维克可乐满（Sandvik Coromant）推出可转位铣削材质 GC1250，用于钛合金加工。该材质将 EthaCore 硬质合金技术与纳米多层 PVD 涂层结合，采用全新的材质架构，由专利 EthaCore 硬质合金平台与 Zertivo 纳米多层 PVD 涂层技术组成，旨在提升抗冲击性、刀具寿命和加工过程安全性，并降低环境影响。 钛合金导热性差，热量集中在切削刃上，容易造成快速磨损、崩刃和刀片意外失效。GC1250 的基体设计用于适应变化的热负荷与机械负荷，从而带来更可预测的刀具寿命、更少的意外破损和更低的停机时间。山特维克可乐满材质全球产品应用经理 Wayne Mason 表示，该材质可减少刀片意外失效与中断，帮助客户提高机床利用率、降低加工成本。 在可持续性方面，EthaCore 使该产品的碳足迹明显低于该应用领域使用钌基硬质合金的主要竞品材质。GC1250 针对钛合金的粗加工到半精加工优化，适用于湿式加工，覆盖 CoroMill 方肩、面铣、槽铣、高进给和仿形铣削系列。该材质的推出也补齐了 1200 系列材质链，形成覆盖主要工件材料组的完整产品组合。
Metal cutting tool and manufacturing solutions specialist Sandvik Coromant has created indexable milling grade GC1250, a new grade for titanium alloy machining. The grade combines its EthaCore
carbide technology with a nano-multilayer physical vapor deposition (PVD) coating to improve resilience, tool life, process security and reduce environmental impact.
Titanium’s poor thermal conductivity concentrates extreme heat at the cutting edge, increasing the risk of rapid wear, chipping and unexpected insert failure. GC1250 addresses these challenges with a completely new grade architecture combining Sandvik Coromant’s patented EthaCore carbide platform and its Zertivo® nano-multilayer PVD coating technology.
The product’s customer value is built around three pillars: innovation, performance and sustainability. Its resilient substrate is designed to adapt to changing thermal and mechanical loads, helping deliver more predictable tool life, fewer unexpected breakages and reduced production downtime.
“GC1250 sets a new benchmark for resilience and predictable performance in titanium milling,” says 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.”
Grade GC1250 also helps customers work toward their sustainability targets. EthaCore contributes to a substantially lower product carbon footprint than leading competitor grades that use ruthenium-based carbide in this application area. “Performance and sustainability increasingly need to advance together,” adds Mr Mason. “GC1250 gives manufacturers a solution that supports secure, productive titanium machining while helping reduce the carbon footprint associated with their tooling.”
Grade GC1250 is optimized for roughing to semi-finishing of titanium alloys. It is designed for wet machining and is available across a broad range of CoroMill® shoulder, face, groove, high-feed and profile milling concepts. The introduction of grade GC1250 also completes the 1200-series grade chain, creating a comprehensive portfolio covering all major workpiece material groups. Customers can now access the latest substrate and coating technologies across a wide range of machining applications.
Together with our customers and partners, Sandvik Coromant supplies tooling solutions to the world’s engineering industries.
