Sandvik Coromant 390 Lightweight

In a move designed to offer customers a host of in-process benefits, cutting tool and tooling system specialist Sandvik Coromant is introducing its lightweight CoroMill 390, which features a cutter body produced using additive manufacturing. The lighter overall weight of the tool helps to minimize vibration and improve security during machining with long overhang. In turn, the productivity is also increased. ”When designing our new lightweight CoroMill 390, material has been tactically removed to create the optimal cutter design for minimizing mass,” explains Magnus Engdahl, Product Application Manager, Sandvik Coromant. “This is called topological optimization and it makes the cutter more compact and significantly lighter than a conventional version, thus helping machine shops to boost the productivity of their long-overhang milling operations. Moreover, a shorter distance between the damper in the adaptor and the cutting edge improves performance and process security.”
