In a move designed to offer customers a host of in-process benefits, 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.
Additive manufacturing offers a superior way of producing complex structures with high precision and without joints. Use of the process can make components lighter, stronger and more flexible than ever before. With regard to tool bodies, additive manufacturing allows for the generation of shapes and features not possible with metal cutting. In addition, virtually any material can be printed, as in this case, a titanium alloy.
”When designing our new lightweight CoroMill 390, material has been tactically removed to create the optimal cutter design for minimizing mass,” explains Thomas Wikgren, Manager Product Application Management, 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.”
