Sandvik Coromant, Sandviken, Sweden, has introduced a lightweight metal cutting tool, the CoroMill 360®, which incorporates a metal additively manufactured cutter body. According to the company, the use of AM enabled the tool to be produced at a lighter overall weight, helping to minimise vibration.

The CoroMill 360 provides a solution for the generation of features like deep cavities which can be compromised by vibration, leading to slower production, shorter tool life and poor surface finish. Combined with the company’s Silent Tools™ milling adaptors, the optimised tooling combination subdues vibration to help maximise productivity and process security in demanding applications involving long overhangs.

The CoroMill 390 is reportedly capable of performing long-reach face milling, deep shoulder and side milling, cavity milling, and slot milling. Thomas Wikgren, Manager Product Application Management, Sandvik Coromant, stated, “When designing our new lightweight CoroMill 390, material has been tactically removed to create the optimal cutter design for minimizing mass.”

“This is called topological optimisation 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,” he continued. “Moreover, a shorter distance between the damper in the adaptor and the cutting edge improves performance and process security.”
