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, Sandvik Coromant says. With regard to tool bodies, additive manufacturing allows for the generation of shapes and features not possible with metalcutting. Additionally, virtually any material can be printed, as in this case, a titanium alloy.

Process security is paramount in a number of metalcutting applications, not least when milling with long overhangs, which is a common requirement in components used by the aerospace and oil and gas sectors. Here, the generation of features such as deep cavities can be compromised by vibration, leading to slower production, shorter tool life and poor surface finish. The lightweight CoroMill 390 provides the solution. Combined with Silent Tools milling adapters, this optimized tooling combination subdues vibration to help maximize productivity and process security in demanding applications involving long overhangs. In addition, the tool is designed to deliver light cutting action for smooth cutting performance.

CoroMill 390 can perform long-reach face milling, deep shoulder and side milling, cavity milling and slot milling.The tool is available in 40-mm (arbor 16 coupling) and 50-mm (arbor 22 coupling) diameter variants. Three or four inserts (size 11) can be specified to suit the application. Differential pitch and internal coolant are provided on all cutters.
