CoroMill 345 inserts from Sandvik Coromant simplify stainless steel milling
When milling stainless steel there are many challenges to overcome, including difficulties with chip formation, tool life and productivity. The latest CoroMill 345 insert geometries from Sandvik Coromant are said to offer the light cutting action and low forces required to surmount such challenges. Benefits include not only higher metal removal rates and greater throughput, but the ability to use CoroMill 345 on small taper machines (ISO 30 and ISO 40), in vibration sensitive applications or where there are weak fixtures, says Sandvik Coromant.
The inserts feature eight edges, four on each side, and although they sit negatively in the cutter, a very high rake ensures positive, light cutting to promote good chip formation in stainless steel. A wiper insert is also available where a brilliant surface finish is sought, while internal coolant is available for cutters up to 125 mm in diameter.
