CoroMill 345® inserts simplify face milling in stainless steel
New generation Sandvik Coromant inserts generate low cutting forces
When milling stainless steel there are many challenges to overcome, including difficulties with chip formation, tool life and productivity. The latest insert geometries for CoroMill 345® have been designed specifically to offer the light cutting action and low forces required to surmount such challenges. Numerous 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 machines), in vibration sensitive applications or where there are weak fixtures.
The innovative new inserts feature eight edges, four on each side, and although they sit negatively in the cutter, a very high rake ensure positive, light cutting. This not only promotes excellent chip formation in stainless steel, but improves the working environment thanks to its soft machining sound. 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.
By way of testimony, outstanding results were achieved in a recent customer performance test. A pump body made from 316L stainless steel was subject to dry roughing operations on a horizontal machining centre. Using CoroMill 345, both cutting speed and feed speed could be increased against a competitor cutter. This helped deliver 50 per cent more components with 22 per cent higher metal removal rate, without wearing out the inserts. In fact, using the new inserts, three components per edge could be achieved, against just two using the competitor cutter.
