Machining thin walls and ribs
Plastic injection moulds and die casting moulds often have ribs and thin walls. Ribs, for example, are increasingly being milled, as this process is more cost-effective than EDM (spark eroding). As a rule, long or extra-long carbide tools with small diameters are used. Customer-specific solutions (RibCutter) to match the respective rib shape are also possible here
Roughing
Roughing operations are responsible for most of the chip removal capacity. Special milling strategies such as high-feed machining or trochoidal milling can reduce machining time and thus increase profitability. In addition to tools with indexable inserts and solid carbide milling cutters, high-performance milling cutters with special roughing geometry are used.
Finitura
La lavorazione di finitura rimuove le dimensioni residue per ottenere la forma finale. Le dimensioni dei materiali temprati dopo la prefinitura sono pari a 0,05-0,1 mm, mentre quelle dei materiali morbidi a 0,1-0,3 mm. Le frese a profilo sferico e/o a profilo torico sono gli utensili da scegliere in funzione dei profili finali del pezzo da lavorare.
