Sandvik Coromant extends its series of ceramic exchangeable milling heads with a new ceramic grade for optimized performance in nickel-based alloys. The latest, brazed-ceramic CoroMill 316 is said to offer a more productive method for roughing in ISO S materials than standard carbide milling cutters.
With aerospace components manufactured from nickel-based alloys becoming increasingly prevalent, the demand for optimized cutting tools is growing. With this in mind, Sandvik Coromant has developed two solutions for shoulder and face milling of nickel-alloy aero-engine parts.
Ceramic tools retain their hardness at the high temperatures associated with milling heat-resistant super alloys (HRSA), which Sandvik Coromant says can contribute to significant speed increases compared to solid carbide tools. With the new, larger head diameter available from D16-25 mm, it will be possible to reach high RPM cutting speeds with conventional machining centers.
Beyond shoulder and face milling, the new end mills can also be used for pocket milling, helical interpolation, ramping and slot milling.
