When milling super alloys, there are certain process requirements that must be observed.

I don’t hear heat-resistant super alloys (HRSAs) referred to as “exotic materials” or “exotics” all that much lately. Perhaps that’s because materials such as Inconel and Waspaloy have now become far from exotic for an increased number of shops. The metals, if not everyday materials for these shops, are seen at least every week or every month.
As demand for HRSA components has increased, shops such as these have confronted a need to become consistently more productive at machining these metals. A great starting point can be found here—in a list of bullet points from Sandvik Coromant that summarizes some of the most basic process considerations for milling HRSA materials effectively.

The article is part of the Milling Aerospace Alloys area of Sandvik’s new online knowledge center devoted to Titanium & HRSA Machining. If you are struggling to obtain more productivity in any of these high-temperature aerospace metals, take a moment to click through the resources that Sandvik Coromant has gathered together here. 


  • A Model Camshaft Grinding Process

    Optimizing a camshaft lobe grinding cycle has traditionally been based less on science and more on educated guesswork and numerous test grinds. Now, computer thermal modeling software can predict areas where lobe burning is likely to occur, in order to determine the fastest possible work speed that won't thermally damage lobes and greatly reduce the number of requisite test grinds.

    Choose cutters, depths and tool paths with attention to particular steps in the process, and you can machine titanium more efficiently than you might suspect. Boeing offers practical tips.

  • When Spindle Speed is a Constraint

    Though it won’t replace high speed machining, Boeing sees “low speed machining” as a viable supplement to higher-rpm machines. Using new tools and techniques, a shop’s lower-rpm machining centers can realize much more of their potential productivity in milling aluminum aircraft parts.
