Metals such as heat-resistant superalloys and titanium can be really difficult, but with the right approach and guidance in machining, tool holding and insert selection, machine operators can overcome the problem areas.
From implantable joints in the human body to big parts for marine facilities in the oil industry to engine turbines in aerospace, heat-resistant superalloys and other alloys are being used regularly across major manufacturing segments. But they can be arduous to machine.
If the goal is to make parts at the highest quality in the least amount of time, then having an understanding of the kind of tooling to use is essential. No one wants to burn through tools or cause production delays because of super dense, hard metals that rev up the machine but cut super slow or inaccurately. Having an understanding of a machine’s capabilities is essential too—as is knowing the tools that will work the best for the tough materials.
“The primary application for HRSAs is hot zone turbine components for both aircraft and power generation—parts like blades, blisks, brackets, valves, and manifolds, most of which are complex and contoured,” writes Ed Sinkora for Advanced Manufacturing in the article “Hot Techniques for Cutting High-Temperature Alloys.”
“That means using 5-axis milling to achieve the required forms and tolerances in one clamping. And for smaller parts, solid-carbide round tools are needed, requiring particularly stiff tool holders,” explains Sinkora.
Many industries are under manufacturing pressure. The time it takes to achieve quality parts really matters, especially in very competitive markets.
“The main focus is on process reliability since these structural components are extremely expensive,” notes Walter Tools in an article about pocket milling titanium in aerospace. “At the same time, cost pressure from the market demands high machining and productivity performance.”
To get to that comfortable level of “process reliability,” there is a lot of know-how with using the right machines, workholding, tooling, toolpaths and coolant—all together—find machining and tooling professionals. We explore the top tooling and machining guidance for titanium, HRSAs and alloys.
