Sandvik Coromant has launched the CoroMill Plura barrel, a new family of optimized solid end mills designed specifically for profiling applications. This solution is engineered to provide high process security, productivity gains and cycle time reductions of up to 90%, making it suited for the aerospace industry and other high-demand sectors.
"CoroMill Plura barrel offers a new machining principal for profiling tools, marking a unique addition to a comprehensive range of end mill solutions for ISO S profiling applications, including CoroMill Plura ball nose, CoroMill Plura lollipop and CoroMill Plura conical ball nose," said a company spokesperson. "With its unique one-radius barrel form featuring up to six optimized flutes, CoroMill Plura barrel is an ideal complement to the range."
The spokesperson continued: "The CoroMill Plura barrel's increased contact radius offers substantial advantages over traditional ball nose machining strategies. This design reduces cycle times by up to 90% by increasing the step-over, which not only enhances machining efficiency by significantly increasing the surface removal rate (SRR), but also ensures exceptional surface quality."
The optimized barrel design reduces cusp height between passes, leading to enhanced surface finishes and lower surface roughness. Despite generating higher forces, the stability and process reliability of barrel end mills make them suited for achieving precise finishes in demanding profiling applications, according to the company.
The tool is available with Sandvik Coromant's internally developed, material-specific grades, including T2CH for titanium alloys and R2AH for heat-resistant superalloys (HRSA). Both are enhanced by Sandvik Coromant's Zertivo 2.0 PVD coating for improved durability and wear resistance. For customers with specific size and diameter requirements, the tool can be customized through Sandvik Coromant's Tailor Made service, and the CoroPlus Tool Guide platform can further aid application needs with expert tooling advice.
"Results achieved thus far demonstrate the tool's reliability and productivity," said Liam Haglington, Product Manager for Solid Carbide Milling Tools at Sandvik Coromant. "For a customer machining an Inconel engine blisk, a machining strategy with CoroMill Plura barrel resulted in a cycle-time reduction of more than 40%. Here, reaching 88 minutes of operation, a 50% increase in tool life was achieved compared to the customer's existing solution. In another case, this time with a titanium blisk, a customer saved over 90 minutes of machining time when using this product over a competitor's conical ball nose solution."
Sandvik Coromant also offers a comprehensive recycling program for worn-out carbide tools, including CoroMill Plura barrel and other advanced milling solutions. This service allows customers to return used tools for responsible recycling, reducing industrial waste and conserving critical materials like tungsten and cobalt.
