Sandvik Coromant has launched the CoroMill Plura barrel, a new family of optimized solid end mills designed specifically for profiling applications. This new solution provides high process security, significant productivity gains and cycle time reductions of up to 90%, making it well suited for medical, oil and gas, aerospace, power generation, 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. With its unique one-radius barrel form featuring up to six optimized flutes, CoroMill Plura barrel is an ideal complement to the range.
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 superior surface finishes and lower surface roughness. Despite generating higher forces, the stability and process reliability of barrel end mills make them an ideal choice for achieving precise finishes in demanding profiling applications.
“CoroMill Plura barrel excels in applications requiring precision and superior surface quality,” says Liam Haglington, product manager for solid carbide milling tools at Sandvik Coromant. “Its large cutting edge radius increases step-over and reduces cycle times, boosting productivity during high-volume material removal. The large barrel radius makes it ideal for machining large, complex contours and 3D shapes, while minimizing scalloping for shallow depths of cut. This tool is particularly suited to demanding applications such as aerospace, where components such as engine blisks involve complex geometries and challenging materials. It also enhances profiling in other high-demand sectors like medical, oil and gas, and power generation.”
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.
In line with its commitment to sustainability, 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. By participating, manufacturers not only contribute to environmental sustainability but also benefit from a more resource-efficient and cost-effective production process.
