Sandvik Coromant Solid End Mill Enhances Profiling Efficiency

Source: Sandvik Coromant

Sandvik Coromant’s Coromill Plura Barrel line of solid end mills are designed specifically for profiling applications. This solution provides high process security, notable productivity gains and significant cycle time reductions, making it well suited for the aerospace industry and other high-demand sectors.

The Coromill Plura Barrel offers a machining principle for profiling tools, marking a specialized addition to the company’s end mill solutions for ISO S profiling applications, including Coromill Plura Ball Nose, Coromill Plura Lollipop and Coromill Plura Conical Ball Nose. The tool features a one-radius barrel form featuring up to six optimized flutes.

The increased contact radius of the Coromill Plura Barrel is said to provide several advantages over traditional ball-nose machining strategies. This design can reduce cycle times by up to 90% by increasing the step-over, which improves machining efficiency by significantly increasing the surface removal rate (SRR) while also promoting 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 well suited for achieving precise finishes in demanding profiling applications.

According to Liam Haglington, product manager for solid carbide milling tools at Sandvik Coromant, the Coromill Plura Barrel’s large cutting edge radius increases step-over and reduces cycle times, boosting productivity during high-volume material removal. The large barrel radius makes it well suited for machining large, complex contours and 3D shapes, while minimizing scalloping for shallow depths of cut. This tool is particularly suited to demanding applications like aerospace, where components such as engine blisks involve complex geometries and challenging materials. It also improves 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 a custom phyiscal vapor deposition (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 a tool guide platform can further aid application needs with expert tooling advice.

Sandvik Coromant also offers a comprehensive recycling program for worn-out carbide tools, including the Coromill Plura Barrel and other advanced milling solutions. This service enables customers to return used tools for responsible recycling, reducing industrial waste and conserving critical materials like tungsten and cobalt. By participating, manufacturers can contribute to environmental sustainability and benefit from a more resource-efficient production process.
