This tool is designed for milling abrasive composite materials. It is intended for ISO O materials and offers significant advantages in terms of productivity, tool life, and process reliability.
Machining composite materials has long been associated with challenges such as delamination, uncut fibers, vibrations, and rapid tool wear. The CoroMill Plura Composite 2P350 addresses these issues with its patented double-cut mechanism. This allows for a controlled, shear-like cutting action, resulting in stable and predictable machining.
The new grade O2AD has been specifically developed for machining abrasive composite materials. The strong adhesion between the CVD diamond coating and the tailored substrate ensures top performance and consistent quality. Results from practical tests show up to 100 percent longer tool life compared to the previous grade O12M.
‘The CoroMill Plura Composite 2P350 was developed to address the most common challenges in machining composite materials. These include rapid wear and unpredictable performance caused by abrasive and heat-sensitive materials,’ reports Liam Haglington, product manager for solid carbide end mills at Sandvik Coromant. ‘The quality of the components is critical, and issues such as delamination and uncut fibers can compromise their integrity and quality.’
The CoroMill Plura Composite 2P350 is suitable for a variety of demanding composite material applications, including slot milling, inclined plunging, and edge milling. Its large chip channel volume allows for efficient chip removal and high cutting performance. At the same time, the low-vibration cutting behavior ensures reduced noise levels during machining.
Aerospace companies manufacturing fuselage structures, wings, stabilizers, spars, ribs, and frames can benefit from significant improvements in part quality and productivity. However, other industries, such as automotive, defense, as well as space and maritime industries, can also benefit from the clear performance advantages of the tool.
‘One of the most common pieces of feedback we receive about this tool is that it works consistently regardless of the machining conditions, workpiece, or tool holder,’ adds Haglington. ‘For those seeking safe, reliable, and high-performance composite machining, the CoroMill Plura Composite 2P350 is the right choice in every respect.’
