Sandvik Coromant has launched a new series of end mills designed to deliver high performance and security in side milling and pocketing operations. The CoroMill® Plura HFS (high feed side milling) end mills are developed for steels and stainless steel applications, but they can also enhance productivity in difficult-to-machine materials such as heat-resistant super alloys and titanium. By utilising the complete cutting length of the end mill, CoroMill® Plura HFS achieves a higher metal removal rate with smaller diameters, compared to indexable milling and traditional milling strategies.
CoroMill Plura HFS features include: an unequal helix flute design that assures a variable angular pitch in every axial section to increase the chatter-free material removal rate, an asymmetrical chip-breaker profile that improves chip evacuation and minimises the risk of edge chipping and tool breakage, a conical core shape with a smaller core diameter at the face to improve chip evacuation capabilities, with a larger core diameter at APMX for maximum stability. Its tough GC1740 grade is developed to manage large ap/ae combinations and resist the bending forces generated when using a 4xDC length of cut. Ultimately, the new Tailor Made offered by Sandvik Coromant includes CoroMill® Plura end mills for manufacturers or machine shops needing a 5xDC length of cut.
