Less vibration even with longer tools

The new Alesa Delta indexable insert allows higher productivity on modern machining centers.The new Alesa Delta indexable inserts have six ground cutting edges and are mounted tangentially on the milling body. As the Swiss manufacturers explain, this high positive cutting approach not only means small cutting forces but also allows higher productivity on modern machining centers. The high helix angle in combination with the small cutting forces has a positive effect on the spindle load. Depending on the material, the workpiece is also less affected by work hardening and deformations due to strain. The tangential arrangement of the inserts is claimed to produce maximum stiffness in the milling body thanks to stronger cross sections. Further advantages are seen in the good heat transfer and less vibration even in the case of longer tools.
