The Iscar products of the High Qline family of cutting tools offer an indexable milling Insert with an asymmetric shape. This insert opens up opportunities for reduction of vibrations in metalcutting.
The design of the one-sided insert HM90 ADCT 1505-CF follows a different approach compared with traditional milling inserts. The insert has different Helix angles on the two cutting edges, and the two edges are colored gold and black. The concept is to mount gold and black edges alternately, resulting in variable Helix configuration for the cutter.
This feature ensures significant improvement of the cutters’ performance in shoulder milling by reducing vibrations. Typically, the tool life of the insert increases by 15-20 percent, and the power consumption is reduced by 10 percent or more.
This solution is ideally suited for less rigid setup, long overhang applications, thin-walled workpiece, problematic workholding, and so on.
The new asymmetric insert is suitable for the existing Heli-Mil family of milling cutters.
Simulating vibrations is difficult: It depends on many factors. In the design stage, simulation does not always help to find the geometry of a vibration-proof indexable milling cutter for broad-spectrum applications.
