The specific technical features of these end mills are the large radii in the cutting area of the tools. Their geometry represents a part of a circle, a circle segment. The large radius simulates a ball-nose end mill with a cutting diameter of 12 to 3.000 mm. As a result, the axial depth of cut can be enlarged and simultaneous the surface quality will be improved. Due to enlarged axial depth of cut, the machining time for prefinishing and finishing operations on five-axis-machining centres will be reduced significantly.
These tools are primarily used in mould-making as well as in production of turbine blades or blisks. To cover various applications, these end mills are available in four different basic shapes: Barrel-shape, Oval form, Taper form and Lens-shape. All basic shapes are available in different diameters and lengths.
An important role plays the CAM-System, which has to support and compute the geometry of the circle segment end mills. The CAM-System hyperMill of Open Mind offers the ideal milling cycle for each Circle Segment End Mill.
