New Possibilities in Machining

EMUGE-FRANKEN Circle Segment end mills vastly reduce finish-milling times for workpieces featuring TOUGH geometric contours.

These tools are primarily used in mold-making as well as in the production of tire molds, turbine blades, impeller blades, or blisks. Circle Segment end mills can optimize any 5-axis milling application with reduced cycle times and improved surface finishes.

EXPERIENCE A WHOLE NEW CLASS OF TOOLS

What makes these end mills unique is the large radii in the cutting area of the respective tool which offer entirely new possibilities in machining. The large radius simulates a ball-nose end mill with a cutting diameter of 12 to 3000 mm and even larger on request.

How does it work?

EMUGE-FRANKEN tooling design engineers worked closely with the industry leaders in CAM software to develop milling cutters that would optimize the performance of their software’s capabilities to produce complex shapes with superior surface finishes. By combining advanced cutting-edge geometries with exaggerated radius profiles, Circle Segment end mills mimic large diameter cutter profiles with standard tooling sizes. For example, a 16 mm diameter end mill can produce a 500 mm radius profile in one pass. This significantly increases the step over width of the end mill and reduces the milling cycle time by up to 90%.

Reduce Cycle Time and Improve Surface Finish

The ability to increase step over width drives down cycle time and improve surface finishes. Turbine blade milling results that were unachievable in the past are now being realized with this new technology.
