End Mills Designed for Trochoidal Milling

June 30, 2017
Emuge Corp. has designed end mills specifically for trochoidal milling.

Trochoidal End Mills are solid carbide end mills with unique geometry and chip breakers designed specifically for trochoidal milling. They provide increased metal removal rates (MRR) of over 30%, fewer tool paths, and longer tool life while enabling a high axial depth of cut of up to 4XD.


They feature low vibration characteristics such as variable spacing, variable helix angles, improved micro-geometries, along with new high performance coatings of TiN/TiALN or ALCR and a sub-micro grain carbide substrate. In addition, the newly developed chip breaker geometry reduces axial pull-out force and minimizes the risk of chip build up in pockets, since the resulting smaller chips can be easily removed with compressed air or coolant.


Emuge Trochoidal End Mills are available in two cutting geometries: Jet-Cut for both roughing and finishing in steel applications, and Coolant-Through TiNox-Cut for process-reliable roughing in tough materials such as Inconel, Titanium, and Stainless Steel. Standard and long-length rougher/finishers with flute length/diameter ratios of 2:1, 3:1 and 4:1 are available for applications in a wide range of materials.


The Trochoidal end mill series was developed specifically for advanced milling strategies available in modern CAM software to optimize the calculation of milling paths and avoid unproductive tool motion.
