Emuge Corp.’s Trochoidal line of solid carbide end mills with unique geometry and chip breakers are designed specifically for trochoidal milling. They provide increased metal removal rates (MRR) of over 30 percent, fewer tool paths and longer tool life, while enabling a high axial depth of cut of up to 4XD, the company says.

The Trochoidal end mills feature low vibration characteristics such as variable spacing, variable helix angles and improved micro-geometries, along with high-performance coatings of TiN/TiALN or ALCR and a sub-micro grain carbide substrate. According to the company, the chip breaker geometry reduces axial pull-out force and minimizes the risk of chip buildup in pockets, since the resulting smaller chips can be 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 range of materials.

    With the switch from a ground top-notch tool to a pressed Ingersoll threading form tool on one high-volume job, Warren Screw Machine eliminated 2 minutes of hand deburring per part. Not incidentally,  the company also lopped 20 seconds per part off the threading cycle.

  • Broaching On A Lathe

    Producing a keyway, spline or similar longitudinal feature on a turned part usually necessitates an additional, time-consuming, secondary operation on a broaching or slotting machine. That means moving the part to and from a secondary operation, an extra setup, additional labor and hourly machine costs and all of the other headaches that go with secondary operations.
