Jim Walslager, Lead Programmer at RWD in Ringwood, IL is glad that he’s invested in Circle Segment cutters from high-performance cutting tool manufacturer, EMUGE-FRANKEN, of West Boylston, Mass. “Prior to this, my only alternative was to finish the conical surface with a ball-nose end mill. I didn’t even bother trying, but because the CAM system said it would have required close to five hours per part. The EMUGE cutter did it in 38 minutes.” He laughed. “The thing started out as a 100-lb. block of 6061-T6
The Jet-Cut series was uniquely developed for high-performance cutting (HPC) and high-speed cutting (HSC) applications. - 50˚ high helix flutes with vibration dampening variable flute spacing - Enlarged chip gash end geometry - PVD applied high-performance TIAlN coating - Radial chip forming geometry
The TiNox-Cut / Base series was specially developed for machining stainless steel. Unique flute design combined with tightly controlled cutting edge profile for stainless steel alloys which require higher shearing characteristics. With a proprietary PVD heat resistant coating, the Base series has been proven to be successful in even dry machining applications.
We are making test cuts using Emuge's Jet Cut 3/8" diameter end mill cutting at 1.5X D depth (.512" deep) in 4140 Pre Hardened steel on a Haas DM2 milling center. We are cutting 5 areas that are X dim 3.0" x Y dim .625". The tool path is Mastercam Dynamic Peel mill and the CNC machine is a Haas DM2. We are increasing the width of cut of each area along with adjusting the SFM and chip load. After each cut we captured several chips and viewed them under a microscope to analyze the color and shape.
