Milling Titanium Ti6Al-4V with 8 cutting edges per insert!

Up to 8 cutting edges per insert. That’s helical milling at the lowest possible cost-per-edge. HARVI Ultra 8X helical milling cutters are designed to deliver the highest metal removal rates (MRR), especially in high-temperature alloys (Titanium).

GF Demonstrates AM Production and EDM Cut-Off Solutions at AMUGexpo 2020

At the 2020 AMUGexpo, exhibitor and Platinum Sponsor GF Machining Solutions will demonstrate its high-throughput DMP Flex 350 metal 3D printer and its new AgieCharmilles CUT AM 500 horizontal wire Electrical Discharge Machining (EDM) at the Hilton Chicago. These high-precision machines combine to create a complete automation-ready additive process that includes the ability to quickly and accurately separate parts from build plates without the use of a band saw.


The robust, flexible DMP Flex 350 enables efficient 24/7 production of very dense, pure metal parts from 11 ready-to-run challenging alloys, including thoroughly qualified Inconel, titanium, cobalt chrome, aluminum and steel. Improved gas flow technology produces more-uniform part quality throughout the build area. Short changeover times and streamlined 3DXpert® all-in-one parametric software speed the process from 3D model to successful part printing, with reduced assembly steps for better manufacturing efficiency and maximum uptime through well-developed and tested print settings.


The DMP Flex 350 uses a 500W laser to generate precise parts up to 10.82" x 10.82" x 16.54" (275 x 275 x 380 mm), with a minimum feature size of 100 μm and ± 0.1-0.2% accuracy with ± 50 μm minimum. With ≤25 ppm O₂ level in the build chamber, the DMP Flex 350 guarantees excellent microstructure density, stable mechanical properties and consistent powder quality for high-quality parts. Total cost of ownership remains low thanks to high powder recyclability, low consumables usage and a long-lasting process filter. For the ultimate in flexibility, the DMP Flex 350 upgrades to the DMP Factory 350, with integrated powder management system, high-performance sieving and automated powder conveyance.


To remove AM parts from their build plates, many solutions use conventional EDM or a band saw, with results that can offer less speed and accuracy than an efficient workflow requires. To meet these needs, the automation-ready AgieCharmilles CUT AM 500 reliably cuts AM parts that feature specific support structures and cavities with remaining AM powder. The machine’s tilting table, horizontal wire EDM configuration and customizable baskets maintain part integrity during the cut-off process. An optional clamping system integrates directly into the machine layout for easier referencing, while double-spool wire and dedicated cutting technology reduce running cost to as low as that of the band saw it replaces.


The AgieCharmilles CUT AM 500 handles width, depth and height dimensions up to 20.08" (510 mm) and weights up to 1,102.31 lbs. (500 kg) for base plate plus parts. Cut speed reaches 11.02 square inches per minute (280 mm2/min) with an accuracy of ± 0.0039" (± 0.1 mm) and a roughness (Ra) of <6 μm.
