Five-Axis Line Targets Die/Mold, Aerospace
With so much happening in a busy show year between NPE2018 and Amerimold 2018, MoldMaking Technology is revisiting some of the technology that was on display. In case you missed it: At IMTS 2018, Takumi USA displays its series of five-axis machining centers, which includes the U600 model and the U800 model.
Takumi USA’s series of five-axis machining centers includes the U600 model (XYZ/AC Travels: 24.4" × 39.4" × 19.7"/+30°-110° × 360°) and the U800 model (XYZ/AC Travels: 31.5" × 39.3" × 29.5"/±120° × 360°). Both machines utilize a trunnion-style, two-axis table and the Heidenhain TNC 640 control. The machines are designed for die/mold, aerospace and high-speed applications that require tight tolerances.
The U800 isa gantry machining center with a high-torque table (800 mm platter) with an 80-rpm, twin-torque motor in the A axis and a 100-rpm, single-torque motor in the C axis. It will be shown cutting a 20" tall, 4140 steel replica of the famous Venus De Milo sculpture to showcase its rigidity, speed and surface finish capability.
A provider of machine shop training offers these questions for benchmarking metalworking knowledge.
With many 3D milling applications demanding both shorter cycle times and smoother surface finishes, it’s time to review how you go about programming and machining parts. These four strategies will let you rough dramatically faster and achieve astonishingly fine surface finishes.
Different tools and machining strategies have driven this shop to seek new efficiencies beyond its most demanding work and most capable machining center.
