MMS AUGUST 2018 170 IMTS 2018 Turning Centers Vertical Turning Center Built for Making Gear Wheels Emag's VL 3 Duo is a twin-spindle, vertical pick-up turning center used for large-scale production of gear wheels and other gearbox components. The machine is designed for compactness and productivity, and has a footprint of 13 m 2 (140 ft 2 ). It accommodates parts rang- ing to 150 mm (2") in diameter. The VL 3 Duo can be fitted with the company's TrackMotion automation system, which consists of a track, the company's TransLift NC gripper that runs on the track and a raw-parts storage unit. The system installs directly behind the machining areas of the turn- ing center. The machine has a parts buffer and a pick-up spindle in each machining area. The automation system loads the individual part pallets on the parts buffer as they shuttle between the loading position near the machining area and the rear section of the machine. From there, the working spindle takes the raw part, transports it into the relevant machining area and places the part back onto the appropriate pallet after it has been machined. Immediately next to it, the subsequent part is waiting to be picked up by the spindle, so that only a few seconds pass until the next part is being machined. Each machining area has its own working spindle with a power rating of up to 18.1 kW and torque of up to 142 Nm. In addition, each machining area has a tool turret with 12 tool positions that can be fitted with turning tools or driven tools and fitted with an additional Y axis. | Emag LLC | South, Level 3, Booth 339436 Swiss-Type Lathe's Double-Gang Layout Shortens Cycle Times Marubeni Citizen-Cincom's D25 Swiss-type lathe fea- tures double-gang tool posts and a B axis. The double gang layout is said to shorten cycle times for high productivity. The machine can be equipped with up to 59 tools for the main spindle and subspindle to enable efficient production of complex workpieces. It also features independent, adjustable-angle rotary tools for the sub- spindle (three for the Y axis and three for the Z axis); a B axis for front-back machining; switchable operation for use with or without a guide bushing; a CNC with touch- screen; and a variety of interface choices. At the show, the company will also display additional equipment including machines, automation, bar feeders, laser welding and more. | Marubeni Citizen-Cincom Inc. | South, Level 3, Booth 339419
