OKUMA will launch the VTR-160A, a gate machining center with a maximum diameter of 1.6m. Based on the gate machining center, high rigidity is achieved. Furthermore, the accuracy is improved by suppressing thermal deformation. The "VTR-200A" with a maximum machining diameter of 2m, the "VTR-250A" with a maximum machining diameter of 2.5m, and the "VTR-350A" with a maximum machining diameter of 3.5m are scheduled to be released as the "VTR-A" series. The interior of the main large part of the base and the column are made of a highly rigid diagonal rib structure. A 250 x 250 mm ram is also used. Even if the ram feeds 600mm, it can be turned to 10mm2 (S45C). The rotary tool spindle has a built-in motor design that reduces motor vibration and improves rotation accuracy. In the turning process, the tool is strongly clamped by using a coupling with a diameter of 200 mm, so that heavy-duty cutting can be performed. The turning spindle uses large-diameter roller bearings and thrust bearings to stably support large workpieces. The VTR-160A can carry 10t workpieces. A "Thermo Friendly Concept" technology that prevents dimensional changes in processing due to thermal deformation during long-term processing is employed. Even if the room temperature changes by 8 ° C, the thermal deformation in the X-axis direction during long-time processing can be controlled to 20 μm or less.
