2007 KITAMURA MYTRUNNION 5 VERTICAL MACHINING CENTER

Technical Description

The 2007 Kitamura Mytrunnion 5 is a 5-axis vertical machining center built around a large-format trunnion rotary tilting table capable of accommodating larger, heavier workpieces than the smaller Mytrunnion platform. The machine combines Kitamura's rigid Meehanite cast iron fixed-column structure with A-axis and C-axis integrated rotary motion, enabling complete 5-sided part access in a single setup. The worktable platter measures approximately 24.8 by 19.7 inches (630 x 500 mm), supporting workpieces through A-axis tilt and full 360-degree C-axis rotation. Linear axis travels span approximately 32.3 inches in X, 29.3 inches in Y, and 19.6 inches in Z. The high-frequency spindle reaches 20,000 RPM with approximately 17.5 HP (13 kW) continuous output through a CAT-40 taper, enabling high-speed 5-axis finishing in aluminum, titanium, and hardened steel. The Fanuc 16i-MB CNC control provides full 5-axis simultaneous interpolation, RTCP tilted workplane support, and look-ahead interpolation for smooth multi-axis surface generation. Precision ball screws and roller guideways on all linear axes ensure accurate, repeatable motion. An automatic tool changer with up to 50 stations supports complex multi-step 5-axis programs. The machine weighs approximately 38,000 lbs. The Mytrunnion 5 is well suited for large aerospace components, marine propellers, large impellers, and complex mold cavities requiring 5-axis contouring in a robust, high-payload platform.
