YAMA SEIKI GOODWAY GTS-260 HORIZONTAL MACHINING CENTER

Technical Description

The YAMA SEIKI GOODWAY GTS-260 is a high-performance horizontal machining center featuring dual main spindles, each supporting a maximum turning diameter of 11.0" and a turning length of 7.87". Both spindles operate at speeds up to 4,000 RPM with 20 HP motors, capable of handling bar diameters up to 2.56". The twin-spindle design enables simultaneous front and rear machining, optimizing production efficiency in a compact footprint. It is equipped with two 12-station servo-driven turrets, each supporting up to 12 turning and 6 rotary (live) tools, with rotary tools rated at 0.62 HP and 4,000 RPM, allowing complex multi-axis operations. The machine features 6-axis control with rapid traverse rates of 787 inches per minute on the X, Y, and Z axes, and axis travels of 7.48" (X), 10.63" (Z), and includes Y-axis functionality for advanced milling and drilling. Structural rigidity is ensured through a heat-treated, precision-ground box way design combined with a 45° slant bed for low gravity and reduced wear. The CNC control supports simultaneous dual-tool cutting, enabling "done-in-one" machining processes. This results in enhanced accuracy, reduced setup time, and efficient handling of complex parts. The GTS-260 integrates powerful C-axis capabilities and optional Y-axis control, providing versatility for off-center milling, drilling, and tapping operations. Overall, the GOODWAY GTS-260 is engineered for robust, high-precision, multi-task turning and milling on large and complex components.
