YAMA SEIKI GOODWAY HA-1800 HORIZONTAL MACHINING CENTER

Technical Description

The YAMA SEIKI GOODWAY HA-1800 is a flat-bed horizontal turning center engineered for heavy-duty machining of large, extra-long workpieces in aerospace, energy, and shipbuilding industries. It features a maximum turning diameter of 66.920 inches and swing diameter of 78.740 inches, with a 24-inch chuck and capacity for 20-inch bar stock. The machine is powered by a single main spindle delivering 60 HP at 250 RPM, providing robust torque for demanding cutting operations on components requiring exceptional rigidity. The HA-1800 incorporates a high-rigidity four-box way cast iron bed with a one-piece headstock weighing over 4,000 kg, ensuring superior vibration damping and precision during heavy cutting. Its 12-station turret accommodates both traditional and live tooling options, with rotary tool capability reaching 4,000 RPM at 15 HP, enabling multi-axis machining including turning, milling, and drilling operations. The machine provides rapid traverse rates of 394 IPM across X, Y, and Z axes, with X-axis travel of 35.230 inches and configurable Z-axis travel up to 202.750 inches for extended workpiece lengths. Standard two-axis configuration is expandable to three-axis with optional C-axis control, featuring programmable servo-indexed positioning with ultra-high resolution capability. The machine operates on FANUC Oi-TD CNC control and utilizes a programmable tailstock with rotary quill for enhanced flexibility in complex part production.
