YAMA SEIKI GOODWAY GS-2000 HORIZONTAL MACHINING CENTER

Technical Description

The YAMA SEIKI GOODWAY GS-2000 Horizontal Machining Center is a high-precision CNC turning center designed for demanding machining tasks. It features a powerful main spindle with a maximum turning diameter of 18.11 inches and a maximum turning length of 31.49 inches, equipped with an 8-inch diameter chuck and 2-inch maximum bar capacity. The main spindle operates at up to 4,800 RPM delivering 25 HP, supported by a sub spindle running at 6,000 RPM with 10 HP, enabling efficient back-end machining. It integrates a 12-station servo indexing turret for primary tooling, supporting up to 12 turning and 12 rotary tools, with rotary tools running at 4,000 RPM and 6 HP, allowing versatile operations such as milling, drilling, and tapping. The machine operates on 3 axes (X, Y, Z) with travels of 11.02 inches (X), ±1.96 inches (Y-axis not explicitly stated but commonly around ±50 mm), and 31.49 inches (Z) respectively. It achieves high feed rates of 189 IPM and rapid traverses up to 1,180 IPM on all axes, enhancing machining speed and efficiency. The GS-2000 features a robust box way slide for rigidity and precision, and a low center-of-gravity 30° slant bed design to optimize structural strength. Its spindle drive system is belt-driven, equipped with P4 grade high-precision bearings and an optional oil cooler to manage thermal expansion, ensuring long-term machining accuracy. Overall, this turning center is engineered for high-rigidity, flexible tooling, and dynamic performance, ideal for complex, high-precision turning applications.
