YAMA SEIKI GOODWAY GS-200 HORIZONTAL MACHINING CENTER

Technical Description

The YAMA SEIKI GOODWAY GS-200 Horizontal Machining Center is a high-performance CNC lathe designed for precision turning and multi-task machining. It features a main spindle with a maximum turning diameter of 15.75 inches and turning length of 23.27 inches, supported by an 8.07-inch chuck diameter and a maximum swing of 26.37 inches. The main spindle delivers 20 HP with speeds up to 4,800 RPM, while the sub-spindle offers 10 HP and reaches 6,000 RPM with a 6-inch chuck, enabling efficient back-end machining. The machine incorporates a 12-station servo indexing turret, capable of handling up to 12 turning and 12 rotary tools, with live tooling support at 4,000 RPM and 6 HP for milling, drilling, and tapping operations. The GS-200 offers precise 3-axis control with travels of 9.05 inches (X-axis), 23.62 inches (Z-axis), and an optional Y-axis travel of ±2.16 inches to enable complex machining tasks such as off-center drilling and grooving. Rapid traverse rates reach 788 inches per minute across all axes, supported by hardened and ground box ways for maximum rigidity and smooth movement. The machine's αP series spindle motor provides full horsepower at half the RPM of standard motors, increasing torque and cutting efficiency. Its built-in programmable tailstock and self-centering steady rest enhance workpiece support for stable, high-precision operations. The 30° slant bed design and robust construction ensure superior dynamic accuracy and surface finish, even under heavy cutting loads. Suitable for demanding turning applications, the GS-200 integrates turning, milling, and drilling capabilities into one versatile platform, making it ideal for complex production environments.
