YAMA SEIKI GOODWAY GS-4000 HORIZONTAL MACHINING CENTER

Technical Description

The YAMA SEIKI GOODWAY GS-4000 is a heavy-duty CNC horizontal turning center designed for maximum performance machining operations. Featuring a 37 kW (50 HP) spindle motor with 2-speed gearbox capability reaching 2,000 RPM, this machine accommodates workpieces up to 24.4 inches in diameter and 93.26 inches in turning length. The 18-inch chuck and Ø4.5-inch bar capacity provide versatility for both bar and chuck operations. The machine is equipped with a 12-station servo-indexed turret offering exceptional rigidity and tool capacity. Advanced features include an optional sub-spindle powered by an 18.5 kW motor reaching 4,800 RPM with 8-inch chuck for efficient back-end machining and automatic parts ejection. Live tooling capabilities are driven by a 7.5 kW spindle motor, enabling multi-directional cutting operations. The C-axis features FANUC spindle motor control with 0.001° minimum indexing angle for complex contoured machining. The machine provides rapid X, Y, and Z-axis movement up to 945 IPM with 189 IPM maximum feed rates. Standard features include programmable tailstock, automatic self-centering steady rest, chip conveyor, and Y-axis control (±60 mm travel) for enhanced machining complexity. Optional configurations support up to 3 simultaneous axes with varying bed lengths from 32 to 125 inches, accommodating diverse production requirements from bar and chucker work to universal machining applications.
