MITSUI SEIKI HW550A HORIZONTAL MACHINING CENTER

Technical Description

The Mitsui Seiki HW550A is a robust horizontal machining center designed for high-precision and versatile manufacturing applications. It features a substantial X-axis travel of 29.53 inches, Y-axis travel of 31.5 inches, and Z-axis travel of 33.46 inches, enabling large workpiece accommodation and complex machining operations. The pallet measures 21.654 inches by 21.654 inches, optimized for efficient workpiece handling and quick changeovers. Operating with a 4-axis simultaneous control configuration, this machine allows precise linear and rotary interpolations suitable for a wide range of milling tasks. The machine’s CNC control utilizes the FANUC 31i system, a high-performance controller capable of managing up to 4 simultaneous axes with advanced digital servo control, nanometer resolution, and fast interpolation times for superior surface finish and accurate contouring. The FANUC 31i also supports features such as exact stop and helical interpolation, offering flexibility and enhanced machining quality. Weighing 35,273 lbs, the HW550A is constructed for stability and vibration damping, essential for maintaining tight tolerances during high-speed cutting. Integrated with sophisticated servo amplifiers and feedback systems, this machining center delivers consistent precision and reliability. It is suited for industries requiring complex, high-quality parts, including aerospace, automotive, and mold making. The combination of Mitsui Seiki's mechanical robustness and FANUC's advanced CNC control makes the HW550A an ideal solution for demanding milling applications with a focus on accuracy, productivity, and operational flexibility.
