MITSUI SEIKI VERTEX 550-5X VERTICAL MACHINING CENTER

Technical Description

The MITSUI SEIKI Vertex 550-5X is a high-precision, five-axis vertical machining center designed for demanding aerospace, mold, and energy sector applications. It features a rigid "box-in-box" structure with a gear-driven trunnion tilt axis for enhanced stiffness and precision. The machine provides X, Y, and Z travel capacities of 21.65", 23.62", and 19.68" respectively, with an A-axis tilt range from +15° to -105° and a B-axis offering full 360° rotation at 0.001° resolution, allowing complex 5-axis contour machining. Its robust spindle delivers 24 hp at speeds up to 25,000 RPM with an HSK-A63 taper, supporting high-speed cutting with rapid traverse rates of 1,890 in/min on all linear axes. The rotary table diameter is 15.75", capable of holding workpieces up to 771.6 lb, with maximum workpiece dimensions of 29.5" diameter and 20.65" height. The machine integrates a 40-tool automatic tool changer (ATC) for enhanced productivity. Precision feedback is maintained via linear glass scales for linear axes and rotary scales for A and B axes, ensuring positioning accuracy of ±0.001 mm and angular accuracy in arc seconds. Additional factory options include spindle cooling, through spindle coolant, tool setting probes, and dynamic fixture offsets. The overall dimensions are 138" x 79" x 111", weighing approximately 20,943 lb, making it suitable for heavy-duty, precise five-axis machining operations demanding high rigidity and accuracy.
