UB1800C Swivel Head 5-Axis Machining Center with C-Axis Rotary Table
The EUMASEIKI UB1800C is a travelling column swivel head 5-axis CNC machining center designed for maximum flexibility and versatility. It features an integrated C-axis rotary table, allowing the extra table space to be used for secondary operations or 3-axis work. With a maximum reach of 2000mm in the X-axis, 900mm in the Y-axis, and 800mm in the Z-axis, this machine can handle a wide range of sizes and shapes in various materials. The powerful B-axis milling head combined with the C-axis enables true 5-axis simultaneous machining, delivering high-speed cutting with excellent surface finish. Ideal for production in aerospace, energy, automotive, and other demanding sectors.
Key Selling Points
- Large Travel Range: X-axis travel of 1800mm and table size of 2000x900mm accommodate large workpieces, while the 900mm Y-axis overhang and 800mm Z-axis stroke provide flexible machining depth.
- High-Speed Spindle: 12000 rpm HSK-A63 spindle with 25.1/33.9 kW power (S1/S6-40%) delivers efficient cutting for both light and heavy applications.
- Precision Rotary Axes: B-axis tilt range of -120° to +120° with 0.001° minimum indexing, and C-axis 360° rotation via DD motor, ensuring precise complex contouring.
- Heavy-Duty Worktable: Fixed rectangular table supports up to 2000kg, while the C-axis rotary table carries up to 1800kg, ideal for large parts.
- Robust Tool Management: 40-tool magazine with 5-second tool-to-tool change minimizes downtime and supports continuous production.
- German Accuracy Standard: Position accuracy of 0.015mm (X/Y/Z) and repeatability of 0.008mm verified per VDI 3441, ensuring consistent part quality.
