The UV400 is a 5-axis CNC trunnion table machining center designed for complex part machining with high precision. Its worktable size is Ø400 mm, supporting up to 100 kg load. The A-axis tilts from -110° to +110° and C-axis rotates 360°, enabling simultaneous 5-axis machining. The machine is equipped with a 12000 rpm ISO 40 spindle and a 24-tool arm-type automatic tool changer. This model provides a compact footprint of 2700 x 4000 mm, making it suitable for high-precision manufacturing environments.
Key Selling Points
5-axis simultaneous machining: A-axis tilting range -110° to +110° and C-axis 360° rotation from the original spec, enabling complex contouring in one setup, reducing cycle times and improving accuracy.
High-speed spindle: 12000 rpm ISO 40 spindle from the spec, with power 11/20 kW (S1/S6-40%), ensures efficient cutting of various materials, from aluminum to steel.
Precision positioning: X/Y/Z positioning accuracy 0.007 mm and repeatability 0.005 mm per VDI 3441, with rotary axes division accuracy ±10 sec., guaranteeing high-precision output.
Fast tool change: 24-pocket arm-type magazine with tool-to-tool change time 1.5 seconds from the original, minimizing non-cutting time and boosting productivity.
Mineral cast iron structure: Based on company profile, machine bed uses mineral castings (available in options) with finite element analysis and full annealing treatment, ensuring thermal stability and vibration damping.
Reliable control: SYNTEC 220MA-5 numerical control system from the spec, user-friendly interface for efficient programming and operation.
