5-AXIS BRIDGE-TYPE MACHINING CENTRE
Exceptional precision,
built for scale.
The UNIKA Series is a high-performance 5-axis bridge-type machining centre engineered for the precision machining of large and complex components. Rigid bridge construction, high-speed simultaneous 5-axis capability and advanced spindle technology deliver accuracy, reliability and productivity across aerospace, automotive, energy, die & mould and general engineering.
Built on over four decades of machine-tool manufacturing expertise, every structural element is optimized with Finite Element Analysis (FEA) to maximize rigidity, minimize vibration and protect long-term machining stability.
ENGINEERING DEEP DIVE
Rigidity in every
moving axis.
Outstanding Structural Design
Every major structural component is analyzed and refined with FEA for maximum stiffness in static and dynamic machining conditions. The result is accurate cutting, excellent vibration damping and reliable long-term performance.
KEY BENEFITS
- Maximum stiffness and damping for stable precision machining.
- Reduced thermal distortion during heavy-duty cutting.
- Smooth, vibration-free motion across the full working envelope.
High-Rigidity Bridge Construction
A reinforced bridge and column reduce thermal distortion while supporting high metal-removal rates and excellent surface finishes.
Cross-Roller Linear Guideways
Multiple bearing blocks on X, Y and Z deliver high rigidity, positioning accuracy, dynamic load capacity and extended service life.
High-Performance 5-Axis Milling Head
A direct-drive dual-axis milling head uses high-torque DD motors for continuous, high-precision B/C-axis performance.
KEY BENEFITS
- Full simultaneous 5-axis machining with zero-backlash rotary axes.
- Hydraulic clamping for rigidity during heavy cutting.
- Continuously calibrated B/C axes maintain tool-tip accuracy on complex free-form surfaces.
Direct-Drive Rotary Axes
High-speed continuous B/C-axis interpolation, high-precision encoder feedback and RTCP compensation support complex geometry.
Heavy-Cutting Stability
Hydraulic clamping provides maximum rigidity whenever the application calls for high cutting loads.
Through-Spindle Coolant
CTS is available to improve chip evacuation and cutting performance in demanding materials.
Precision Motion System
UNIKA maintains exceptional positioning accuracy throughout the full working envelope with a motion system designed for rigidity and repeatability.
KEY BENEFITS
- Full-travel Z-axis support and four-guideway ram rigidity.
- Direct-coupled servo drives with high-resolution feedback.
- Automatic lubrication for reliable long-term operation.
Four-Guideway Z-Axis Ram
High-rigidity guidance and extended Z-axis support keep the ram stable over its full travel.
High-Precision Drive System
Ballscrews, direct-coupled servos and rotary feedback provide accurate, repeatable positioning.
Protected Accuracy
Automatic lubrication helps preserve motion quality, component life and productivity.
Intelligent Machine Design
Operator convenience and production efficiency are built into the UNIKA working environment.
KEY BENEFITS
- Comfortable access for setup, loading and maintenance.
- Stable prolonged production with rapid chip removal.
Ergonomic Access
A user-friendly swing-arm control panel, foldable safety doors and spacious working area simplify operation and maintenance.
Dual Chip Conveyors
Twin conveyors rapidly remove chips to maintain stable machining conditions during prolonged production.
Spindle & Simultaneous 5-Axis Machining
The TTFE3 five-axis milling head uses a synchronous spindle motor for strong torque across its speed range, serving both roughing and high-speed finishing.
KEY BENEFITS
- Complex components completed in a single setup.
- Less handling, fewer operations and reduced cycle time.
- Better geometric accuracy, surface finish and machining flexibility.
