Overview
The CK5225D double-column vertical lathe redefines heavy-part precision with its 2500mm cutting diameter and 10-ton load capacity. Powered by Siemens 828D CNC (FANUC/GSK optional) and a 55kW AC motor with two-stage gearbox, this beast delivers 63kN·m torque at 2-63 RPM-crushing S355JR steel at 35kN cutting forces. With thermo-stabilized hydraulics (±1°C oil temp control) and W-Cr-Mn alloy guideways, it maintains IT6 tolerances during 24/7 operation for offshore wind and nuclear applications.
Core Applications
Offshore Wind Flanges
Machine 2.5m EN10025 flanges with ±0.08mm flatness. The 1400mm horizontal travel + CSCS function maintain 150m/min surface speed-proven 42% faster than single-column VTLs in North Sea projects .
Nuclear Valve Bodies
Face-cut Inconel 718 seats at 8 RPM. Right tool post's 35kN force + constant-flow lubrication achieve Ra 0.8μm finishes under thermal shock .
Hydro Turbine Shafts
Turn 1600mm ZG270-500 shafts in one setup. Dual-column rigidity absorbs 12kN vibrations during interrupted cuts-Swiss hydropower plants report 98% first-pass yield .
Engineering Breakthroughs
Thermal Warfare: Refrigerated hydraulic station (±1°C) + pre-tensioned ballscrews limit thermal drift to 3μm/m after 12hrs (FEA-verified) .
Zero-Downtime Transmission: Grade 1 planetary reducers + ISO 1328-1 Class 6 gears reduce noise to 65dB at full load .
Smart Guarding: W-Cr-Mn alloy guideways under full covers prevent 95% swarf damage in foundry environments .

ROI Case Study
At $128,000 (FOB China), pays back in 11 months:
| Metric | Single-Column VTL | CK5225D | Improvement |
|---|---|---|---|
| Valve Body Cycle | 14.5 hrs | 8.4 hrs | ↓42% |
| Hydraulic Failure | 3/yr | 0.2/yr | ↓93% |
| Energy Consumption | 82 kWh/day | 58 kWh/day | ↓29% |
Pro Tip
Activate CSCS mode when tapering >30° cones-auto-maintains 150m/min surface speed. Monthly hydraulic oil particle count checks prevent 90% pump failures.
