C5116 Single Column Vertical Lathe: Heavy-Disk Machining Economy Redefined

Engineered for Compact Heavy-Part Turning

The C5116 revolutionizes mid-size vertical turning with its space-efficient single-column design, delivering ±0.01mm accuracy on Ø1600mm workpieces while occupying 30% less floor space than double-column alternatives. Ideal for energy flange facing, marine gear blanks, and contract machining shops with ceiling height constraints.

5 Competitive Advantages

1. Rigidity-Space Optimization

Monoblock Column: Reinforced HT300 cast iron with 1:4.5 depth-width ratio resists 25KN cutting forces
Low-Profile Design: 3.2m height clears 3.5m workshop ceilings (vs 4.8m+ for double-column)

2. Precision Control Systems

Feature	Impact
Pre-Stretched Ballscrews	Eliminates thermal drift (±0.005mm/300mm)
Digital Readout	0.001mm resolution on cross/vertical slides
Turret Locking	12-ton clamping force for heavy interrupted cuts

3. Hybrid Operation Flexibility

Manual-CNC Freedom: Conventional handwheels + optional Siemens 808D ADV CNC
Quick-Change Tooling: VDI 40 interface swaps tools in <45s

4. Heavy-Cut Capability

50kW Spindle Motor: Removes 12mm depth-of-cut on 304 stainless at 32m/min
Central Coolant Flood: 80L/min flow clears chips from Ø1500mm surfaces

5. Zero-Foundation Installation

Self-Leveling Pads: Compensates ±3° floor inclination (ISO 8636-1)
Integrated Chip Conveyor: 2m³/hr capacity eliminates manual cleaning
