CK6140 Precision CNC Lathe: Cost-Effective Turning for High-Mix Production

Engineered for Flexible Job Shops

The CK6140 redefines entry-level CNC productivity with its hardened box-way construction and Fanuc 0i-TF control, delivering ±0.005mm repeatability at 35% lower TCO than European counterparts. Ideal for automotive bushings, hydraulic cylinders, and ISO-certified contract manufacturing.

5 Competitive Advantages

1. Rigidity-Price Breakthrough

Double-Wall Bed Design: 30% higher damping than linear guide lathes (vibration <3μm @1500rpm)
Integrated Coolant Tank: 120L capacity reduces refill frequency by 60%

2. Intelligent Operation

Feature	Impact
1-Key Thread Cycling	M24×1.5 threads in 18s (vs 45s manual)
Tool Eye Sensor	Automatic tool offset in 7s
Collision Guard	Halts within 0.2s if load spikes >120%

3. Expandable Configurations

Live Tooling Option: C-axis + 6-station milling for cross-drilling/keyway cutting
Bar Feeder Ready: 52mm spindle bore handles Ø50mm 6061 bars

4. Energy-Smart Architecture

Regenerative Braking: Recaptures 75% Z-axis deceleration energy
ECO Mode: Standby consumption 0.8kW (EN 50598 certified)

5. Zero-Downtime Engineering

Centralized Lubrication: 23-point auto-greasing every 4 hours
QR-Code Manuals: AR-guided troubleshooting via smartphone
