The Skymach CK6180 Heavy-Duty Flat Bed CNC Lathe Machine is engineered for heavy metal cutting, featuring a monoblock cast iron bed with 600 mm extra-wide induction-hardened guideways (HRC50). With an impressive 800 mm max swing over bed, a 480 mm max swing over carriage, an A2-11 spindle with Φ100 mm bore, and a mechanical 3-speed gearbox (40 - 950 RPM), the CK6180 delivers massive torque for turning large shafts, heavy flanges, valves, and mining machinery parts.
Outstanding Heavy Turning Features
- Rigid Monoblock Cast Bed: One-piece casting with 600 mm guideway width provides exceptional structural rigidity, superior vibration damping, and smooth chip evacuation.
- High-Torque A2-11 Spindle: The 100 mm through-hole bore accepts large bars up to 98 mm diameter, coupled with a 3-step gearbox for heavy roughing and precision finishing.
- Heavy-Duty MT6 Tailstock: Built with a Φ120 mm quill diameter and 250 mm travel to ensure maximum centering stability when machining heavy shafts between centers up to 3,000 mm.
Precision Control & Reliability
- Direct AC Servo Drive: Both X and Z axes feature direct-coupled AC servo motors and high-precision ground ballscrews (3205 on X-axis, 6310 on Z-axis).
- Comprehensive Protection: Fully enclosed ergonomic enclosure with high-visibility sliding operator doors, integrated chip troughs, and automatic lubrication.
