The Skymach CK61160 Heavy-Duty Flat Bed CNC Horizontal Lathe is built on an ultra-wide 1,100 mm monolithic induction-hardened cast iron bed, engineered specifically for large-diameter, extra-heavy workpiece turning. Featuring a massive Φ1600 mm swing over bed, a 22 kW 6-pole high-torque motor, an ISO A2-15 spindle nose with Φ130 mm through-bore, a 100/16 heavy-duty Z-axis ball screw, and an electric-driven motorized tailstock, the CK61160 delivers maximum metal removal rates and high contouring precision for heavy industrial machining.
Comprehensive Machining Capabilities
- 1,100 mm Ultra-Wide Heavy Monolithic Bed: Unrivaled structural rigidity and high dynamic mass absorb heavy cutting impacts during interrupted rough turning of large forgings and castings.
- Massive Spindle Torque: 22 kW 6-pole motor paired with a 4-step gearbox and external oil shower lubrication produces enormous low-end torque for large diameter turning.
- 100 mm Diameter Z-Axis Ball Screw: Nanjing Technology 100/16 ball screw driven by a 30 N.m servo with a 1:5 planetary reducer ensures effortless feeding of heavy tool slides.
Key Engineering Highlights
- Heavy Tailstock System: Features a massive Φ240/Φ265 mm quill with Metric 100/80 taper and motorized electric carriage drive for fast setup.
- High Working Capacity: Handles lengths from 1,500 mm up to 8,000 mm (customizable to 20,000 mm) with steady rests up to Φ800 mm.
- IT6-IT7 Long-Term Precision: Hardened slideways and high-grade bearings ensure surface finish Ra 1.6 μm and strict dimensional repeatability.
