The Skymach CW61100 Heavy Duty Horizontal Conventional Lathe is a massive, high-power industrial turning machine engineered for heavy-duty metal removal on extra-large components, such as marine propulsion propeller shafts, hydro and steam turbine rotors, steel mill rolls, heavy forging billets, mining rollers, and large-diameter industrial flanges.
Boasting a 1600 mm maximum swing diameter over bed, an 1180 mm swing over cross slide, turning lengths up to 10,000 mm (customizable up to 20 meters), and a massive total machine mass ranging from 18.5 to 30.2 tons, the CW61100 delivers unmatched cutting torque, torsional rigidity, and geometric precision under extreme chip-removal workloads.
Outstanding Heavy-Duty Turning Capabilities
- Massive 1600 mm Swing Over Bed: Generous clearance allows turning of extra-large disc forgings, mill rings, locomotive axles, and flanged pipe assemblies.
- Customizable Bed Lengths Up to 20 Meters: Standard center distances from 1500 mm to 10000 mm, with tailor-made beds extendable to 20000 mm for super-long shaft machining.
- Φ130 mm Spindle Through-Bore: High-rigidity spindle accommodates through-hole bar feeding and pipe threading of large tubular workpieces.
- 22 kW High-Torque Drive: 6-pole heavy motor powers a 21-speed forward and 12-speed reverse geared headstock (2 - 200 RPM), delivering colossal low-speed cutting torque for tough alloy steels and forged components.
Rock-Solid Construction & Massive Components
- Monolithic Multi-Guideway Cast Iron Bed: Ultra-wide induction-hardened guideways absorb intense cutting forces and dampen vibration during aggressive roughing passes.
- Extended 800 mm Cross Slide Travel: Wide X-axis saddle movement accommodates deep stepped turning and large radial tool offsets, complete with a 3740 mm/min motorized rapid traverse.
- Giant Φ240 mm Tailstock Quill: Massive tailstock body features a Φ240 mm quill diameter with 300 mm travel, providing unyielding center support for workpieces weighing dozens of tons.
- Φ1250 mm 4-Jaw Independent Chuck: Provides secure clamping force and versatile centering capability for symmetrical, asymmetrical, and irregularly shaped heavy forgings.
