Large Horizontal CNC Lathe

The Heavy-Duty Large Horizontal CNC Lathe is engineered for manufacturers processing large shafts, rollers, hydraulic cylinders, heavy flanges, turbine rotors, and long pipe components.

With turning diameters up to 2500 mm, machining lengths up to 12000 mm, and heavy-load capacities up to 20 tons, this machine delivers structural rigidity, high spindle torque, and thermal stability for heavy-duty turning operations.

Reinforced Machine Structure
The machine bed is cast from high-grade Meehanite-style cast iron with densely arranged internal reinforcement ribs. This design maximizes vibration damping under heavy interrupted cuts, enhancing tool life and workpiece surface finish.

Large-Capacity Machining Capability
Featuring a wide swing over bed and customized distance between centers, the machine accommodates oversized forgings, long drive shafts, and large-bore pipes that exceed standard CNC lathe limits.

High-Torque Spindle Drive
Equipped with high-power motor options (up to 90 kW) and multi-range headstock gearing, the spindle delivers high torque at low speeds for deep roughing passes in tough alloy steels and cast iron.

Sustained Thermal & Dimensional Stability
Precision ball screws, forced lubrication systems, and heavy-duty box guideways maintain strict positioning accuracy during extended, multi-hour machining cycles.

Flexible Modular Configurations
Tailored to specific production needs with optional hydraulic steady rests, automatic tool turrets, tailstocks, chip conveyors, and automated loading interfaces.

Heavy Machinery & Mining: Crushing shafts, hydraulic excavator cylinders, and gear housing blanks.
Oil & Gas: Heavy-wall drill pipes, casing components, and pressure valves.
Shipbuilding: Marine propulsion shafts, stern tube bearings, and large flange fittings.
Wind Power & Energy: Turbine main shafts, generator shafts, and hydro-turbine components.
Steel & Metallurgy: Mill rolls, continuous casting rolls, and heavy forge blanks.
Railway & Transport: Locomotive wheelsets, axles, and drive shafts.
 

Meehanite Cast Iron Bed
Stress-relieved, high-density cast iron bed provides maximum torsional rigidity. The internal rib structure effectively absorbs dynamic stresses during heavy rough turning.

Extra-Wide Induction-Hardened Guideways
Induction-hardened to HRC 52+ and precision ground, the extra-wide slideways are lined with Turcite-B anti-wear material to eliminate stick-slip and maintain smooth carriage movement under full load.

Advanced Workpiece Support System
To prevent sagging and vibration on long shafts or heavy tubes, the machine supports open/closed hydraulic steady rests and follow rests with heavy-duty roller bearings.

Modern CNC control systems ensure process accuracy, ease of operation, and efficient program management:
Multi-Axis Synchronized Control: Precision movement along X and Z axes for complex contours, tapers, and threads.
Automatic Tool Compensation & Wear Monitoring: Maintains consistent dimensions over long production runs.
Built-in Diagnostics & Condition Monitoring: Real-time alarm handling, thermal compensation, and fault troubleshooting.

Spindle & Chuck: Front/rear dual chucks, large bore up to 320 mm, hydraulic or manual 4-jaw independent chucks.
Tooling Systems: 4-position heavy-duty vertical turret, 8/12-position hydraulic turret, or live tooling with C-axis capability for milling and drilling.
Supports & Accessories: Hydraulic steady rests (self-centering), roller steady rests, chip conveyors (hinged belt/scraper type), high-pressure coolant pump (up to 20 bar).
Automation: Automatic tool setters, workpiece measuring probes, and automated loading/unloading interfaces.

Every machine undergoes rigorous quality verification prior to dispatch:
Laser Calibration: Axis positioning and repeatability verified with Renishaw laser interferometers.
Spindle & Geometry Inspection: Dynamic spindle runout, bed levelling, and tailstock alignment testing.
Full-Load Trial Machining: Test-cutting on actual workpieces or sample materials according to client specifications.

Full technical documentation package: English operator manual, electrical schematics, foundation drawings, and spare parts catalog.
Warranty: 12 to 24-month comprehensive warranty on key structural and mechanical components.
Technical Support: Overseas engineer installation/commissioning, operator training, and 24/7 remote diagnostic support.
