Four Guideway CNC Lathe

The Four Guideway CNC Lathe is engineered for high-precision, heavy-duty machining of extra-large industrial components. Featuring an ultra-wide bed design, its four-guideway support system drastically reduces structural deflection, dampens cutting vibration, and ensures continuous machining accuracy under high torque loads up to 20 tons.

High Load Capacity for Oversized Parts: Engineered to handle massive workpieces without bed bending or axis misalignment.

Stable Machining under Dynamic Loads: Smooth cutting conditions during roughing of high-strength materials (carbon steel, alloy steel, stainless steel, cast iron).

Built for 24/7 Industrial Duty: Thermal-stable design and continuous automatic lubrication allow uninterrupted round-the-clock factory operation.

Oil & Gas Equipment: Large valve bodies, pipeline flanges, casing pipes, subsea drill collars.
Energy Equipment: Hydro/steam turbine shafts, generator rotors, nuclear power fittings.
Shipbuilding: Propeller shafts, rudder stocks, marine propulsion sleeves.
Mining & Heavy Machinery: Heavy drive shafts, crane drums, crusher main spindles.

Large Diameter Turning: Flanges, discs, valve bodies, and large sleeves.
Heavy Material Removal Rate (MRR): Rapid roughing of forged steel shafts and heavy castings.
Long Shaft & Pipe Turning: Extended bed designs with steady rests for marine shafts and hydraulic cylinders.
Heavy Load Capacity: Machining parts exceeding 5 to 20 tons without structural flex.

Heavy-Duty Cast Bed: Thermal-stress relieved casting with high shock-absorption properties.
Hardened & Ground Guideways: Guideway hardness reached HRC 52+ via frequency induction hardening, precision ground for minimum wear.
High-Precision Ballscrews: Large-diameter preloaded ballscrews coupled directly to servo motors for reliable positional accuracy.

Extra-Large Spindle Bore: Up to 500 mm bore for long pipe-end machining.
Hydraulic / Servo Turrets: Fast tool change speeds with live tooling options for milling/drilling.
Hydraulic Heavy Tailstock: Motorized quill positioning with continuous thrust clamping for long shafts.
Closed/Open Steady Rests: Roller-type heavy-duty steady rests for supporting workpieces up to 20 tons.
Automation & Measuring Tools: Automatic chip conveyors, Renishaw workpiece/tool setters, and coolant high-pressure systems.

Casting Integrity: Ultrasonic flaw detection and thermal stress relief before machining.
Guideway Precision: Laser interferometer measurement for bed straightness and parallelism.
Dynamic Balancing: Spindle assembly dynamic balance testing to minimize high-speed runout.
Laser Positioning Test: Full-length laser calibration for pitch error compensation.
48-Hour Dry Run & Trial Cutting: Full-load continuous cutting trial on workpiece samples prior to factory sign-off.

Packaging & Logistics: Anti-rust coating, vacuum-sealed barrier wrapping, and heavy-duty steel skid mounting for safe ocean transport.
On-Site Commissioning: Field service engineers available worldwide for installation, foundation setup, and operator training.
Parts & Technical Response: 12-month complete warranty, lifetime technical support, and critical wear parts dispatched within 48 hours via global express.
