Heavy Duty Vertical CNC Lathe

Designed for large-diameter and heavy workpieces, this Heavy Duty Vertical CNC Lathe combines high table load capacity, substantial cutting torque, and exceptional structural rigidity.

Loading workpieces directly onto the rotating table simplifies the setup of large, compact, or asymmetrical components that are difficult to mount on horizontal lathes. The double-column frame supports the crossrail from both sides, providing a massive machining envelope designed for heavy roughing and precision finishing.

Compared to single-column (cantilever) machines, the double-column frame provides superior rigidity under heavy cutting loads:
Balanced Force Distribution: Symmetric load paths eliminate column twisting during high-feed turning.
Stress-Relieved Castings: Bed, columns, and crossrail are cast from high-density Meehanite iron, subjected to thermal annealing and natural aging to guarantee long-term alignment stability.
Hardened & Ground Guideways: Wide box ways paired with Turcite-B anti-friction lining deliver maximum vibration damping and smooth feed motion.

Power Generation: Wind turbine components, generator rotors, turbine casings.
Mining & Heavy Equipment: Large drive wheels, crusher frames, winch drums.
Oil & Gas: Wellhead components, large subsea valve bodies, pipe connectors.
Metallurgy: Mill rollers, slag pots, heavy gear rings.

Double Columns: Form the rigid portal frame; anchored directly to heavy foundation beds for maximum dampening.
Crossrail System: Features hydraulic clamping mechanism at multiple points to lock rigid during heavy machining passes.
Precision Worktable: Supported by high-precision hydrostatic bearings or heavy-duty dual-row roller bearings, delivering high radial and axial stiffness.
Heavy Ram Assembly: High-grade forged steel ram with large cross-section ensures high rigidity during deep boring operations.
Precision Feed & Servo Drives: Pre-loaded AC digital servo motors combined with precision ball screws deliver accurate axis motion.
CNC & Electrical Cabinet: Thermally regulated enclosure housing premium components with international CE/UL compliance.

Supported processes completed in single or minimal setups:
External Turning & Facing: Large flange faces, steps, and outer diameters.
Internal Boring & Tapering: Deep cylindrical bores, internal steps, and programmed tapers.
Grooving & Threading: O-ring grooves, sealing faces, and standard/special threads.
Profiling & Chamfering: Complex contours via 2-axis CNC interpolation.

Tool Management: Manual tool post, 8/12-station automatic tool changer, or live tooling heads (C-axis).
Auxiliary Equipment: High-pressure coolant pumps, automatic chip conveyors, enclosed splash guarding, tool setters.
Electrical Standards: Customized voltage inputs (380V/480V, 50/60Hz) adhering to local code requirements.

Precision Alignment: Axis travel and pitch error verified using Renishaw Laser Interferometers.
Dynamic Testing: Ballbar circularity checks perform multi-axis motion verification prior to factory acceptance testing.
Standards Compliance: Built and tested in accordance with ISO 2831 precision standards and CE safety regulations.

Fully rust-protected, vacuum-sealed, and packed in heavy-duty ocean export wooden cases or flat-rack containers.
Complete lifting layout, loading weight distribution, and foundation engineering drawings provided before dispatch.
On-site foundation layout guidance, mechanical assembly, commissioning, and operator training conducted by senior technical engineers.
