Large Vertical CNC Lathe

The Large Vertical CNC Lathe is engineered for precise, high-rigidity machining of heavy, large-diameter workpieces. Designed with a horizontal rotary table, the machine supports total component weight directly from below, ensuring maximum stability during heavy roughing and precision finishing.

Ideal for processing components with high weight-to-diameter ratios-such as large flanges, rings, discs, hubs, bearing housings, gear blanks, and heavy industrial castings.

Gravity-Supported Workpiece Mounting: The part sits directly on the horizontal table, eliminating spindle sag, deflection, and complex counterweighting common in horizontal lathes.
Top-Loading Accessibility: Open top architecture enables fast, safe loading using overhead workshop cranes.
Optimized Large-Face Machining: Direct face turning across large surface areas without altering part alignment or re-clamping.
High Structural Stability: Short distance between the table support bearings and foundation provides maximum dampening during heavy intermittent cuts.

Wind Power & Energy: Wind turbine hubs, slewing rings, generator housings, and tower flanges.
Mining & Construction Equipment: Crusher frames, heavy gear rings, wheel hubs, and excavator swivels.
Power Generation & Turbines: Steam/hydro turbine housings, large sealing rings, and heavy valve bodies.
Oil & Gas Industry: Subsea valve bodies, blowout preventers (BOP), and high-pressure flanges.
Metallurgy & Heavy Manufacturing: Rolling mill components, forged rings, and industrial furnace bases.

Symmetric Force Distribution: Twin columns support the crossbeam from opposite sides, channeling heavy cutting forces straight into the rigid machine base.
Stable Tool Support: High-rigidity cast frame dampens vibrations during aggressive cuts on cast iron and forged steel.
Expansive Working Space: The wide opening between columns accommodates bulky geometries while maintaining high structural stiffness.
Integrated Drive Systems: Frame, hydrostatic table, main drive, and RAM tool post are precision-matched to maximize cutting efficiency.

The machine performs diverse heavy-duty turning operations on a single setup:
External Turning (OD): Cylindrical surfaces, shoulders, steps, and outer contours on flanges, gear blanks, and housings.
Internal Boring (ID): Large-diameter internal bores, pump cavities, and bearing seats with extended ram reach.
Face Turning: High-precision flat facing on flange sealing surfaces, mounting pads, and disc faces.
Grooving & Tapering: Internal/external seal grooves, snap ring slots, and conical taper turning via multi-axis CNC interpolation.
Heavy stock removal (roughing) followed by fine tool passes (finishing) to meet tight dimensional tolerances and surface finishes.
 

Tailor machine build options to match specific production demands:
Rotary Table: Hydrostatic or precision roller bearings configured for high torque or higher RPM.
Tool Post & Ram: Single ram, dual ram, live tooling (milling/drilling), or automatic tool changers.
Main Drives & Motors: Heavy-duty two-speed gearboxes providing high torque at low speeds.
Auxiliaries: High-pressure coolant systems, automatic centralized lubrication, chip conveyors, and Renishaw tool/part probes.
 

Seaworthy Export Packaging: Rust-inhibitor coating, heavy plastic wrapping, and steel-skid wood crate framing.
Disassembly & Assembly Marking: Clear match-marking on structural sub-assemblies for seamless re-assembly.
Foundation & Site Readiness Plan: Complete foundation layout drawings and electrical planning provided prior to shipment.

On-Site Commissioning & Service: Global field technical support available for installation, commissioning, and operator training.
