Heavy Duty Conventional VTL Two Column -5263

Product Overview

The Heavy Duty Conventional VTL Two Column 5263 is a rugged vertical turning lathe engineered explicitly for large-scale machining of ultra-heavy workpieces. Its double-column structure—forged from high-grade HT300 cast iron—delivers superior rigidity, enabling it to handle diameters up to 6300mm and workpiece weights reaching 40,000kg without deflection. Designed for manual operation, it offers unparalleled flexibility for one-off prototyping and low-volume production of oversized components. The machine incorporates hydrostatic guide rails that reduce friction by 70% compared to traditional sliding rails, while its cast iron bed undergoes twice aging treatment (6 months natural aging + artificial aging) to eliminate internal stress, ensuring dimensional stability over decades of heavy use.

Applications

Shipbuilding: Machining propeller hubs (up to φ5000mm), engine foundations with flatness requirements of 0.05mm/m, and stern tube housings for marine engines.

Power Generation: Fabricating nuclear reactor pressure vessels (wall thickness up to 300mm) and steam turbine casings with complex internal cavities.

Heavy Fabrication: Producing large gears (module up to 50mm), pressure vessels for chemical industries, and structural steel parts for bridge construction.

Its versatility spans ferrous metals (carbon steel, alloy steel), non-ferrous alloys (titanium, copper), and even fiber-reinforced composites, making it indispensable for industries requiring heavy-duty manual machining control.

FAQ

Q: Can the Two Column 5263 be upgraded to CNC in the future?

A: Yes, retrofitting with a CNC control system (e.g., Siemens 828D) is feasible. The upgrade includes installing servo motors, ball screws, and a controller, typically completed within 2-3 weeks.

Q: What maintenance services are included?

A: We provide a 12-month warranty covering parts and labor, plus lifetime technical support for hydraulic system calibration and mechanical wear inspection.

Q: How is the worktable surface protected against wear?

A: The table features a hardened steel plate (HRC 55-60) with a 5mm thick wear-resistant layer, continuously lubricated by a pressure oil system (0.2-0.4MPa) to form an oil film barrier against metal-to-metal contact.
