Overview
Product Overview
The Double Column Vertical Turning Lathe Machine is designed for turning large-diameter, heavy rotational components in a stable vertical orientation. The workpiece is secured on a horizontal rotating table, allowing gravity to support its mass while the crossbeam and vertical tool posts position the cutting tools. The twin-column structure provides a rigid bridge around the work zone for demanding heavy-engineering operations.
The range includes PDCVTL5231, PDCVTL5240 and PDCVTL5260 models. Maximum listed turning diameters extend from 3150 to 6000 mm, table diameters from 3000 to 4500 mm, and workpiece capacities from 10 to 32 tons. The largest model accepts a listed workpiece height of 2000 mm, while the smaller models list 1600 mm.
Suitable operations can include external and internal cylindrical turning, facing, boring, grooving, taper machining and related processing of large rings, discs, wheels, flanges, housings and industrial components. Horizontal and vertical tool-post travel, crossbeam positioning and controlled table-speed ranges support different workpiece envelopes and cutting conditions.
Typical users include power, mining, pressure-vessel, pump, valve, rail, marine and general heavy-engineering manufacturers. Final model selection should account for the complete workpiece diameter, height and weight, chucking and clamping, tool access, material, interrupted surfaces, required tolerance, surface finish, lifting arrangements and expected production duty.

FAQs
Frequently Asked Questions
What is a Double Column Vertical Turning Lathe Machine used for?
It is used for suitable turning, facing, boring, grooving and taper machining of large, heavy rotational components such as rings, wheels, flanges, housings and pressure or power-industry parts.
Which models are available in this range?
The supplied range includes PDCVTL5231, PDCVTL5240 and PDCVTL5260, with progressively larger turning diameter, worktable, workpiece weight and machine envelope.
What is the maximum listed turning diameter?
The PDCVTL5260 lists the largest turning diameter at 6000 mm. PDCVTL5240 lists 4000 mm and PDCVTL5231 lists 3150 mm.
How much workpiece weight can the machine carry?
The listed maximum workpiece capacities are 10 tons for PDCVTL5231, 12 tons for PDCVTL5240 and 32 tons for PDCVTL5260. Load distribution and clamping must also be evaluated.
Why is a vertical lathe suitable for large components?
The work rests on a horizontal rotating table, allowing gravity to support heavy, large-diameter parts. This can simplify loading and provide stable support compared with suspending the same component horizontally.
What table-speed ranges are provided?
PDCVTL5231 and PDCVTL5240 list 2–50 r/min, while the larger PDCVTL5260 lists 2–25 r/min.
What should be checked before selecting a model?
Check maximum component diameter, height and weight, clamping arrangement, cutting-force requirements, tool reach, material, tolerance, finish, crane access, foundation, electrical supply and output targets.
What information should be provided with an enquiry?
Provide complete workpiece drawings, stock and finished dimensions, weight, material, operations, tolerances, finish, batch quantity, workholding needs and installation-site information.
