CK5250 CNC Double-Column Vertical Lathe

The CK5250 CNC double-column vertical lathe is designed to handle large-diameter and heavy workpieces that cannot be processed on conventional horizontal lathes. Built on a fully ribbed, thick-walled cast-iron bed, the machine ensures high structural rigidity, allowing operators to perform deep cutting, heavy roughing and precision finishing on components up to approximately 5000 mm in diameter. This makes the CK5250 suitable for industries such as energy equipment, wind power components, shipbuilding, industrial machinery, mining equipment and heavy flanges.

The dual-column architecture provides enhanced vertical stiffness, reducing deformation under heavy tool pressure and maintaining cutting stability during extended machining cycles. Both the crossbeam and column guideways undergo hardened and precision-ground processing, ensuring smooth axial motion and long-term accuracy retention. The wide-span guide arrangement absorbs vibration effectively, which is essential when machining large cast iron parts, alloy steel rings or large cylindrical housings.

The CK5250 typically features a high-torque spindle driven by a powerful motor, enabling low-speed heavy cutting and high-speed finishing within a flexible speed range. This allows the machine to handle diversified processes such as face turning, inner-hole machining, external diameter cutting, bevel turning, cylindrical finishing and even irregular profile machining when paired with CNC contouring operations. The large worktable, supported by a strong bearing system, ensures stable rotation and distributes heavy load evenly, enhancing machining precision and prolonging component life.

With CNC feed control on multiple axes, the CK5250 supports multi-pass automatic machining, contour turning, automatic tool compensation and programmable machining routines. This not only improves efficiency but also reduces operator intervention, providing reliable consistency for batch production. Precision ball screws, servo systems and reinforced saddle design minimize backlash and maintain high repeatability—important for sectors requiring high geometric accuracy.

The machine is also equipped with advanced lubrication systems, a full-protection enclosure and optimized chip evacuation channels. These elements extend machine longevity, reduce maintenance intervals and keep the workspace clean. For workshops processing oversized workpieces, the CK5250 offers an essential combination of stability, accuracy and processing capacity.

The machine is highly compatible with cutting tools used in heavy turning, including carbide inserts, negative-rake roughing tools, high-feed cutters and large-face turning tools. Embedded keywords relevant to global buyers include double-column vertical turning machine, large-diameter CNC vertical lathe, heavy flange machining lathe, industrial ring cutting machine, vertical turning center for large parts and heavy-duty CNC vertical lathe.
