Internal Details

Box‑Type Ribbed Structure · Excellent Rigidity & Vibration Absorption

The vertical lathe castings adopt internal grid‑shaped reinforced rib layout. Combined with heavy‑duty base and large‑cross‑section box‑type column design, overall structural rigidity is greatly improved. It effectively restrains cutting vibration, and maintains stable machining accuracy under heavy‑load continuous cutting and high‑stock‑removal conditions.

Optional ATC Tool Magazine · Automatic Tool Change for Composite Machining

Available as an optional upgrade for CK51 and CK52 vertical lathes, the ATC tool magazine delivers abundant tool storage capacity to fit turning, milling, boring and drilling tools. Working together with the machine tool’s rigid structure, it realizes fast automatic tool exchange, cuts down manual tool‑setting time and avoids frequent tool changes by operators. It enables one‑clamp composite machining for complicated disc and shell‑shaped workpieces, greatly improving production efficiency for multi‑procedure heavy‑duty parts processing.

Heavy‑Duty Worktable · High Load‑Bearing & Rotational Stability

The worktable of single‑& double‑column vertical lathes is constructed from high‑strength cast iron with optimized internal rib arrangement. Equipped with heavy‑duty rotary bearing structure, it delivers extraordinary load‑bearing capacity to accommodate large‑diameter and heavy‑weight workpieces. Precision‑finished friction mating surfaces ensure smooth and steady rotary motion, minimizing rotation‑run‑out error even under full‑load condition. Excellent heat dispersion performance restrains thermal deformation during long‑time continuous operation, consistently maintaining high‑precision rotary accuracy for heavy‑duty turning, boring and facing processes.

Pre‑Tensioned Ball Screw · Zero‑Backlash for Heavy‑Duty Turning

Pre‑tensioned ball screws on X/Z axes eliminate backlash completely, delivering rigid, snappy axis response even under aggressive heavy cuts. Less friction means less heat build‑up, minimising thermal drift during long production runs. You get consistent positioning & repeat accuracy batch after batch, cutting scrap rates and extending screw service life for your vertical lathe.

Heavy‑Duty Guideways · Outstanding Damping for Tough Cutting

Heavy‑duty guideways ensure rigid, vibration‑free axis movement even during high‑power heavy cuts. Excellent shock‑absorbing capability dampens cutting chatter, protecting surface finish of large workpieces. Low‑wear guide surface maintains consistent motion performance year after year, preventing precision drop caused by long‑term heavy‑load operation and delivering reliable part quality for your high‑volume production.
